It's been a while since I've last posted anything on here. The last few months have been very busy. I have 10 articles and technical guides in draft that I need to complete and post on the site, but I just don't have the time to complete them at the moment. I'll try and find some time soon to get through the backlog of posts.


So, yesterday I had to go and sit the VMware VCDX Enterprise Admin Exam (VCE310). Although, a few weeks after I had booked my seat for the VCE310 exam, the good people at VMware had come up with the new certification tracks that includes the new VCDX4 certification. I then for a moment was contemplating cancelling my booking for the VCE310 exam, but after thinking it through for a bit and also taking into account the fact that I had to wait for quite some time to get a VCE310 booking from VMware, I decided to go ahead and site the VCE310 anyway.


As I mentioned earlier in the post, things have been very busy the last few months and I hardly had any time to prepare for the exam. For that reason, I arrived at the testing centre yesterday, prepared to take a kicking from the exam. I knew that in the case of me failing the exam, I would at least know what to expect from future attempts.


I'm sure you have seen may posts form gurus that have taken the exam before, so I'm not going to go into too much detail on the exam. To state the obvious, as I'm also under NDA, I will not be able to discuss any questions that were asked either.


The VCE310 exam is split into two parts, each accounting for 50% of your final score. The first part of the exam is the same format as the VCP exam based on questions with multiple choice answers. As I started to work my way through these questions, I realised that it's not actually as hard as I'd first anticipated. However, towards the middle of the first section, I noticed that the exam was starting to get more and more tricky as it was focusing the questions based on a particular technology that I don't know all that much about. I'm not sure if the exam system adapts to your weaknesses or strengths, but I did notice that the system kept on asking me questions around this same technology. Almost as if it knew that I sucked at it! However, towards the end of the first section, I felt as if I was getting back on top of the fight and that the questions asked were fair and reasonable, whatever that might mean.


The second half of the exam is a live LAB. Unlike most exams with LAB environments that basically only emulate a small part of the software that the question is based around, this was actually a live lab running on live servers with real IP addresses user accounts, RDP sessions, remote console sessions, Putty SSH sessions and DNS entries. Every keystroke and mouse movement is tracked and recorded for whomever that will score your efforts to interrogate.

Now, at first I thought "I work with this stuff in large enterprise data centres every day of my life, so this should be easy as." I was wrong. First of all, because you know that your every move is recorded, it adds extra pressure. Also, the remote console session to the live LAB environment wasn't the best. It was “glitchy” and had poor response times. One example is that I had difficulty seeing the navigation tabs in the VI client. But that's the easy part. What I did find very hard was the fact that if you don't know how to do something that can only be done from the CLI using Putty, you basically couldn't perform the tasks asked in the lab question. It's as simple as that. If you don't know how to enable or disable root access for SSH (and this is just an easy example, the real lab questions are much more complicated and harder that this), you simply don't know and you won't be able to answer that question.


In regards to my efforts in the LAB environment, there were two questions that I genuinely didn't have a clue on. Whether that will be enough left out for me to fail? We'll I'll know within 12 days from now. All I know is that when I got home last night, I jumped straight onto my lab to try and find the answers to the two question that I couldn't do in the lab, and to say the least I was kicking myself within 10 minutes of logging onto my lab! As Homer Simpson would say... Doh!


All in all I think the exam is composed to be very failr and reasonable. If I do fail the exam, it won't be because the exam was too hard, but it would be because I did not study. It's as simple as that.


Anyway, up an onwards. If I pass, it would be a bonus. If I fail, then oh well, you win some and you lose some. At least I know now what is expected in the exam, something that even the exam blueprint can't give 100% clarity on.
