Hello Duncan Epping,
Thank you for your interest in the VMware Certified Design Expert program. I am pleased to inform you that you have PASSED the Enterprise Administration Exam.
For everyone that still needs to take this exam be sure to do the VI3.5: Deploy Secure & Analyze course and read the blueprint before you even start. It be worth checking out Jason’s blog on VCDX and on VirtualTroll you can find links to study material for the Design Exam. (Most of the Design Exam study material are also valid for the Enterprise Exam!)
So for everyone that still has to take the exam, prepare well! Know your esxcfg-* commands, and be sure to know the basics inside out!
