VCAP6-CMA Design Study Resources

A very quick posting around the creation of my new VCAP6-CMA Design study resources page now that the beta exam has been released. As I have done in the past for the VCP5 and VCAP5-DCV exams, I have started building a list of resources I will be using for the beta and if I don’t make the mark then the GA exam for the VCAP6-CMA design. If you feel I’ve missed any resources please do let me know as these pages seem to be very popular and so everyone can benefit with top class resources.

For those signed up for the beta, good luck!

VCAP6 Design Beta Exams Released

A very quick posting around the release of the VCAP6 design beta exams. I know the internal VMware round was happening this week and now they have opened the design beta exams for the DTM,CMA and DCV https://blogs.vmware.com/education/2016/02/new-vcap6-beta-exams-now-available.html . make sure you register for the one you want most first as the validation can take a bit of time and you can only do one authorisation at a time it seems. Here’s hoping the VCAP6 beta exams go better that the VCP6 beta exams did.

What Changed Between My Two VCDX Design Submissions

I’ve been asked quite a few times what did I do differently in my architecture design between my first submission and my second so I thought why not put out a posting around some of those changes whilst not breaking NDA and also still making people work at it so they learn like I had to which has benefited me greatly.

  1. The first change was that after my defence I did what Lior has  recommended in his VCDX Attempt, Strike One – Part 3 posting and wrote down all the places I thought I was lacking and needed to strengthen for my next attempt. I also ensured that the feedback I got from the panel around my weaknesses (these are fairly generic for eg. “ Recoverability was lacking in the logical design” ) were addressed in my design so that I wouldn’t have those problems next time.
  2. I got good design review feedback from peers and my mentor that were also generic in that they told me to look at an area and think about all the decisions there without telling me what was wrong. This may seem harsh but I think it’s the best way and keeps to the mentors “code of conduct” as it makes you learn how you can do better without someone telling you what to change as then 1. You aren’t learning and 2. It’s your design not theirs.
  3. The next change was one that took quite a while due to me having to retrofit it into my design but I implemented and applied the requirements matrix mapping Rene mentions in his posting to ensure I had clear mapping between my conceptual,logical and physical design sections. A large portion of this was implementing all of the design decision tables into my design for all my design decisions. This method was/is brilliant and really makes you think about every possible option and why not only did you choose one of them but why you didn’t choose the others. This also helps you remember in the defence why you made these decisions and why the others weren’t the most optimal. An example of one of the logical design tables that I had for VDC is below:Design Decision – DRS Enhanced vMotion Compatibilityimage
  4. I  read through my whole design whilst doing the requirements matrix mapping and with now more experience as an architect behind me made improvements to my design and simplified wherever possible so that the solution not only met the customers requirements but was also operationally easier to manage once I walked out the door. This also applied to my operations guide where I made improvements.
  5. I ensured all my physical design decisions mapped to validation/tests within my validation guide thereby proving I had validated them and the test we ran to prove this. As stated before my design was a real world design so these tests were actual ones I had done before and actually had in my original submission but the mapping of these ensured there was a clear link from conceptual all the way to validation.
  6. I standardised and simplified all my diagrams. For my diagrams I had a few that I had used varying colours for when I first built the design to make it look flash but all it made them look like were that they came from different sources. For my design I tried to standardise all the colouring and not make the colours neon colours and also simplified them where applicable so they made more sense.

How did you get into using VMware?

I was at a Chicago Microsoft Users Group and a company called Altiris was speaking about virtualizing applications with their solution. The whole idea was pretty eye opening to me so when my boss suggested some enhancements to our infrastructure the virtualization concept was brought up again. After some testing we decided that VMware was the clear leader in the space so we virtualized our infrastructure on 4.0.


What made you decide to do the VCDX?

The VCDX certification was a challenge I wasn’t convinced that I could achieve, but I had to know for sure. A few other co-workers already had the credentials and I decided it was the time to find out what I was capable of doing.


How long did it take you to complete the whole VCDX journey?

The whole process took me about six months to complete. I already had my VCAP-DCA and VCAP-DCD before I decided to try the VCDX so that helped, but I left myself plenty of time to work out my design before submitting it.


What advice would you give to people thinking of pursuing the VCDX accreditation?

Talk with your family first about the endeavour. The VCDX is challenging, but more than that time consuming. Expect to spend nights and weekends working on it. The VCDX journey is personal achievement but can’t be done without some support from family, friends and co-workers.

Aside from talking with your family first, the second piece of advice I’d give is don’t be afraid to fail. This isn’t an easy challenge and many really qualified people have stumbled on it. It doesn’t mean you’re not awesome, it just means you need to tweak your design or presentation skills a bit.


If you could do the whole VCDX journey again what would you do differently?

I would have made sure to understand the defense blueprint better from the start. I felt that there were specific sections of the blueprint where I didn’t have enough things in my design to present. Specifically my design didn’t have a lot of “Security” related items so I wasn’t able to talk in depth about it in my defense. If I could have done it over I would have added an additional security requirement and supported it with my design so that I could talk about it in the defense.


Life after the VCDX?  How did your company respond?  Was it worth it?

After the process was over I was recognized at our company’s Tech Summit and given a bonus for the achievement. The feeling of a sense of accomplishment from meeting a personal goal made the process worth it.

How did you get into using VMware?

After finally scoring a server role back in 2005 I was introduced to ESX 2.5 and GSX, right then while like some kind of black magic I saw the potential and tried to be actively involved when it came to installing, configuring and supporting the platform. Later in 2009 I was leading a team 100% dedicated to VMware technologies that supported local and global accounts right up until 12 months ago when I made the jump to work for VMware.


What made you decide to do the VCDX?

