So far this has been an excellent book to learn about the CISCO certification process.

After reading user reviews here on Amazon, I realized that this book, the 4th edition, was lacking in some areas...most notably, NAT. This deluxe edition though, included the virtual lab which I thought would be important since I do not have actual equipment to practice on.

I'm glad that I went this route. I passed the exam today using this book, the virtual labs, practice tests and bonus exams included on the two CDs. I took approximately 2.5 to 3 weeks to study. I enjoyed the way the book is written and layed out. At no time did I find myself falling asleep in material that was not presented well enough to keep me awake. I supplemented my education in the areas that others had complained about and past my 55 question test with room to spare.

If you do not need nor want the virtual lab, go with the later 5th edition of this book.

I used this book for review and am able to pass all the test questions in the cd included. I sat for my CCNA today and it the questions I got where not covered all that well in this book. The test coved Frame relay and OSPF heavly and this book did not cover it as well as need for the exam. In my oppinion you should use a more current released book that covers the new test format and as always use several study books and resources.

Todd Lammle seems to be The Name in CCNA preparation. I bought this book after reading recommendations from other CCNAs at the forums on www.techexams.net.

This book contains the complete guide to the curriculum as well as some very useful background material on the CCNA certification itself and the format of the exam.

The material is presented in a logical manner and consistent with the requirements for Cisco's exam. The style is readable and entertaining.

The material on the CDs is also very useful, particularly the virtual labs, for when you don't have access to real routers and switches.

Although I haven't yet completed my study I feel this book will prepare me well for the CCNA exam.

One thing potential buyers of this book should be aware of: the PDFs on this book are protected by the FileOpen DRM software. This precludes reading the PDFs on anything other than a Windows box, amongst other legitimate uses. In my humble opinion the presence of DRM software is a consumer rights issue and should be clearly indicated by the publisher, which in this case they do NOT.

Even my grand mother from the remote bush of Africa could have read this book and pass her ccna exams. Only if she had had the chance to grab hold of this book before she passed on.

Jesus!! I never new IP subnetting was that easy.
Oh!! the CLI(command line interface) did i say command or cash line interface? Well I now know it.

In fact as a newbies all the way from the Jungle with no IT background. This book was just too good for me, all the others almost scared me of from CCNA.

This book reads easy, explained clearly what u needs to no, concepts are well detailed out in an understandable manner.

In fact this book for me is a six stars not only for preparing for the CCNA Exams but also for just given people like us who knows nothing about the theory and concept of networking the opportunity to read and understand what it is all about. How it works, and how to use and apply it in pratical situation.

I definitely will recommend it to any one who is just starting with CCNA or networking for that matter so also to those who wishes to refresh there memory.
