Summary: Too many errors in this book - don't bother
Review: I am one of the Technical Reviewers of the book. I myself prepared for the CCNA 2.0 exam using the pre-published copy of this Quick Review book and aced the exam in January this year! I also used the Sybex Study Guide.The major strength of this book is its organization. The quick review of exam objectives and quick review tables section in each chapter give a clear idea of what should be reviewed just before one proceeds to the testing center. More than 400 questions are exactly the type one gets in the real exam. The CD ROM has all the questions and detailed answers in the book in PDF format and are good for easy reading. The book serves as an excellent review book for the exam. I highly recommend it to all CCNA aspirants!!

Summary: Book is fine; practice exams and answer keys disappointing
Review: The book presents the material in a concise, effective manner. After a couple hours of buying the book, I was able to read the first two chapters with ease and do the first two exams. However, in grading the exams, I found the answer key to be wrong and answers contradicting text in the first two chapters. Also, so many questions use negative logic that the questions become unnecessarily confusing. I recommend using the Cisco Press books.

Summary: Too many errors in this book - don't bother
Review: There are many errors in this book, especially in the review questions (which form the bulk of the text). To begin with there are problems with the answer keys not matching up to the questions (eg. section 2.4). The answers will say that the correct answer is "B. True", but if you read the question, "True" was option A, not B. Sometimes the answer is not even answering the question that was asked (eg. section 8.3 a question asks about 'default routing protocol' and the answer given is for 'default networking protocol'). There are many typos which make the questions incorrect (e.g. use of the word 'port' where the word 'protocol' clearly should have been used). And the author's explanation of the number of packets exchanged during a TCP three-way handshake and a graceful termination almost defies belief! (Clue: in TCP there is no such thing as an 'SEQ' packet for starters). The intention of the book as a 'quick review' was a good idea. But the sheer number of factual errors make it a very poor choice. Don't waste your money on this one.

Summary: Read The Sybex Book Or Cisco Press
Review: This book was a real watse of paper. It might be useful as a review for some but it is very thin on info. I would pass on this and get the Sybex or Cisco Press book.
