Title: It's got just enough material to help you pass
Review: Remember that this is an "Exam Cram", not a standard study tool. I just passed the 640-505 exam, and I only used this book and some lab practice as my only sources of instructional material. The book doesn't cover all of the test material (e.g., minimal discussion of h/w products), so you really need to rely on another textbook for the basic foundation.I've used some of the other "Exam Cram" series (Routing, Switching) as test preparation tools, and this one is about the same quality (...although the author throws in some humorous remarks that help to keep you awake!) It touches all of the test topics, but doesn't provide in-depth discussion (as intended). However, it was sufficient to help me pass my exam !!
