My VMware VCAP4-DCD BETA Exam Experience

Yesterday, I took the VCAP4-DCD beta exam (VDCD410), like many others have done this week. There is a thread started already in the communities forum. Just like previous beta exams with VMware, I had to take the exam at a Pearson-owned facility. There are a few within an hour of me, so I didn’t need to fly anywhere.  It’s funny, Jason Boche mentions that he couldn’t take coffee into the testing center. The person at the facility where I took the exam said no food, drink, candy, etc. The center where I usually take exams is more laid back and are OK with coffee as long as there is a lid. In fact, they offer to sell you bottled water to take in with you. VMware only requires a finger print scan and a photo with the two forms of ID. I noticed some people were getting their hand vein patterns recorded. Crazy.

Passing the VCAP4-DCD exam is one of the requirements for anyone, including a VCDX3, to achieve the VCDX4 certification. So passing this exam is very important to me.

VCDX 4 Paths

The Exam

The beta exam was 131 questions/tasks with four hours to complete. (There was a guy before me that was taking a test that lasts 630 minutes!) I would think that some of these may get cast off as improper, too easy or too hard. If all of the questions prove to be OK, then VMware has a nice, fair pool of design questions. I would also think that the “GA” exam will only be a portion of these questions.

There are three types of questions or tasks: The standard multiple guess questions, a few “match the object to a category” drag and drop tasks and a few diagramming tasks.

Exam Content – What You Need to Know!

I am under countless NDAs on this, so there will be no “scoops” here. I can say that the exam is true to the Blueprint. Rather than giving a direct link to the PDF, which could change, I will tell you to go to www.vmware.com/go/vcap. Click on the “Datacenter Design” tab. There is a link to the current blueprint there. It was just changed to fix an issue with broken hyperlinks. There are also links to a FAQ, the VCAP Communities landing page and a link to a demo of the diagramming tool.

Make sure you read and understand all of the documents and web pages that are linked in the blueprint. VMware leaves no stone unturned. I would not advise trying to memorize all of the content listed in the blueprint, your head would explode. Just comprehend what you read. Much of this is conceptual and revolves around the methodology and best practices GUIDANCE that VMware chooses to publish.

Make sure you take a look at the VCAP4-DCD Exam UI Demo. This is the exam version of a Visio tool. One of my complaints about the VI3 Design Exam was the quality of the diagramming tool. It is greatly improved in this exam. In the VCAP4-DCD beta exam, there were more than one diagramming task. I don’t think VMware is looking for the Mona Lisa. This is more of a “show your work” kind of thing. The diagramming tasks are not that complex and will only cover a few design criteria in each task.

Since this is a DESIGN exam, there are plenty of scenarios that involve capacity planning. Since you will not have any tools available to do your work, you will need to understand the math involved in capacity planning.  There is a simple calculator available via a link at the top of the screen. You will also need to understand the math involved with calculating HA, DRS, reservations, shares and limits.

Finally, with the beta, there was a time constraint. I think I had about 10 or 15 minutes left when I was done. Make sure you manage your time. There was no “back” button and there was no way to mark questions or tasks for review in the beta exam. This may or may not hold true for the “GA” exam. Remember: If there is no “back” button or way to mark a question, make sure you are OK with your answer before clicking the “next” button. I clicked it a few times as I was thinking “Maybe I should read that again….”

My Soapbox Moment

I don’t want to “toot my own horn” or sound arrogant here, but I purposely did not “study” for this exam. I did read the blueprint and skim some of the documents. The hyperlinks were broken in the 1.2 version and I didn’t try to find them too hard. I didn’t study for the VCAP4-DCA exam either (I passed by the skin of my teeth!). In my (humble) opinion, the exams require that you have EXPERIENCE in the subject of the exam. I don’t think VMware intends to have “paper VCAPs” although I am sure there will eventually be some out there.

If you want to pass the VCAP4-DCA exam, you should have experience managing a vSphere environment. If you want to pass the VCAP4-DCD exam, you should have experience in designing at least one vSphere environment. You need to go through the thought processes involved in the ASSESS – DESIGN – IMPLEMENT – MANAGE cycle. I am sure that the design workshop will assist you in gaining the knowledge and some experience in designing a vSphere environment, but it won’t give you everything you need for passing this exam. Certainly, if you want to progress to the final step and submit and defend a design, you will need EXPERIENCE. This is why there is such a high fail rate for the design defense.

  1. I took it as well. Noticed a few inconsistencies and odd things here and there. Probably left feedback on half of the questions.

    Overall I found the test to not be soul-crushing but certainly challenging if you haven’t done this sort of work before. Some of the questions weren’t completely thought out in the scenario and too much knowledge of a particular topic could bite you in the ass if the guy who wrote the question didn’t know/understand/have the same depth. I wish there was a place where beta participants can go and chat with exam people and discuss the depth further. I’d be curious what feedback others may have left (or may not have left due to fears of time constraints)

    I actually looked at the clock when I walked out the door and I had a solid 20 minutes left. Stark contrast to my DCA experience where I probably had 10-15 seconds left.
