My Certified Wireless Network Administrator (CWNA) Certification Experience

As of Friday, October 14th of 2011 I am officially a Certified Wireless Network Administrator (CWNA). The vendor neutral certification is designed and put forth by CWNP, Inc which stands for Certified Wireless Networking Professional.

My Experience:

I’ve had hands-on expereince with Wi-Fi products since the early parts of my IT career. It was nothing spectacular. I was a pinch hitter between help desk, the Sr. SysAdmin and the network administrator at a 300 person organization. The network admin would frequently have me track down ad-hoc networks, sniff for signals as he played with the 3Com-based enterprise wireless network, perform authentication tests and generally be his gopher. I’ve mucked about with my own small wireless deployments for clients as well.

The meat of my networking experience has been with 802.3 as it comfortably wriggles its way through UTP cabling. Most of my formal training with wireless has been through Microsoft-centric networking topics. However, I felt pretty confident with wireless networks in general even if I knew I wasn’t aware of the deep inner workings of it all. I figured it would be a simple matter to focus my mind on the topic and “get to the bottom of things.” How complex can it be? It’s like the ethernets, just with no tubes.

Exam Motivation:

Now that I’m a consultant (distancing myself from the term “contractor” and the culture that surrounds it), I feel a greater need than ever before to have certifications to show off to prospective clients. Also, even though I’m 29 I still have people look at me and assume I’m barely out of high school. I’m sure I’ll appreciate my Dorian Gray genetics later on in life, but for now my boyish looks can be a barrier to convincing people to trust me with five and six figure projects in spite of my experience and references. Certifications are another leg that I can stabilize a corner of the bargaining table with.

As I gazed at the certification landscape, many seem viable. CCNA? GSEC? JNCIA? RHCSA? CCDA? LPIC-1? I have a decent breadth of SysAdmin / NetAdmin knowledge, even if it’s only a few inches deep in some areas. However, at least I know what I don’t know (at least, I think I know what I don’t know… you know?) and in many cases I merely have to polish what already exists to progress from dilettante to journeyman and eventually on to craftsman / artisan. The wireless networking arena had captivated my attention a few months ago as I saw the needs of small and medium businesses and how they could be solved with wireless networks. With that hunch I decided to pursue the CWNA as my first foray into the realm of invisible tubes.

Exam Preparation:

I took full advantage of a great promotion that CWNP is offering right now: Their Self Study Kits are being sold for the exact same price as the exam voucher. The study kits come with the official Sybex book, a voucher to get official practice exam questions from CWNP, Inc (it’s always nice when the exam creators also make the practice questions), a dictionary of Wi-Fi terms and the voucher that you give to Pearson VUE to schedule your test. The exams are $125, $175 or $225 depending on which level of expertise it is, so for the same price as the test you can get a great book and some practice questions. I believe that this promotion will end with the new year, but can’t find confirmation of that.

The Sybex Book

“CWNA Certified Wireless Network Administrator Official Study Guide: Exam PW0-104” was written by two Davids, David A. Westcott and David D. Coleman. This book goes above and beyond the bare requirements of the CWNA exam. Many exam preparation materials focus purely on the need-to-know information that gets you a passing score. This is not one of those books. You are pushed beyond the exam outline and into some fairly gritty territory with painstaking detail. Many, many times the authors note that a certain passage or entire subsection of a chapter is beyond the scope of the CWNA, but that the foundational information will help all of the required information to gel. When reading the book you feel less like you’re reading exam preparation material and more like you’re reading introductory wireless engineering courseware.

Raise your hand if you’ve ever read a technical book, especially an exam preparation book, that has made you pause and consider if eating carpet and washing it down with a stuffed porcupine would be easier. Is it a certification prep book? NOPE. Chuck Testa! (Okay, I need to chill out on browsing Reddit for a few… hours). While certain publishing houses are known for producing thousand-page longueurs *COUGHMSPRESSCOUGH*, Sybex has, in my experience, largely avoided that pitfall. This book is a shining example and might be one of the few exam prep books that you keep around for a reference.

The downside of the book is that the practice questions that come with it (20 at the end of each chapter and three sets of 60-question practice exams) were a bit sketchy. The questions were frequently subjective, sometimes maddeningly difficult to interpret and on occasion I felt that a few answers were just plain wrong. I wilted, feeling completely inadequate to take the exam in spite of having thoroughly enjoyed the prose in the book and thinking that I had understood the information solidly. That is, until I took the official CWNP practice tests, but I’m getting ahead of myself.

The CWNP Practice Questions

After the frustrating experience with Sybex’s practice questions and exams, I kicked the dirt, plodded over to my CWNP account and tried my cortex on their practice questions. Joyously, I had a better experience. While I didn’t perform quite as well as I had hoped, the questions were at least fairly worded (with a few notable exceptions, as is common with anyone’s tests apparently) and I only disputed one or two. They were well written and the explanations to the correct answers were acceptably thorough.

My main gripe with them is that the wrong answers are not explained. Often it’s not enough to simply explain why the correct answers are right. Many times there is still some misunderstandings surrounding a wrong choice that need to be cleared up. Going slightly off-topic, this is why I’m so impressed with most of Transcender’s products. They almost always take the time to painstakingly explain why each right answer is right, and more importantly why each wrong answer is wrong. Often I’m more instructed by an explanation behind why a certain choice was wrong than why the correct choices were correct.

