Just got back from my exam and passed with a 760. Not as comfortable as I would have liked but just glad that's the final real tough exam out of the way after the 291! Two more needed for the MCSE now.
Got 3 sims (not sure how much I can say here about them) but just to say make sure you know GPMC well as it covered 2 of the 3 sims and one of them almost caught me out to do with some policies that needed to be enforced (intentionally vague)

. The 3rd sim was to do with a CA...very easy one.
There was a total of 43 questions. Majority of the questions were on Clustering/NLB and a fair few on DNS and about 4 or 5 on RRAS.
**EDIT
Should have added what resources I used for studying:
- Syngress 293 study book (very good),
- MS Server 2003 PKI Certificate Security (as recomended here and is VERY good for getting up to scratch on CA's).
- Exam cram (it's ok for a last minute thing, nothing great though),
- Trancender,
- Microsoft white papers on Clustering and NLB (boring as hell but some useful info).
