Hi,
I failed my VCP-DT test at PEX... 285 (300 needed to pass). I didn't prepare for the exam at all, but I have done many View deployement... There was too many question,on feature that I didn't use a lot, so it didn't help me at all. I had 2 hours to kill at PEX, so I took the test as a 125$ mock test. I didnt not have much expectation about my success but I did hope.
Exam is not too hard, but it test thoroughly about the matter, so it is quite fair. I now know what to prepare. Also I learned at PEX that Linus Bourque (famous VMware trainer) will release a VCP-DT book this summer (VMware Press).
So I will perhaps wait for the book before retaking the exam.