The Exam:

Of course, I’m bound by a NDA to stay silent about the specifics of the exam (PW0-104). I will only say that it is a fair exam. I felt like one or two questions were unnecessarily vague, however all of the rest, to the best of my ability to understand them, were very straightforward and tested a person on the standards and their various implementations. There were no “gotcha” questions like there were in the first iteration of the test ten years ago.

If you want to pass, you have to be intimately familiar with the standards and their interaction with each other. You have to know the fine grained details of each protocol and how it operates in different situations. If you do, you’ll pass it without even having time constraints. There’s none of the usual funny business that vendor-centric exams (viz. Microsoft and Cisco) are known to have. I attribute this to CWNP being a vendor neutral organization and the fact that they actually stick to their claims. They have so far stayed very true to their vendor neutrality, however that’s not to the exclusion of mentioning specific brand names in their study materials. After all, someone who is certified in a technology needs to have some familiarity with the vendor landscape to be considered proficient.

The Results:

I passed! I needed a 70% score and earned a 78%. I am required to pass with an 80% score or higher if I want to be eligible to become a CWNP trainer. I’ll need to request a retake if and when a training opportunity comes up, but that’s off in the distant future.

While I’m happy with the results, I’m unhappy with my subject matter knowledge. I was fully convinced that I had failed the exam by the last question. Passing is of little consolation to me if I don’t know the subject as well as I should. Perhaps I got lucky on a few answers. My plan is to take a break this week as I travel up to Colorado for a client (in fact, I’m there right now; this post was written and scheduled on the night of Friday the 14th, the same day that I passed the exam). I may take a second week to stay away from the subject. I might even dive into a different subject for about a month to get some healthy brain-distance between Wi-Fi and myself. However, before the year is out I’m going to return to this study guide and the questions and grind it to pulp as I squeeze out as much information as I can.

My further plans are to gain some of the CWNP’s Professional level certifications (the third of four tiers; my CWNA being the second tier and the CWNE being the fourth and final tier). I’m intrigued by the Certified Wireless Design Professional (CWDP) as I learn more about the deeper design principles of wireless networks. Also, the Certified Wireless Analysis Professional (CWAP) is valuable as I research the finer points of site surveys and electromagnet wave propagation at clients’ sites. At that point, I might as well jump into the final P-level certification: the Certified Wireless Security Professional (CWSP). Everyone is concerned with Wi-Fi security, or at least should be, and regardless of peoples’ concerns, I need to be intimately familiar with securing my designs. If I’m going to be learning all of the above topics, I might as well get a pretty new logo to print on my business cards!

If you work with wireless networks and want to know more, regardless of your stance on certifications or your desire for a new one, at least consider reading the Sybex CWNA exam preparation book. It’s top notch. If you want to go further, I’d encourage you to earn the CWNA certification. It’s a legit credential that appears to be well accepted and respected among hiring managers and other decision makers.

And if you’re in the market for a wireless network consultant (among other things that I’m proficient at), HOLLAH! =)

Worldwide Pricing Change to Microsoft Certifications Scheduled for July 2011

Posted in: Certification, SysAdmin
  |  by: Wesley David

Recently Microsoft Learning sent out an email to its certified professionals notifying us of an upcoming price change in certification exams. You can check out the FAQ for this news item. As of July 1, 2011 non-educational prices for Microsoft exams will go up in the following increments:

  • USD $125 to $150
  • GBP £88 to £99
  • EUR €140 to €150
  • AUD $180 to $206

For more information, see the FAQ page, however be warned that the price calculator requires Microsoft Silverlight. If you don’t have it installed, the page that your sent to to install it is actually an older version than is necessary for the calculator (3.0 instead of 4.0). Seriously Microsoft. It’s a drop down list and a yes/no button. You couldn’t just use JavaScript?

The price hike is supposedly to reflect the value that Microsoft certifications bring with them. Personally, I’m relieve that they’re till as inexpensive as they are. Not many certification exams are under USD $200 these days. If anyone wants to save $25 then they’d better schedule and take the exam before July 1. I wonder if I can cram for my 70-643 in time…

Review of Train Signal’s “Exchange Server 2010 Training” Set

Posted in: Certification, SysAdmin
  |  by: Wesley David
Tags: Train Signal, Training

In this blog post I am going to review Train Signal’s “Exchange Server 2010 Training” DVDs, but before I do I would like to make a disclaimer:

Begin Full Disclosure:

I received the title “Exchange Server 2010 Training” for free from Train Signal as part of their effort to get real-world reviews of their products from technologists in the field. There has been no incentive given to me to review the product or provide a favorable review. The only thing that I received out of this is an expensive set of training for free. Train Signal and I have not even had direct contact concerning this Exchange Server 2010 Training review other than that they shipped the product directly to me. I was contacted through my blog by a third party that Train Signal has contracted to garner community reviews and asked if I would be willing to review the product. All of the communication was professional and completely dispassionate. At no time have I felt that I was being influenced in one direction or another concerning my opinion.

The only affiliation I have with Train signal is that I have in times past included an affiliate link on the side of my blog through the Share-A-Sale affiliate marketing website. That is entirely voluntary and I chose to use that link because of my previous favorable experience with their training. I included that advertisement because I believe that their products have been of good quality in the past and want other people in my profession to benefit from the good training. I have removed that affiliate link temporarily while this blog entry is the main story in an effort to be as detached as possible and provide a completely unbiased review.

End Full Disclosure.

I have sectioned this post off into five main areas. You can jump to them here. There’s a TL;DR summary for those of you who have a server migration to get to and just want the Cliff notes.

