Hello,
I've started my studies for 83-640 exam and 83-640 it's supposed to be my first microsoft certification.

I bought 70-640 training kit and I am using windows 2008 servers installed in a virtual machine in order to perform all the exercises proposed in the kit.
I have read that part of 83-640 exam will be based in lab. Is training kit enough to be prepared for the lab part of the exam ?
what about hyper-V ? How can I get prepared to answer questions about it in the exam ?
cheers
