I have to say that I disagree with all the comments...overall this is a pretty damn good book. The whole idea of these "new" types of exams is not to learn how to setup the network, its how to design it...meaning you gotta know the architecture. The first part of the book goes into the whole business design, which is great for real-world but you won't see much on the test. The last part was much more useful as it explained all the topics covered on the test. I used the AD Design book from Sybex and it worked great to help me pass the exam...so these do come highly recommended.