  • Disclaimer
  • My Expectations. Here I explain what my preconceived notions are about the training and what I hope from it. Most of their thoughts were gathered before I experienced the training.
  • My Judging Categories. Based on the expectations I have, these are the categories that I will be judging by.
  • The Review. Time to put the shoulder-length rubber gloves on because this could to get messy.
  • TL;DR. Synopsis.
  • The Judgment. I judge the training on a scale of five based on several categories that I made for video training.

My Expectations

  • Lots of PowerShell information! Gritty, grimy real-world PowerShell knowledge. Exchange is increasingly causing administrators to need to know PowerShell and no training these days is complete without significant instruction in it. I’d like to see some “gotchas” or some information given that you would only find out the hard way after having worked with the product. Exchange 2007’s EMC had a number of those.
  • I want Real-World material. I don’t want a verbal rehash of the Exchange 2010 TechNet articles. If I wanted that I’d record myself reciting articles about DAGs. If it sounds like the trainer is just reading from TechNet, then it’s not worth it. I’d like to hear some in-the-trenches style information being given. That’s where real value is found.
  • In reference to the above, I want to see some problems in the environment that the trainer has to work through. I get suspicious when I see everything work perfectly in a training environment. It doesn’t happen like that in the real world and seeing someone that knows a product as they troubleshoot an issue can be very instructive. The videos need to be professional, but “professional” doesn’t mean that you have to cover up all errors. “Professional” means disclosing the errors and showing how you worked through them.
  • I want a comparison of what Exchange 2010 is now, compared to previous versions. Most people will be coming to 2010 from previous versions and will not be just freshers starting from scratch. There are still a lot of 2003 installations out there due to 2007’s hardware requirements and a bumpy economy.
  • I want to see information about the possibility of operating Exchange 2010 in a hosted environment. The 2010 version of Exchange marks the departure from using HMC to operate Exchange in a multi-tenancy environment. Now, the ability to run Exchange in a hosted environment is “baked in” using the /hosted switch. I realize that not a lot of people will be using it, so Train Signal might be saving their effort and catering to a broader audience, but I think it’s a disservice to Exchange and techs if there isn’t some time given to it. I’d like to see a whole video about it, but might have to settle for just a few minutes. If there’s no mention at all I will be sorely disappointed.
  • I want good quality audio and video! No popping P’s or sizzling S’s. I do not want to listen for hours on end to someone that is using a headset microphone. For $397 USD, this kind of training should be done in an insulated booth with a stellar microphone. The video should be big and crisp. No fuzzy downstepped flash files.
  • I want the trainer to have decent speaking skills. If you’re going to do video training or in any way be verbally training people, you should have a decent ability to orate. I don’t mean to say that the person needs to be the next William Jennings Bryan, but at least have some ability to communicate effectively.
  • I am hoping that this training will not be purely a certification course. Yes, the training is marketed as aiding you in passing the 70-662 exam for Exchange Server 2010. However, that’s not the main thrust of the marketing. The product is marketed as an Exchange Server 2010 training course that also preps you for an exam. If this is just about passing the certification exam then it’s not as useful as it could be.

My Judging Categories:

  • Thoroughness of the topic. Does it include information for large as well as small installations? Does it include information concerning operating Exchange in a hosted environment? Does it offer ideas and support for people who might be using all the various parts of Excahnge?
  • Real World: Is it just a rehash of Microsoft Technet? Does the trainer work through problems that happen as the training is going? It will count against the training if there are no problems at all with the scenarios. Is this just a Microsoft brochure that does not mention any third-party possibilities to supplement various features?
  • Relevancy to the Microsoft exam: Yes, the training is also geared to helping you pass the 70-662. Does it map to the official Microsoft “Skills Measured” sheet for the 70-662 exam?
  • Physical Packaging and Presentation: Does it look good or like someone used Walmart DVD+Rs and printed labels on their deskjet?
  • Virtual Packaging and presentation: Is it just a bunch of files dropped onto a DVD or is it presented well with a launcher? What extra goodies are there, if any, besides just the videos themselves?
  • Audio Quality: For the price people are paying, the audio ought to be studio quality.
  • Video Quality: If I’m going to be watching 20 hours’ worth of videos, I don’t want to be squinting or looking at fuzzy on-screen text. The training environment needs to be big and bold!

The Review:

As I sit in my home office typing this, I have written most of the text that you see above without having looked at the training that I am about to review. I wanted to create my expectations and judging criterion without seeing the training beforehand. I have used Train Signal training in the past and have had a mostly favorable experience. I say mostly because I have taken exception to the quality of the audio in at least one training series as well as the size of the screen recordings in all of their videos. The recorded area on the trainer’s computer has, in my experience, always been distractingly small (800 x 600).

There are three Exchange 2010 training packages that are currently available from Train Signal (as of November 2010). The first is simply known as “Exchange Server 2010 Training”. That is the title that I will be reviewing in this blog post. The second title is known as “Exchange Server 2010 Design and Deployment Training”. The third and final title is known as “Exchange Server 2010 MCITP Training Package” and it includes both titles.

“Exchange Server 2010 Training”, has a total of 40 videos spread out over 10 sections and costs $397 USD. You can see the entire synopsis at Train Signal’s page for the Exchange 2010 Training series. Like all of Train Signal’s videos, when purchasing the video series you can have instant access to them via the Train Signal website and they also ship the DVDs to you free of charge. That’s right, shipping is free… worldwide.  Boo-yah!

