I took this exam at the end of June and passed on my first try. This was also my first Microsoft exam.
I found the test prep in the Microsoft Press study guide to have questions which were closest to what I saw on the test. I have ExamForce as well, and none of their questions were even remotely similar to what I saw on the test.
None of it was difficult. I didn't have any questions where I was baffled. I had a good number of network related questions and they weren't hard . If you have some familarity with subnetting and can understand the diagrams, you'll be fine.
Good luck!!
