I reached a milestone last week! I passed the VCAP-DCV Design 2023 and finally completed my VCIX-DCV path.
For those that are looking for study resources I have included my recommendations below.
For the Deploy exam I drew most of my study from lab time. You can use the VMware Hands-On-Labs or refer to your Production environment. There are a handful of scenarios that you have to solve. If you want to see examples you can check out this YouTube playlist from the VMUG in SriLanka - Question:01 - YouTube
If you are ambitious enough to create your own HomeLab whether it is Physical hardware or using VMware Workstation (included in Advantage) on your desktop - don't forget that VMUG has the Advantage program that give you access to a huge number of products for a full year.
For the Design exam I started with this site:
The first 2 links really are the most important.
I also added any or ALL of the IT Architect Series Books -
I didn't read this one but it was recommended by others - IT Architect Series: Designing Risk in IT Infrastructure, Behr, Daemon, eBook - Amazon.com
One of the things that I was really stuck on was how to properly Calculate and perfectly right size the number of hosts required when given the existing CPU/ Memory or Storage utilization.
This book did a great job of explaining overhead requirements and N+1 or N+2 architecture. - The Complete VMware vSphere Guide: Design a virtualized data center with VMware vSphere 6.7: 9781838985752: Computer Science Books @ Amazon.com
I had access to some of these through an Oreilly.com subscription so you might have more affordable ways to get to some of these.
If you want to follow some YouTube videos, I would highly recommend the vBrownbag EMEA Series that was done for vSphere 6, the information is still HIGHLY relevant and Rebecca Fitzhugh's video on Objective 1.3 (old objectives) had enough examples that I was able to better understand the relationship between the Functional and Non-Functional Requirements and their respective Design Qualities.
The Design exam is going to be retired on Version 7 at the end of this year and the 8 will be available in January or February so the first link is updated with the 8 info.
