Sat this exam this morning, took me about 35 mins for 47 questions and i made a 935/1000.
I dare say this exam was "easy".
Alot of what i had read on here from folks who took the Beta of this exam said it was difficult, but i didnt find that to totally be the case.
For preparation i used:
Microsoft Virtualization Ebook
Microsoft Elearning Courses: Hyper-V technology
Microsoft Elearning clinic: SCVMM 2008
Lab with Dell 2950 running 2008 Datacenter with Hyper-V and a VM to run SCVMM.
The best part is all of the preparatory materials and exam were totally free thanks to finding free offers for things from MS and the lab being at work.
