Advance Praise

“Todd’s methods of discussing topics are tactfully approached so they are not confusing to
the reader, and his explanations are clear and easy to understand.”

—Amazon Reader Review

“I passed my CCNA on the first try after reading this book thoroughly. …If you read the
book and do all the review questions and written labs at the end of each chapter, you will
be well prepared for the exam.”

—Amazon Reader Review

“This is a great book! Todd Lammle has the ability to make complex topics simple. Cisco
books are essential once you’ve mastered networking basics, but there is nothing like Sybex
for learning the concepts from A to Z.”

—Amazon Reader Review

“Todd has been an authority in this field for as long as I can remember. His style of writing
keeps the book from becoming a sleep aid and provides nuts and bolts information that is both
excellent real-world reference and directly relevant to exam objectives. If you are considering
taking the CCNA exam, you would be ill advised to not give this book a thorough read.”

—Amazon Reader Review

“This is the first book review I have ever written on Amazon. I’ve been in the computer/net-
work support field for many years, but had almost no contact with Cisco equipment. I basi-
cally knew the ‘enable’ and ‘config’ Cisco commands. I had originally planned on shelling
out the $3000 to take a CCNA boot camp, but decided that that was way too much money.
So I bought this book instead … took a week off from work (which I would have done any-
way for the class), and went at it ... My homegrown boot camp paid off because I passed the
exam on the first try, saving almost $2900!”

—Amazon Reader Review

“This is the best technical book I have ever read!!”

—Amazon Reader Review

“This book is excellent resource for preparation for CCNA certification. It has needed infor-
mation regarding the Cisco’s objective. Sample test and Bonus Test give extra knowledge for
exam’s question. Users have more knowledge and practice of test exams. I will recommend
this book for anyone who does not have any knowledge of CCNA material.”

“I’ve recently passed the CCNA exam with 985 out of 1000 points and Todd Lammle’s
book was my only study material (along with a Cisco 2500 router).

“It covers all relevant topics in such an easy-to-understand way and gives you a great net-
working/Cisco knowledge to build upon. Even now, while I’m pursuing other certifications,
it serves as an irreplaceable reference. Every chapter concludes with review questions,
hands-on exercises or labs to give you the opportunity of applying your new skills in real-
world scenarios and the CD provides additional sample tests and flashcards to consolidate
your knowledge.

“By reading the book twice and doing all the exercises you will be able to answer just about
any question you may encounter on the exam. Highly recommended!”

—Amazon Reader Review

“I had made three previous attempts using Cisco Press but could not get over the hump.
Needless to say I was getting pretty discouraged. However, I had heard good things about
the Sybex book by Todd Lammle and decided to give it a try. It was the best thing I could
have done. The book read great and it explained the required concepts and topics very well.
The review questions and Hand-on Labs at the end of each chapter were also very helpful.

“I took the test last weekend and passed!!

“Thank you!!”

—Amazon Reader Review

“Good exam prep. I read this book and with only slight network experience was able to pass
the CCNA.”

—Amazon Reader Review

“There isn’t much more I can say about this book than has already been said. I used Todd’s
guide to help me pass the CCNA in 2000 and am using him again to recertify. Just an excel-
lent book. Period.”

—Amazon Reader Review

“This book covered everything I needed to pass the exam, with hands-on experience, and the
bonus material. What a great written book this is. The best I have ever read.

“I recommend this book highly!!”
