I agree with Denny, topics covered is 291, such as dns, dhcp, CA, RRAS, subnetting etc are all covered in the following exams in some way or another. wheter it's the 2nd Network Infrastructure exam (293), AD (294), exchange (284 and the exam I'm doing now), or 297, AD design.
The topics covered in 291, especially DNS will help you in every day troubleshooting so is a must to get your head around asap.
It is the hardest exam I've sat so far, there's no getting away from that, but once you understand the topics it covers, everything else just sits on top.
I was at an AD workshop this week at Microsoft and all the instructor kept saying was how important DNS was.

Good luck with 291, and if you're stick post back and we'll try and help
