VCP510 experience from Matt Liebowitz
I was searching through some blogs and came across recent VCP510 experience, below is the excerpts. Hope it helps you in preparing for exams
So for those that are studying for the exam, if you don’t have any real hands on experience with the product you may find the exam more difficult. I’d recommend getting a lab setup and playing with the features. If you’ve used ESX/ESXi for years or at least have been using vSphere for the last couple of years you stand a better shot of passing just based on your experience. You should still study the new features of vSphere 5 and any changes to the way things work, but having hands on experience is key to passing.
