Failed by 12 points the first time and I'm not going to pretend it wasn't demoralizing. I'd been working in vSphere environments for two years and figured the practical experience would carry me. It didn't. The exam cares about very specific configuration details and best practices that you might never encounter in a typical SMB setup.
Second attempt I spent 6 weeks doing focused prep. I went through every VMware official objective, made flashcards for anything involving storage policies, host profiles, and vCenter architecture. The networking section hit me hard both times — NSX concepts show up more than people warn you about.
What really moved the needle was drilling timed practice sets. The exam has 60 questions in 75 minutes and that sounds fine until you hit a multi-part scenario question that eats 4 minutes. Time management matters almost as much as knowledge.
If you're in the middle of studying, don't skip the VMware documentation on vSAN. It's dense but 8-10 questions came directly from that material on my sitting.
Congrats on getting through it! The storage policy section destroyed me on my first attempt too. I kept confusing RAID-1 FTT=1 with the space requirements versus RAID-5. Did you find the Pearson VUE test center experience was consistent with the practice environment?
Appreciate you sharing the breakdown. I'm 3 weeks out from my test date and the vSAN documentation tip is exactly what I needed to hear. Going to block a whole day for that this weekend.
The NSX content is brutal for people whose day job doesn't touch it. I asked my manager to let me spin up a lab environment and that helped more than any reading. Even basic NSX-T segment setup gives you the mental model you need for the questions.
Also — the objectives document is worth printing out. I crossed off each one as I felt confident. It made the prep feel less like a wall of stuff to learn.
Second attempt here too. Mine was a 7-point miss the first time, which honestly hurt more because it felt so close. The vCenter upgrade scenario questions are where I kept losing points. Once I memorized the exact upgrade sequence the second run went fine.
Honestly the biggest shift for me was stopping the "I know this already" attitude and actually reading the official docs cover to cover for vSAN and NSX-T configuration specifics. I'd been doing this stuff in production for years and that almost hurt me because I'd developed my own shortcuts that don't match what VMware considers correct procedure. Second time around I treated it like I knew nothing and just drilled the configuration workflows from scratch.
The other thing that helped was doing practice questions under timed conditions starting about two weeks out. I wasn't just checking if I got it right, I was paying attention to why the wrong answers were wrong, because VMware loves to put in distractors that are almost right. That's where a lot of points leak. If you failed the first time don't assume you just need more study hours, you probably need to study differently.
Congrats on the pass! I failed my first attempt too and the thing that turned it around for me was drilling on the networking and storage specifics — that's where I was bleeding points without realizing it. I found a set of free vca vsphere networking storage management questions that actually matched the style of what showed up on the real exam. Worth going through if you haven't already.
Practical experience helps but it won't save you on the edge cases VMware loves to test. Once I stopped assuming I knew how stuff worked and actually read the official docs on vDS policies and storage policies, things clicked. The exam is very "by the book" in a way that two years of hands-on just doesn't fully prepare you for.
This is exactly the mindset shift that made the difference for me too. I stopped marking practice questions as "got it" the moment I picked the right answer and started asking why the other three were wrong. Sounds obvious but it changes everything. Some of those distractors are wrong for really subtle reasons, and VMware loves to test those edge cases. Once I understood the reasoning behind the wrong answers I wasn't just memorizing anymore, I was actually building a mental model of how vSphere works.
The practical experience thing is real and it's a trap. I'd been doing this stuff for over a year and still bombed certain sections because I'd never had to justify my decisions to an exam. In the real world you just do what works. The exam wants you to know what VMware says you should do and why. Drilling through explanation-heavy practice tests, not just the questions, is what finally got me there on my second pass.
Just wanted to drop in and say this thread gave me a lot of hope. I'm in a similar boat -- sat the exam for the first time last month and missed passing by 8 points. Been grinding practice tests since then and hit 78% on my last full sim, which is the best I've done so far. It's not where I want to be yet but it's trending in the right direction.
I've got my retake booked for September 5th. Fingers crossed. The storage policy stuff is where I kept losing points the first time, so that's been my main focus these past few weeks. Thanks for breaking down what actually matters -- it's genuinely useful to hear from someone who's been through it twice.
Thanks for this post, it's exactly what I needed to see right now. I'm in a similar spot, second attempt scheduled and just starting to actually drill the weak spots instead of rereading slides. Knocked out a practice set on free vca vsphere networking storage management topics last night and hit 74%, which felt decent but I know the real exam's going to push harder on the edge cases.
Planning to sit it in about three weeks. Fingers crossed the structured practice actually sticks this time around, because you're right that real-world experience doesn't translate the way you'd expect.
