291 DNS Suggestion

I'm sure some one has suggested this book at some point on this forum, but I figured it has been a while. If you are preparing for 291/293 I highly recommend this book be included in you studies:

DNS is heavily tested on 291 and was responsible for my only failure of an MS exam. This book really helped me out the second time.

Let it never be said that I didn't do the very least I could do.
You might do well setting up a couple of servers and testing ZXFRs, creating secondary, forwards and stubs.
I highly recommend anything from James Conrad (CBT Nuggets).
I thought the entire book was great and it does a good job of covering areas that are particular to Microsoft. It also deals a bit with BIND integration. Sadly it was too long ago for me to recall any details about what I found most helpful.
Stupidboy makes a good point about DNS being straightforward, it would seem to be. But then you get to that dang test and it clobbers you. The way I fix this is by over learning. I learn way more than I need to and it helps.
