You won't get all the information you need to pass the real test from this book, but that is not its intent. It works well when used for what it is marketed as, which is a "cram" resource to supplement a sound knowledge of SQL Server 2000 administration. Especially useful for me were the practice questions, the practice test at the end, and the screenshots of Enterprise Manager dialogs. Good to have in the hours immediately before the test!
The contents have a few errors, including referring to the model database as "modal" throughout the book, but that doesn't detract too much from the overall utility of the book.
All in all, a good investment, considering the cost of each attempt on the real test.