According to the Train Signal website, each customer will receive a free code for a Transcender practice exam of their choice. I did not receive the Transcender practice exam code in my evaluation copy of the training, however I have a lot of experience with Transcender exams and know that they are of high quality.

The packaging that the training comes in is a standard DVD case. There are three DVDs in the case. Two of them contain the videos themselves and a third disc has additional content, iPod, mp3 and wmv files. The packaging is well done, orderly and of standard quality for a set of DVDs that you’d buy in a store. I liked the fact that contact information for Train Signal was printed prominently on each disc and a business card was slipped into the case with a “Thank You” printed on it as well as more contact information.

To use the contents of the DVD you can use the Flash based Train Signal menu to browse and select videos or simply browse the DVD’s file system to choose the lessons you want to watch. If you use the Flash menu to select a lesson, the video will be opened up in your default web browser within a simple but elegant web page located on the DVD.

The Flash Menu:

The Local Web Page:

I find the flash player menu to be too small which cuts off the full lesson names. You can expand the window, but the flash contents simply resize to fill the window in the same proportion as before which defeats the one of the purposes of expanding the window.

Furthermore, playing videos in your web browser uses the Windows Media Player Plugin which has slightly different features from the full-featured Media Player. When I watch or listen to training I speed it up because no one ever talks fast enough for me to learn well. Depending on the speaker I move it from 1.6 to 2.0 times normal speed. However with the media player plugin it only has three speeds, Fast (1.4 speed), Normal and Slow (0.5 speed). Thus, I prefer to browse the DVD’s folder hierarchy and open the AVI files directly.

To play the videos you need the TechSmith Screen Capture Codec (TSCC). You will most likely not have those on your computer. Links to download the codecs are included in the Flash menu program and the web page that each video is opened up in. The codec installers are included on the video discs or you can download the latest version from the web. The codecs support Mac OS 9, Mac OS X and Windows.

The trainer in this video series is J. Peter Bruzzese. He’s definitely got a passion for Exchange. He’s a Microsoft certified trainer who has taught Exchange for a number of years. He’s had a hand in writing several Exchange books including the Exchange 2007 SP1: How-To by Sams. He also writes www.ExclusivelyExchange.com. Seems like the kinda guy you want to teach an Exchange course.

When it came to to launch my first video I was greeted by an 800×600, 15 fps recording. Unfortunately Train Signal (TS) has still not increased the size of the trainer’s recording area so many of the windows that the trainer works with are cramped. The trainer is constantly resizing windows and panes and in one case had to make the Windows taskbar auto hide to be able to click the buttons on a window. I know that increasing the size of the recording area would make the recordings larger and probably necessitate more DVDs per package, but in my view: “Oh well!” It’s unnecessarily distracting throughout the whole series of videos. DVDs are cheap in bulk, DVD cases with the same form factor but holding 4 (or even 5) DVDs are mere pennies more in wholesale quantities and from my research, bulk DVD duplication and printing services would only add just a bit more than a dollar per boxed set. Make the vids bigger, TS!

Just a Wee Bit Cramped:

The trainer, J. Peter Bruzzese, was obviously in a studio setting. No headset mics here! Or if there were, it was the greatest headset mic EVAR. It was great audio that was easy to listen to. Good job!

J. Peter makes the claim that the video series is not about “which buttons to push to make things happen” but rather making an Exchange 2010 organization “from scratch” (I’m quoting the introductory video in the series). He specifically stated that he wants to give his audience the “why factor” so that you can think on your own and understand the information because you have a “why” or a reason for what you’re doing. (After watching the videos, the claim held true for the most part.)

The scenario presented in the series is to take a fictional company, Globomantics, and move them from a hosted Exchange solution to an in-house installation of Exchange 2010. Also, Globomantics acquired a Brazilian company that has an Exchange 2007 organization that will need to be brought into the mix.

The deployment scenario is large enough to where multiple roles must be installed multiple times across multiple sites. Each time Exchange is installed he shows a slightly different way of doing it which is nice and thorough. All the separated roles make for a very engaging environment that requires you to stop and think as new requirements introduced into the scenario and implemented.

I was excited to hear that the training included a hosted Exchange scenario! However, as the videos progressed I grew more and more disappointed when I began to realize that there was not going to be any specific mention of how to migrate off of hosted Exchange to in-house Exchange. That scenario was only mentioned to make it feasible for a portion of the training to be about building a medium sized Exchange organization from scratch for an already established company. There was no mention of migrating data from a cloud to on-premise Exchange servers. I do realize that the video series is primarily about Exchange in-house, but still found that the mention of hosted Exchange in the scenario ended up being a tad bit misleading.

This video series is not for total administrative noobs. You must have some kind of preexisting understanding of TCP/IP, Active Directory (including AD site topology and groups), and DNS. Basic understanding of Windows Server 2008 will greatly help you as well. You are expected to have at least some familiarity with concepts like certificates and the basic administrative tools.

While you should know something about basic network and server administration, you don’t have to know anything about Exchange. The course is designed to teach people in a manner that best suits a person with no Exchange experience.

In the introductory video, J. Peter speaks concerning the 70-662 exam. He specifically states that while the video course will cover the topics in the exam objective list, the teaching is not in the exact order of the exam objectives. That is because the order in the objectives sheet is not the logical order to learn Exchange from the ground up. I was encouraged by J. Peter pointing that out since it deprecated the importance of merely learning for the sake of passing the exam in favor of genuinely mastering the subject.

