Well, before I can get to the VCDX Enterprise Administration Exam it becomes more urgent to get the new VCP for vSphere (aka VCP4).
Simon Long has a practice test on his Slog.
Keep check the practice test site, he has added to it a couple times. I really like practice tests. Helps me know if I know what I am doing. Many times scheduling the exam for me comes down to confidence, I hate to waste $175- $225.
Now to remember how much Memory is required for the vCenter Server…
