I’ve just passed additional MS exam, PRO: Designing Messaging Solutions with Microsoft Exchange Server 2007 (70-237)! Got 935 on it .
This one was easy that previous, 70-236. I’ve got a lot of questions about clustering, HA and multi-sites design. It was just 37 questions in this exam.
The study resources I used to pass are:
Book “Microsoft Exchange Server 2007” http://www.amazon.com/Microsoft-Exchange-Server-2007-Unleashed/dp/0672329204/ref=pd_sim_b_1/191-1807479-9996238 (yes, this book again )