In an early video, J Peter shows how he set up the lab that he will be working with. That way anyone can duplicate the lab themselves for hands on experimentation. However, if you don’t have the hardware to create the relatively extensive lab (at least seven virtual servers), there is an example of a simple lab that you can create. Think of it as a “shoe-string budget” lab. There is even a lab setup PDF that you can read.

There’s also a PDF of the slides that are used in the teaching videos as well as a place for notes on those slides. I’m not sure what exactly they’re good for, but hey… it’s nice to have if you’re into that sort of thing.

Speaking of slides, each video relies heavily on bulleted slides as well as slides that have network maps of the latest iteration of the Exchange network as it is being built out. The bulleted slides are meticulously talked through and are very good at reinforcing what is being learned. The network maps are a bit cheesy looking, with some of the representations of servers still with the white rectangular outline around them and others with a proper transparency. Okay, so no big deal, but c’mon. This stuff ain’t cheap and piddly mistakes like that add up and sully the product’s overall appeal.

Really?!

Also, some of the more complex network maps are not laid out well enough to show which servers are virtual and which servers are physical. An example is video 33’s network diagram. It would have been nice to see which servers were in what DAG groups (in the high availability videos) and what databases are replicated with which servers. Sure, the specific section on DAGs shows the server/DAG breakdown, but a larger pull-back of the network map didn’t. As a result it wasn’t clear which servers were holding what groups and databases across multiple sites.

Speaking of the network maps and servers, the servers were named in a way that was a fair characterization of how they would be in a real business environment (“EX2K10CHMB1, EX2K1PRIME, EX2K10MB2”), but it was a hindrance to keeping track of what was being done on which server as the network and scenario got more and more complex in the later videos. The complexity itself was great! The server names could have been more helpful. J. Peter himself made reference to it in a later video by saying that they might be confusing to the viewers, but he was used to it because he had worked with them and built the network.

Indeed, there are many servers in this lab, however the lab’s setup and the trainer’s care both combine to do an admirable job of making sure the viewer knows which server they’re on at all times (even if it takes a few seconds to visually parse the confusing server names). The lab uses BGInfo on all servers so that the server name and domain are imprinted on the desktop for all to see. J. Peter frequently points out which server he’s working on as he switches back and forth between machines. Very well done.

PowerShell’s dominance in the video series is established early on. For example, in video 5 J. Peter shows how to add Windows features using PowerShell and mentions that it’s actually easier to use PowerShell than the Server Manager GUI. Also, he shows that TechNet has cmdlet snippets that you can copy and paste to get more familiar with the scripting language. I liked those encouragements to use PowerShell. He mentions several times that in many instances it’s easier to work from PowerShell (which was nice to hear someone say). Too many people think that the command line is the harder way of doing things. This quote from the video was also excellent: “It’s important to start getting comfortable with PowerShell. Whether we like the idea of doing things from the command line or not, it’s really part of the future of Windows Server, part of the future of Exchange and this has been the case for a few years now. So if you haven’t really embraced PowerShell just yet, well, let’s work through that slowly. […] You’ll see that it’s really not that bad.” SWEET!!

As for the “real-worldness” of the videos, there were a few instances of in-video errors that had to be handled. Most of them were PowerShell mistypes. Video 7 had an error in a PowerShell script that he worked through. There was a mistake in typing out a command in the video about edge server subscriptions that was worked through. Some other little mis-typed commands existed as well, but there were no major issues that had to be troubleshot. You could see that as a good thing or a bad thing. I see it ever so slightly as a bad thing. I definitely felt like it was a sterilized lab environment. I was especially suspicious of a few areas in a video where a quick cut was made in which you could see a few windows had slightly changed. I wondered what had to be done behind the scenes and if there was some quick hacking that was performed to get something to work. To be fair, that’s merely my suspicious mind at work. Perhaps J. Peter had to make a quick phone call in the middle of a video and paused the recording.

In many instances, J. Peter pointed out certain options, features or cmdlets that were not working very well in the SP0 version of Exchange 2010 that he was working on. Some of the features seemed rather obscure so that showed me that he was definitely an in-the-trenches Exchange admin. One example involved manipulating an SSL certificate in PowerShell. He explained that he tried it once, then a second time and then finally with the “–verbose” switch which inexplicably caused the cmdlet to work. Another example was pointing out that when running Exchange’s setup.exe, you should run it from an elevated command prompt and not PowerShell because launching via PowerShell doesn’t work too well when setup.exe has to make Active Directory schema changes. Wow. Glad I found out about that issue now and not later.

Adding to the real-world feel of the videos was J. Peter’s willingness to frequently talk about third party solutions to various problems. Examples include showing the limitations of Exchange’s built in archiving, journaling and general MRM features and when you might need a third-party solution to supplement the built-in features. Limitations with the built-in Windows Server backup were addresses as well as network load balancing. He suggested when you might want to look into third-party anti-spam solutions in the form of software or even hardware appliances. This is not Microsoft-centric training and J. Peter is not afraid to show when the built-in tools might not be enough based on certain scenarios.

The trainer does not just rely on “lore” and experiential knowledge when teaching. He shows where you can go on TechNet to find information straight from Microsoft. He also encourages the use of community forums. In my opinion, he was not using TechNet as a crutch to help teach for him, but was using it in a “teach a man to fish” sense to foster self-sufficiency in the viewer. In several places the viewer is encouraged to dig into PowerShell for themselves, look at the get-help output and find out the nuances of various cmdlets.

