I am very excited to have completed my 4th refresh of the VCP-DCV Certification on Oct 20th. I even passed with my highest score ever. 412.
I read it cover to cover and found myself recharged when reading processes that I was familiar with.
Sometimes though, the best way to remember something is to see it done..
So I FIRED UP THE LAB.... and it died... hmmm.. probably should have swapped out that USB boot media when I had the chance. Probably will need to figure out how to recover vSAN with a lost host...
So I FIRED UP THE OTHER LAB ! And I performed an upgrade of the vCenter to 7.0.3!
I tried to upgrade the hosts, but the boot media on these were internal SD cards... error "not enough space for upgrade"
So I powered off and removed one of the blades to get a closer look at the SD cards. 2GB Mirror in the Dell M520 blades. 2GB?! ah , ok , wow.
So I slotted it back in with the intention of addressing that again later, and thats when one of the RAID controllers failed.
I only know that because I tried to refresh vCenter after repowering the blade and realized it was not loading. A quick look at the hosts showed why. The snapshot chain had become corrupt. Trying to commit the snapshots failed. Trying to consolidate the virtual machine, failed.
At least the domain controller survived..... nope. Black screen , restarted, crashed on boot. Direct to Windows recovery options. I could get into directory services restore mode, but no repairs would stick. Dang.
So vSAN lab is down, Dell Lab is down.. This would be a great opportunity to learn some things... but I am short on time.
So, on a prior recommendation from a friend and colleague , I checked out a 7 day trial of CBT nuggets. Fortunately they had an updated course for the VCP-DCV 2021 2V0-21.20 exam presented by Keith Barker. I wanted to see some specific topics so I jumped around a bit, but I did find Keiths style very engaging. More than a few times things didn't go 'as planned', sometimes this was on purpose , other times it was the lab he was using, but it was interesting that some of these things were left in.. because, honestly things do not always go right and it would be wrong to present only 100% success every time.
Ultimately I was able to salvage a domain controller from the vSAN lab, (host 2 is dead in the water though) ...
I built a new vCenter and Domain controller on the Dell kit.
Read some more, watched Keith for a few hours, ran a couple of scenarios on my labs, ran a couple of scenarios on hol.vmware.com.
Then, I got a good nights rest.
I went to the testing center, sat for the exam, second guessed myself a few times. Reviewed the questions that I had "marked" and determined that it was probably more harm than good to go back to them (it was only 9.. and of those 4 were marked because I thought I might need them)
I clicked the button to submit. AND BANG! Screen says congratulations.
Very relieved. I don't have to take it again, I can sit for the VCAP-DCV Deploy now... so it starts all over again..
Wish me luck on November 2nd!
Jason
