I m planning to take ICND1 and this book was recommended as the companion book on one of Cisco s web pages It s no where near comprehensive enough Instead, I recommend the Official Exam Certification Guide by Wendell Odom ISBN 978 1587201820 It covers the syllabus in far depth and includes a CD with a test exam, tools to help with subnetting and video tutorials. The book has good content, however some concepts are not explained very clearly I didn t have too much trouble through most of it, but chapter5 offloads TONS of acronyms on you, which they briefly define, poorly explain, and only use the acronym form of it from then on The end of the chapter review questions are a joke, the answers given in the book are not correct.I decided to download the errata from cisco s website, hoping it would correct it Well you tell me how this is correct Chapter 5 Question 2 Which three communications needs do WANs address A Workers in a small business need to be able to communicate and share data with each otherB Administrative staff within a school need to share schedule information with the teachersC Organizations often want to share information with other organizations across large distancesD A department needs to share large data files quicklyE Students need to do research for classes by accessing library indexes and publications located in other parts of their country and in other parts of the world.F Workers within a branch of a large company need to share project data with each other.Errata Chapter 5, Page 409, Question 2 Answer reads D,F Should read C,E so not only did they get COMPLETELY wrong answers in the book, but the downloaded errata still fails to correctly give 3 answers, and only supplies 2 If you ask me, most of the answers are too vague anyways, and a lot of the questions are like this Hopefully the test won t be so vague.Some of the supplied answers are so blatantly obvious its not clear how this could have happened if a second person had simply read the questions and checked the answers UPDATE I have passed the ICND1 test If you study the material in this book, use the commands, and practice setting up equipment you will pass I don t have physical hardware, all i used was packet tracer simulation software Just keep in mind that the questions at the end of the chapters are often wrong Always question the information if doesn t quite make sense and try to look it up online Also, i m happy to report i dont remember any questions in the test as vague as in the book especially chapter 1. Passed my CCNA reading this book in 2000, and preparing for the 2010 CCNA using the same revised revision of the same book.It covers all the aspects of the CCNA both ICND1 and ICND2 are good value for money. Preso da solo, questo libro serve a poco o nulla per studiare la CCNA questo perch andrebbe studiato insieme a un corso o a tanta pratica su strumenti veri per apprendere correttamente i concetti che vengono spiegati a volte anche fin troppo frettolosamente Se sapete l inglese abbastanza bene un must per la certificazione. The book arrived in excellent condition and within only a few days instead of within 14 days This was sooner than I expected since I did not put a rush on it and the free shipping to students with an edu account really helps lower the cost Throughout the book complex terminology in computers is explained in a clear manner with pictures to explain in detail what the different network devices look like The review questions in the back of each chapter are extremely useful Originally I missed half of the information covered in the review questions and after rereading information throughout the chapter to answer the review questions, I became better prepared for class rereading the material and discovering the relevant information within the chapter that I was missing.I was able to easily check my answers through the appendix at the back of the book, rather than waiting for the instructor to verify whether the answers are correct.Even if you are not taking a networking class, if you want to understand the basics of TCP IP, Ethernet LANs, Wireless LANs,subnetting, and how routers, switches, and servers work together on the network, I highly recommend this book and highly recommend that you use this seller The seller sold it to me at a very good price, which is a great investment in my education. I purchased this book towards preparation for the CCNA exam, and for my own learning purposes, to help me inconfiguring my own network set ups and installations.I liked it so much, its clarity and detail, that I enrolled at SUNY Farmingdale, Cisco Networking Academy andComputer Science Dept to learn even , and prepare myself for a new trade or occupation as a computer net working technician with website programming, design and maintainence as a minor I already am a hardware andelectronic technician, and this would round out my skill set and enable me to achieve my goals.I recommend this book to anyone who wants to learn the nuts and bolts of computer networking, exam or not Itwill be money well spent by you if you can apply the concepts in the real world, at home and or elsewhere.

Obviously the person writing the material did not bother to create the quizes There are dozens of errors if not I trusted in myself and took the test anyway.I failed with a 70% no because I didn t know the material, it was my fist Cisco test and wasn t speedy enough with the subnetting The author should have really stressed how important timing was and at least gave a summary of what the official test was like and gave some tips.I would not recommend buying this book, other than for reference for a newbie.