Public folders, in spite of their deprecated status, were given some fairly in-depth treatment. The PowerShell cmdlets necessary to administer the public folder infrastructure were given prominence. I was surprised at how little information was given about public folder replication. There seemed to be an assumption that the viewer either knew about it already or would find out more from other sources as necessary. I recall Train Signal’s Exchange 2007 video training going into more detail and was, in fact, where I picked up a majority of my understanding of public folders.

Outlook Anywhere, one of the greatest Exchange features ever, was explained but lacked troubleshooting guidance. I felt there could have been a lot more scenario-based training using the Test-OutlookConnectivity cmdlet as well as the use of the Exchange Remote Connectivity Analyzer. He criticized ERCA slightly when it came to Outlook Anywhere troubleshooting, but didn’t go into any detail (or use the tool to demonstrate troubleshooting).

There was no mention at all of Exchange in a hosted environment. I’ll let this one slide, for the most part, since so few people will be installing Exchange with the intention of making a multi-tenant environment. I’m still a tad bit disappointed.

I noticed an unfortunate trend, however, that started as I made my way through the videos on the second DVD. As the topics become more complex, the demonstrations became less in-depth and there was a lot more theory discussed in the slides. There became more and more topics where no work was done in the lab at all. For example, the Unified Messaging portion of the training was contained in two videos and they seemed to be merely a discussion of theory and some hurried run-throughs of each checkbox and input on the dialog boxes involved in setting up UM. I realize that UM is a massive topic, however there were no examples given of dialing into an Exchange mailbox or calendar or leaving voicemails for people. No proof that the UM server was functioning properly was given. Sure, it would have taken a larger lab in the Train Signal offices… but isn’t that just the cost of doing business? The UM section felt very surface-level.

By far the biggest disappointment involved the topics of backup, restoration and high availability. Backing up with the built-in windows backup tools was shown briefly. However, there were no examples of restoring messages from the dumpster. No examples of restoring messages from a backed up database after the dumpster time period had expired. There were no examples of restoring databases. No examples of restoring servers. It was all theory. That is, in my opinion, inexcusable. I would have felt very unhappy about spending $397 on training that did not show examples of multiple restoration scenarios. It was all dealt with in conversation while looking at slides. Anyone who knows about the various possible restoration scenarios knows that they are not trivial and merely conversing about them left me confused and frustrated.  There was a much more thorough and hands-on treatment of data restoration in the Exchange 2007 video series from Train Signal.

High availability for two of the Exchange 2010 roles was only addressed in theory as well. Edge, hub transport and mailbox server HA was addressed by example in several videos. However the UM and CAS roles were only dealt with in theory on slides. Leaving out the UM role could be excused since it’s as simple as installing another UM role and sharing the same dial plan among them (as well as tweaking your PBX to know about both UM servers). However the section on CAS server redundancy was a disappointment. CAS server redundancy was lightly and confusingly addressed. Admittedly, it requires third party load balancers on the front end (oddly, Microsoft’s own NLB is not supported) but that could have been handled by some “hand waving”. It would have been just fine to say “Okay, pretend we have a f5 load balancer on the network…” before configuring multiple CAS servers. Virtually No mention of MAPI A records in DNS were made except for a split second mention of “Once you’ve got your DNS setting configured properly, then you need to…”. No mention of load balancing MAPI RPC ports was made. The PowerShell cmdlets necessary to make a CAS array were touched on however it was only on the slides; no real-world examples pertaining to the lab itself were given.

I checked to see if a more in-depth coverage of those topics would be included in the second series of Exchange 2010 videos that Train Signal offers. According to Train Signal’s website, the “Exchange 2010 Design and Deployment Training” series does indeed delve into the topic of high availability for CAS servers however I was surprised to see very minimal mention of backups and the word “restore” was not on the webpage. I have not evaluated that video series so cannot say for sure if it does or does not go more in-depth into the topics that were ignored in this video series, however if the website’s description is any indicator, it appears that there is minimal coverage in the second series as well. Possibly even less than is in this series.

No doubt adding in-depth training about restoration and Unified Message and CAS role high availability would have extended the training onto a third DVD, but again, is this about keeping production costs down or training someone thoroughly on a topic? I admit that I am making a complete assumption that the training was left out due to production costs which might not be the case at all. Nonetheless, this was a gaping hole in the training and very disappointing. Backup restoration is not a topic that should ever be treated sparingly. Major points deducted.

The last videos in the training address checklists to go over before taking Exchange 2010 live, prepping for the 70-662 exam and where you can move on from there to learn more about the expansive topic of Exchange 2010 administration.

I should mention that I did load both the videos and MP3s onto my iphone. The MP3s are of limited use just because this training is, by nature, visual. I tried to listen to a lesson while taking my morning walk and it just didn’t work out. The topic was one that I was familiar with so I thought I could get away with it, but frequently I found myself unable to follow the lesson because it relied on visual input. That’s not a problem at all, since this is, after all, video training and not audio training. It’s a nice gesture that the MP3s are included, though.

After watching the approximately 40 hours worth of training (condensed into probably 20-something hours since I watch them at 2x speed) I was impressed with J. Peter’s speaking skills. He delivers the information in a very good manner, with even speaking and a good pace. He is obviously an experienced trainer and not just a technologists who landed a deal to make some training videos.

