Negative Positive
Title: Not very in depth. But certainly Good for the Exam
Review: If you really want to know the stuff, get the cisco book. Both books are very dry. They are hard to follow mainly because the technology presented in these books/tests are 70% outdated. People are using VPNs now and yet this test does not cover that. Don't forget to download the errata for this book from osborne.com. Bottom Line: By using only this book, you will certainly pass the test. For more indepth knowledge, get the cisco book.
