I sat the 70-649 this morning and passed!

Overall Score 820, which is the lowest of your three.
70-640 Section 820 (AD Cfg)
70-642 Section 1000 (Network Inf Cfg)
70-643 Section 940 (Application Inf Cfg)
A few questions that through me were on IIS, RODC, and ADRM. Other than that, not too bad.
Used MSPressBooks and really just read through some TechNet articles on 2k8 ADFS/RODC, etc. If I could go back I would read a little more on IIS, but luckily I do not have to...for this exam atleast.
Next on my radar will probably be Windows 7 followed by 647 for my MCITP: EA.
I am not sure if the SA (646) is worth doing first or even at all...opinions?