TL;DR

The first DVD is a great introduction to the banality of Exchange administration. The second DVD takes a sharp downturn in topical quality, however. There was a superficial treatment of the Unified Messaging role that did not include any examples of the role functioning properly. I did not see any troubleshooting for Outlook Anywhere except a few brief mentions of a tool that you could use to help out (no examples given). However the inexcusable sin was that lack of backup restoration examples. None! No mail message restores, no database restores… nothing! It was all theory that was discussed while looking at slides.

The information that was present was given in a very practical manner. J. Peter is not a Microsoft fanboy and is not afraid to show where Microsoft’s built-in features either in Windows Server or Exchange itself might not cut it for an organization. He frequently suggests third-party solutions that he has experience with. He briefly demonstrates PowerGUI as a means of manipulating PowerShell. He talks about what configurations of Microsoft are supported and which ones aren’t, but has no problem saying that in spite of a configuration not being supported (the UM role being virtualized, for instance) that doesn’t mean that it won’t work just fine if you do it. He also points out buggy “gotchas” that only experience can teach.

Train Signal thoughtfully provides iPod versions of the video, MP3s, videos explaining how to use the iPod files, PDFs of the slides and lab design. However you have to dig through the CD’s folder structure to find some of them. The Flash based menu that first launches is just shy of useless. There’s not, to my knowledge, a good single point of reference for everything that’s available to you on the discs. I had to go exploring to find what was available to me. Should video training feel like an Easter egg hunt?

The quality of the video itself, from a visual standpoint, is great. It’s not blurry. However there’s very little use of pan and zoom and no “callouts” to point out what the trainer is speaking about if there is a mention of a specific visual item. Once in a very great while a zoom is used to show that a small icon has changed, but those seemed to be ill framed, a bit rushed and I still wasn’t immediately sure what I was supposed to be looking at as a result of the zoom. I’ve done video editing for commercial training before and know that it’s time consuming, but it’s necessary and is a help to students. The 800 x 600 resolution on the trainer’s computer has got to go. It’s distractingly small and even the trainer struggles with it in his environment.

Overall, the training is well produced and decently presented. I’d prefer there to be a more comprehensive menu that shows what all is on the disc. It would be better if the menu wasn’t based on flash. The virtual death blow to the video series is the absence of thorough training for the topic of backing up and restoring data. Other topical absences nickled and dimed the training even further. Is it worth the $397? If I had paid that amount for it I would have felt disappointed. In my experience, this is not Train Signal’s norm. Their topics are usually much more thoroughly addressed. I recall their Exchange 2007 training addressing the topic of data restoration much better.

If you have an abundance of money, are an extremely visual learner or have the ability to draw on a corporate training budget… go for it! You’ll definitely learn useful information and have a great base of understanding to move onward and upward in your Exchange 2010 knowledge. If you’re on a tight budget or have a decent amount of experience with previous versions of Exchange, I’d recommend passing this title by and selecting a few good books or hanging out at some Exchange communities online.

The Judgement:

  • Thoroughness of the topic. 3/5 (lack of backup restoration shaves a full point off. Superficial treatment of the UM role as a whole with no usage examples takes a half point off. The other half point is for the remaining faults such as the superficial treatment of the CAS and UM high availability topic, no Outlook Anywhere troubleshooting and no mention the ability to install Exchange in a multi-tenant environment. The second DVD felt to me like I was just being read to out of a training manual… because that’s pretty much what was going on.)
  • Real World: 4.5/5
  • Relevancy to the Microsoft exam: I’ll fill this back in if I take the 70-662
  • Physical Packaging and Presentation: 4/5 (It’s not trendy kewl like an Apple product and doesn’t feel like a warm hug from a suspiciously outgoing office manager [you know the one I’m talking about…], but it’s sharp looking and does the job. I’d be proud to have it on my shelf of books and training miscellany.)
  • Virtual Packaging and presentation: Is it just a bunch of files dropped onto a DVD or is it presented well with a launcher? Are there more items than just the training videos? 3/5
  • Audio Quality: 4.5 (Perhaps the midrange was slightly too harsh. 1K and 4K frequencies might have been a tad high)
  • Video Quality: 3.5/5 (So cramped! No post-production learning aids.)
  • Overall: 3.5/5

Free Microsoft “Career Campaign” Vouchers

Posted in: Certification, SysAdmin
  |  by: Wesley David
Tags: Microsoft

UPDATE: This offer has expired as of 2011.

Microsoft has launched a program to help individuals further their existing IT career or start a new career in IT. It’s called the “Career Campaign” program. With this program, you can select a voucher code that can be used for as few as one exam or as many as five exams. Each time you use the voucher code to book an exam you will receive a percentage off of the booking price and will also receive a free second shot on each of the exams you book should you fail the first attempt.

A “Career Campaign” voucher that is good for only one exam is subject to slightly different rules. Instead of a percentage off for booking the exam, you actually pay 15% more on the initial payment, however that 15% extra allows you to have a second shot should you fail the exam. If you pass it on the first try, yes, that means you paid an extra 15% for a single exam – but at least you had peace of mind knowing you can retake for much cheaper. If that’s any consolation.

Let me give you three examples:

1) Jessica is a SysAdmin who wants to get an MCITP in Enterprise Messaging for Exchange 2007. That particular MCITP requires three exams: 70-632, 70-633 and 70-634. She selects a 3-exam Career Campaign pack voucher. She uses that voucher when signing up at Prometric.com for each of her three exams. She receives a 15% discount when she pays for each exam and also gets a free second shot with each exam should she fail it.

