Summary: A great resource for passing the 640-801 exam
Review: The Sybex CCNA Study Guide 4th Edition was one of the main study materials that I used to pass the 640-801 exam. This book covers all of the pertinent ideas and topic relative to the 640-801 exam. It provides very realistic practice questions and labs along with sample configurations. The book also comes with a trial version of CCNA CertSim by RouterSim, also from Todd Lammle. The upgrade to the full version of the testing software is only 40.00 if you already have the trial version and I believe that this book, along with CertSim, were essential to my success on the exam. I don't think you can really ask more of a study guide.

Summary: This book just isn't enough!
Review: There are three types of people that would read this book.
The first type is generally someone who wants to read this book and get an understanding of how networks work and a little about the configuration of routers. This book will benefit you greatly because you'll learn all the things that happen behind the scenes when you're using the Internet.
The second type of person is the certification whore, I've gotten a few certifications but only because I was required to do so by my work. This book will provide information on passing the CCNA but can only be paired best with online router sims and something like Boson tests.
The third type that is usually someone that genuinely wants to learn and get the certification. i fall into this category and quite frankly it doesn't do me any good because one year I took the test and failed i realized that testking provides the exact answers for all the tests. All 500 something randomly generated CCNA questions. If you want to really ace the test with this book and hands on knowledge it's impossible. I personally know CCIE people that have taken a look at the new tests and say how much harder the test has gotten since they've taken them.
So find out what type of person you are before getting this book, it can make your decision more positive if you know what you're getting yourself into.

Summary: Very good book.
Review: This is great simulator, works great, feels like the real thing. Does everything I need it to do to take the test. The only problem or really just an irritant was that the hands on lab in the 4th edition Lamle CCNA book don't quite match up to the Platinum Lab simulator. I think they could of done a better job of describing the layout of the lab a little better, (basically none) maybe have a pictured layout of port connection with the available hardware in the lab simulator pages. I noticed quickly that the hands on lab in the book don't match head to head w/ the sim.. I figured it out, yes, It works? Yes. But when the book talks about switch(a) as a 2950 and the lab talks about the same devise as a 1900, its kind of thoughs you off because the commands are so different.. I found that if you save your work between Labs its much, much easier.. I don't know.. maybe it was planned like that to make me dig into it.. I did and I was able to make it work just fine..

Summary: Nothing even comes close to how great this book is!
Review: This is the best Cisco book ever - bar none! If you want to learn about Cisco routers, and pass your CCNA, then this is the book for you!
Don't waste money on any other books or study aids. I have found that I could have just spent the few bucks on this book and receive absolutly everything I needed in one source. What a money saver.
The CD in the front of the book has 1000 practice exam questions, 500 flash cards and the entire book in PDF! Also, there is a program to practice the CCNA sims that you will find on the CCNA 801 exam.
I am giving this book 2 thumbs way up!
Nicely written in an easy to understand and follow manner. What a nice change from the cisco press junk that puts me right to sleep!

Summary: Some Reviewers Leave Alot to be Desired As Well
Review: This is the latest in a edition in a series of books from Lammle and Sybex that has allowed many thousands of IT professionals pass the CCNA Exam. Whatever opinion is expressed and from whatever quarter it cannot be denied that the CCNA is a benchmark exam in the world of IT certification. I am very mystified by the last review as to how the reviewer gained so much knowledge from such an imperfect source to be so imbued with the technical knowledge to be critical to the level he has. As to writing style that is of course a matter of taste. The whole effect gives the impression of one of those alleged "spoiler reviews" which eventually get drowned in a sea of stars in a few months. The CCNA exam has evolved as has the various study volumes and as any exam certification hopefull knows there is not one title that can contain it all. The current CCNA exam needs at least two good sources of information beside the Cisco site, hands on or at the very least simulator experience and detailed study or experience to succeed. Cisco Press is indeed an excellent source as well. It has often amazed me how little outlay is expected in some quarters for such a prize certification considering that this exam can be the cornerstone of many an IT career not to mention futher Cisco qualifications, is a couple of books and a simulator so much??? Even if it is RouterSim! If your serious about study instead of semantics then buy, read and study, study some more and get on!

Summary: All you need to beat the exam
Review: Todd Lammle's book is the definite guide to become CCNA.
I tried another book before but it doesn't bring me the confidence to take the exam. The topics are covered deep and in a friendly manner. Subnetting topic is vital to succeed the test and Lammle did a big effort to explain the topic in a frienly manner. I became CCNA taking the 641-821 (INTRO) and 640-811 (ICND), in both scored more than 900.
So, no matter what exam(s) you take to become CCNA, studying with this book definitevely help you to PASS!

Summary: not that good
Review: Unless you already know the stuff, this book wont help out much. If you already do know the basics, there are better ways to prepare for the CCNA.