The VCDX for me was my own personal challenge which I set some time ago.


How long did it take you to complete the whole VCDX journey?

This question is a difficult one to answer technically I attempted to start the journey in 2011 but unfortunately was diagnosed with Non-Hodgkin’s Lymphoma which put the brakes on for some time.

But after everything I finally found the time to complete it and restarted the journey late 2014. I was ready for PEX defence where I was accepted but was unable to get time off work. So defended in June instead, this gave me a little more time to polish off some rough bits in the design.

All up about 6 months of solid work it took to get across the line.


What advice would you give to people thinking of pursuing the VCDX accreditation?

My advice is:

· Keep the design simple, it doesn’t have to be complicated

· When it comes to the presentation take advice from people but do it your way, do what flows well to you. Just because X worked for me doesn’t mean it will for you.

· Don’t over prepare if you feel yourself losing interest or just want it to end have a couple days off kick back relax and get back into it.


If you could do the whole VCDX journey again what would you do differently?

I don’t think I would have done anything differently as far as the preparation I did, I think if anything I would have dialled back the amount I did, towards the end it was becoming a chore where its meant to be fun and something I want to do. Also I don’t advise writing a book at the same time that didn’t help at all.

Life after the VCDX?  How did your company respond?  Was it worth it?

The response from family, friends, the VMware community and work was fantastic. And for me personally was worth it. Having something to show for all the time and effort was fantastic.

As for life after, nothing has changed but I have noticed at the engagements I’m on my word has more sway than it did before, or I’m just imagining it. Either way I think VCDX will definitely open up doors which would have been shut previously but for now I’m just catching up on sleep.

Blog Sponsor – Pluralsight

I am pleased to announce the second sponsor of my blog: Pluralsight . I am really excited by this sponsorship as I have been a massive fan and user of Pluralsight’s and previously Trainsignal’s videos and online courses for years and they  have helped me pass all of my certifications within the last 7 years so you can understand how fond of the courses I am.

Pluralsight

Pluralsight’s purchase of Trainsignal has enabled the videos to now be available via your tablet and gives you the ability to download videos to your tablet so you can watch them without needing Wi-Fi like on a train or plane. I honestly can’t recommend them enough and would highly recommend you give them a try and sign up for their no obligation 10-day free trial. They have videos ranging from VMware technologies, learning programming languages from scratch or advanced courses , Windows technologies,hacking, A+ N+ , leadership courses and Scrum fundamentals to name but a fraction of the courses. For some of the certifications I have recommended and personally used Pluralsight courses for and will be using again in the future have a look at the following study resources pages and blog posting:

How did you get into using VMware?

I came into IT when virtualization was just getting started. The more time I spent on call in the middle of the night the more I became motivated to find solutions. Application clustering was too costly for the developers and no business unit would agreed to it. Then came VMware it provided a live solution to hardware failures and great manageability benefits. At first chance I encouraged a proof of concept using VMware. Within the next two years we were 90% virtualized.

What made you decide to do the VCDX?

At some point every technical person is faced with the choice to specialize in their field. When I looked at my possible options I was faced with some tough options. I have to choose between operating systems (Linux), Storage or virtualization. It was the same year I had the opportunity to attend my first VMworld (2012). While attending the conference I really enjoyed being surrounded by such a great eco system and company. I was able to have some great technical discussions with people and I love the conference. It became clear to me that I wanted to specialize in VMware. I needed to learn a lot more about VMware. I have always found that certifications make me learn with purpose so I started setting certification goals for myself. Since I had been in a technical role the VCAP-DCA made sense. Once I passed that test I just kept going.

How long did it take you to complete the whole VCDX journey?

I got a VCP5 on Feb 2012. The certification journey really started with VMworld 2013 when I passed the VCAP-DCA and IaaS exams. This was followed up by the VCAP-DCD in Oct. 2013. I started on the VCDX on January of 2014 and submitted the design May 2014. The VCDX is not really a destination it’s really about becoming something not achieving it. I feel that my life’s experiences from a young child are part of my VCDX journey. I spent two years as a missionary for my church knocking on doors in Michigan. I like to think that really prepared me to stand my ground in a design defence better than any mock defence ever could. At the same time I feel like I am still trying to become a VCDX, I have a lot to learn.

What advice would you give to people thinking of pursuing the VCDX accreditation?

I have lots of advice and there is a write up on my blog (poorly written). The three largest pieces of advice I can give are the following:

  • Don’t kill yourself, set goals and keep them but keep balance don’t sacrifice the world for a cert. Lots of people think they are going to get it done by pulling all nighters… don’t it’s not going to end well.
  • Your design does not have to be perfect.. it’s not about perfect, nothing is perfect.
  • The key to school is figuring out what the teacher wants… read the blue print figure out what the teacher wants and do it… don’t try to outsmart the teacher.
  • Find a format for your documentation and stick with it.

If you could do the whole VCDX journey again what would you do differently?

Spend less time trying to figure out the format and more time on content.

Life after the VCDX?  How did your company respond?  Was it worth it?

LOL… well I switched jobs the week before my VCDX defence so the new employer was happy. I am still getting used to life after and a new job. Was the VCDX worth it? Yes, in fact even if I had not got the VCDX it was worth it. I learned so much about design… preparing for the VCDX forced me to learn more in six months than the last two years. If your desire to become a VCDX is purely in order to get a new job or more money you may not be on the right path.

What is next for you?

Great question. More certifications just don’t tell my wife… I already have the VCP-Cloud and I just finished a massive vCloud project and I am moving into a VCAC and NSX project so VCDX-Cloud might be in the future. Short term I think it’s time for a CCNA to help smooth over a rough bit in my knowledge.
