Query: What exam are we preparing for?

I have been generally impressed with previous Certification Insider Press offerings. I figured that this book would be up to par and a reasonable guide for preparing for the TCP/IP exam. The author seems to have missed the point. This is an "EXAM PREP" book. What exam am I being prepped for with this book? Only occasionally did I feel that I was actually getting TCP/IP information. The unrelated information may have some value, but not at this stage of the certification game. Chapters on installing NT? Why? By the time an individual is studying for TCP/IP, I imagine that this topic is old hat. One would have been exposed to NT install information for at least the NT Server and Enterprise exams, and possibly even NT Workstation. The case study sections seemed useless to me as well. On the topic of TCP/IP I can say EXAM CRAM--YES, EXAM PREP--NO!!!