2) Wesley is a SysAdmin who needs just one more exam to finish his MCITP:Enterprise Administrator (that would be me, by the way). He uses a single exam voucher to book his exam. He pays 15% more (a total of $143.75 USD) but has the added protection of a free second shot should he fail his first attempt (which wouldn’t be the first time that has happened).

3) Finally, Tara is an IT noob who wants to go certification crazy. She uses a 5-exam pack to book each of her 5 exams. She pays 20% less for each booking and also receives a free second shot for each exam. Tara is happy. Microsoft is happy. The trees are happy because certifications from Microsoft are sent via PDF and no longer printer on paper. Rejoice!

Some other bits of useful information convcerning this promotion:

  • FULL DISCLOSURE ALERT: For every voucher code that is successfully used, I receive 10 points in my Learning Rewards account. I can convert those points into “Rewards”. Currently there is only one reward available: a three month XBox Live Gold card, which is utterly useless to me since I don’t own an Xbox.
  • If you fail an exam, you must request a retake voucher using this Prometric form. You must wait 72 hours after failing an exam to request a retake voucher.
  • Only commercial exams (070) are eligible for this offer.
  • You have to obtain the voucher and sit for the exam by June 30, 2011
  • If you have questions you can contact Microsoft at [email protected]
  • You can only register one exam at a time and you cannot register for a second exam until you have taken the previous one.

Without further rambling, here are some USA Career Campaign vouchers free for the taking. If you use a code, post which one you used in the comments so I can remove it from the list. If you need more, want codes for a different country or want to make a “bulk order”, let me know. I can create as many as necessary in any country on the planet.

20 Free Vouchers for Discounted MeasureUp Practice Exams! (Select Microsoft Exams Only)

Posted in: Certification, SysAdmin
  |  by: Wesley David
Tags: Exam, Microsoft
 

The Microsoft Learning Rewards program allows me to create unlimited exam voucher numbers for all Microsoft IT Professional and developer certification exams and all Microsoft Dynamics exams (all 070 exams). The program runs various campaigns and in the past has allowed for the creation of “Second Shot” vouchers. Unfortunately, the current campaign is not so helpful and offers no discount to the test taker, but does allow the voucher creator to earn points for each voucher used. [insert head scratch here]

I believe the program is aimed more at trainers who encourage their students to take the exams that the trainer’s class covers. The trainer will then give out vouchers and receive a small kickback in the form of Learning Rewards Points which can be exchanged for items like a month of Safari Books Online or a TechNet Subscription.

So if the vouchers do not give test takers any discount, why am I giving them away? Because the vouchers can also be used to get up to 40% discounts on select 60-day online Microsoft practice exams from MeasureUp! Simply use this link to search through the exams that are offered and then insert one of the voucher codes below to receive your discount!

It is worth reiterating that the only kinds of exams that you can get a discount for are 1) Select Microsoft Exams (not the entire catalog of exams), and 2) 60-day online versions; not the full download version of the exam.

You can also use these codes when scheduling any Microsoft IT Professional and developer certification exams and all Microsoft Dynamics exams (all 070 exams) in the United States and I’ll get a few points in my Learning Rewards Program, but you… well, no soup for you.

 

If you choose to use one of these codes, please say so in the comments and I’ll cross off the codes that have already been taken. I can create unlimited numbers, so take as many as you want. Let me know if you want to place a large “order”.

40 Free USA/UK Microsoft Second Shot Vouchers Good Until June 30, 2010

Posted in: Certification
  |  by: Wesley David
Tags: Certification, Microsoft

Because I’ve taken at least three Microsoft exams in the last five years (probably around a dozen or more), I was recently invited to participate in the Microsoft Learning Rewards program. The program encourages the distribution of discount exam vouchers amongst the IT Professional community. I just signed up for it and generated 20 Microsoft Second Shot exam vouchers that are good in the United States and 20 that are eligible in the United Kingdom. Both sets of vouchers expire by June 30th, 2010. That means you must schedule and take both your first and second exam by June 30th, 2010.

Do you live elsewhere and would still like some Second Shot vouchers? I can generate vouchers for virtually any country on earth. Drop a comment and tell me what country you’d like codes for. Australia, anyone?

Note that these are not vouchers for free exams. You must pay the full price for a Microsoft exam, however, if you input this code in the “Voucher:” field in the Prometric sign-up process (just before you click the link to pay for the exam), you will be allowed to retake the exam one more time for free if you fail (as long as the retake is taken before June 30th, 2010).

But wait, there’s more! (I didn’t really say that, did I?) You can also use the Second Shot voucher code to get 40% off of any MeasureUp 60 Day Online Practice Test for a Microsoft product. The MeasureUp offer also expires June 30th, 2010.

Full Disclosure: I receive a “kickback” of sorts from this program. For every voucher that is redeemed, I receive 10 “points” that can then be converted into an item from the Microsoft Learning Rewards product catalog. At the moment, there are only two things available. The most valuable to me being a free exam voucher when I reach 60 points. It’s kind of a win-win situation for everyone.

Send this list to your friends, and if you want me to generate codes for more countries, just let me know! When you use one, post a comment including the code that you’ve used and I’ll cross that code off the list. Same goes for if you find a code that doesn’t work (probably because someone used it and didn’t notify me).

United States Second Shot Voucher Codes:

  • 9205DWV43G
  • 9205DWW1RC
  • 9205DWX5PF
