I passed, thought it was blog post worthy so here is the blog post. This is certainly a hard test; the level of knowledge is, well, advanced! The knowledge required goes well beyond VMware settings, check boxes and theory – you are expected to have an advanced (sorry had to do it again) level of knowledge on things such as Disaster Recovery, storage and networking – at least that’s what many of my questions were on.
Preparing for the exam, for me, was a bit of a struggle. There are a lot of great resources from the VMware community for those preparing for the VCAP-DCD with a focus on design such as the #vBrownBags from professionalvmware.com, a list of amazing resources from Gregg Robertson (@GreggRobertson) at his blog (thesaffageek.co.uk), a handy guide from Shane Williford (@coolsport00) which is also available at professionalvmware.com that adds useful resources and notes to the exam blue print and of course a few great courses available at www.trainsignal.com. In my opinion, however, this is not a test you can expect to just study for and pass. The ability to pass the test comes from being hands on with the technology – servers, storage, networking, VMware, etc… and the resources that are available I think are invaluable to those who are coming from an engineering/systems background and want to focus on design. The study guides and examples are certainly excellent in helping you understand the conceptual, logical and physical concepts of the test.
My path was a bit different. For a long time I was positioning my career to move into a CIO/VP level role so I feel like I already had a good understanding of many of the design concepts that the test, and study guides focus on – collecting business requirements, identifying constraints, risks and stake holders and then applying those to design decisions to support the business. Just about a year ago I made a conscious decision to go back to being a geek – hands on, making technology work. Since I was straddling technology and design (well really management but I think they are very similar) already, I hadn’t necessarily had the amount of hands on technical work that I would have preferred to have over the last 5 years.
While there are certainly a number of posts available (such as Gregg’s blog which lists an amazing amount of resources), I will focus on the ones that I used since you could make a career of just studying for the test. In no particular order, with a couple of tips:
- VMware vSphere Design
- Mastering vSphere 5
- VMware vSphere Clustering Deep Dive
- Designing VMware Infrastructure
- #vBrownBag APAC Recordings
- Managing and Optimizing vSphere Deployments
- VMware vSphere Advanced Networking
- VMware vSphere Security Design
- Disaster Recovery and Business Continuity Fundamentals
- Performance Best Practice for vSphere 5.0 (yes the test is still based in 5.0)
- VMware vSphere Upgrade Best Practices
- VMware vSphere HA Best Practices
- VMware vSphere Storage Best Practices
- VMware vSphere VMFS Best Practices
- VMware vSphere VDS Best Practices
- VMware VCAP5-DCD Blue Print and as much of the referenced material as possible
- Shane Williford’s Blue Print Notes
- Gregg Robertson’s VCAP Resources
- Jason Langer’s VCAP Resources and doc package
- 7th Grade Math, well maybe 9th – yes some basic math, most of the materials above will go over the math for their specific discipline but don’t be shocked when some math questions come up
- Keep track of how many design questions you have completed. You are told at the beginning of the test how many you will get. On my first attempt I didn’t and made what probably was a poor decision to skip a question because I was worried about time, in reality I had plenty. This time I knew how many I had completed so going into hour 3 I knew I only had 1 left so I was able to focus on some of the more advanced questions.
- Don’t over think, trust your gut – you can’t go back on this test so if you don’t know it, try to eliminate the answers that are obviously wrong. Or just go with C (I forget what movie that was – Ferris Bueller’s day off maybe?).
Now, don’t freak out (sorry I have seen tangled like 10Million times so this is image burned in my brain), I am not suggesting you need to read each and every line from all of those documents, but you need to be honest with yourself about your strengths and weaknesses. Also keep in mind the #vBrownBag recordings are available via iTunes/RSS (thank you Nick Marshall) and the TrainSignal courses can be downloaded as MP3s so you could always listen during your commute. I received 2 hours of training a day (hour each way) thanks to my commute and the ability to listen on the go.
If you are coming from the engineer/admin side you may have a leg up on the technology side of the test but may need to focus your efforts on understanding design and business need. If you are like me and coming from a design/consulting/management side you probably have to brush up on some of the deeper technology pieces that you may not have to think about often. definitely check out the resources I mentioned above, start to think about the business needs for the technology you are using – why is it needed, what business problem is it solving, focus on documentation and the conceptual, logical to physical considerations and you will be well on your way. Craig I hope this was an awesome-enough blog post.
