Title: Overall very useful w/ many resources; Still has some errors
Review: This book had some errors, contradicting itself on separate questions involving where to place different types of access lists and giving an incorrect answer for which cable to use for connecting hub to hub (should've been crossover), etc. (on the practice exam). However, it did include a large database of questions (400), flashcards for PC and for Palm, and overall was much easier to read than most texts. While I did take an ICND course provided by my firm, this was my only other supplement (mostly for use in reviewing and taking the practice tests) and I passed on my first time with a 924. I would recommend this book, with the cautionary note that there are a few errors that might minorly test your faith. If you can get yourself to pass the practice exams quickly and understand the concepts behind the questions and answers, you'll do fine on the real test (640-507). Good luck!
