Monday I'm going to take the 70-642 exam. Now for this I've studied the official MS book and took the practice exams.
Today I was looking on the net for some test exams and I came across Examcollection.com who has total different questions then the official MS exams.
The exams from examcollection cover new functions like Direct Access and Branch Cache where there is no mention off in the MS book.
So can I trust the examcollection exams to study?
