From Jeremy: I’d like to dedicate this book to my newest daughter, Isabella She’s currently six

months old and is staring at me right now from a soft blanket on the floor By the time she’s old enough to read this, this book will probably be outdated as we will all have Ethernet ports implanted

in our skull (I’m opting for a wireless connection, myself) Hopefully, if we remember to pull this book off the shelf and read this dedication I can tell her what amazing joy she has brought me This tiny, arm flailing, cooing, cheesy-grinning, soft, delicate, playful, yet scandalously sly, giggling little girl has become my addiction I hope I can always help her know how incredibly special she is to me.

From Dave: This book is dedicated to my soon-to-be daughter, Chloe By the time this book is

print-ed, you will be born and your exquisite mother and I can have longwinded debates about which event was more distressing I very well may have written books about Cisco technology and whatnot, but as

for incredible blessings, it’s you who wrote the book.

From Heather: I would like to dedicate this book to anyone and everyone who has ever helped me in

my pursuit to learn I have been fortunate enough to have many wonderful teachers in my life Not just school teachers, but family and friends who have given me their hand along the way.

From Jeremy: My number one acknowledgment always goes to God who has blessed me in

more ways than I even realize Thank you for granting me the talent to be successful in therealm of Cisco networking Please allow me to use these talents to accomplish more for Yourkingdom than an Ethernet cable ever could Thanks to my darling wife, Susan You are myeyes and ears that help me to see what is REALLY going on around me I love you! And last,but not least: Thank you fish swimming in the big fish tank next to me You bring me muchpeace and serenity as I sit here typing these acknowledgments Especially the big yellowButterfly fish that swims this way and that Swish, swish, swish Swish, swish

From Dave: As always, I would like to put to paper yet again my undying gratitude and love

to my wife, Marsha Your beautiful spirit outshines the sun even on the brightest of days I alsowould like to thank my family and family-in-laws for your unwavering support I especiallywant to honor my mother-in-law, Pattie, who touched so many throughout her life Wordscannot fill the sorrow in our hearts, but your memories and spirit give us strength We willmiss you

From Heather: I would like to send out a huge hug and thank you to my parents and my

Dustin Dustin has been by my side for as long as I have been working in this industry He eventook me to my junior prom many, many years ago His support is immeasurable I am so lucky

to have amazing people around me to keep me sane Finally, DYB Bear and Grumpy Nigel alsodeserve a special hello Hello!

The Cisco Certified Network Associate (CCNA) accreditation has become the leading ductory-level network certification available today The CCNA certification is recognized byemployers as providing candidates with a solid foundation of Cisco networking concepts, ter-minology, and skills The CCNA exam covers a broad range of networking concepts to preparecandidates for the technologies they are likely to work with in today’s network environments.This book is your one-stop shop Everything you need to know to pass the exam is in here.You do not have to take a class in addition to buying this book to pass the exam However,depending on your personal study habits or learning style, you might benefit from buying this

intro-book and taking a class Taking a CCNA certification class gives you dedicated study time and

precious hands-on experience with live Cisco equipment

Exam Preps are meticulously crafted to give you the best possible learning experience for the

particular characteristics of the technology covered and the actual certification exam The

instructional design implemented in the Exam Preps reflects the task- and experience-based nature of Cisco certification exams The Exam Preps provide the factual knowledge base you

need for the exams and then take it to the next level, with exercises and exam questions thatare required in the CCNA certification

Cisco has split the single CCNA test into two separate exams, ICND1 and ICND2 Althoughthe single CCNA exam still remains, Cisco recommends that only those who are recertifying

an existing CCNA certification take this exam This CCNA Exam Prep title prepares you for

both the ICND1 exam, which covers the foundational Cisco network concepts andconfigurations, and the ICND2 exam, which covers the more advanced network concepts andconfigurations Personally, we recommend that you follow Cisco’s advice on taking the two-exam path rather than the single CCNA exam Although it may be tempting to go after theone-test “fast-track,” this single exam is extremely difficult and has discouraged many poten-tial CCNA candidates from continuing on their Cisco certification journey

How This Book Helps You

This book takes you on a self-guided tour of all the areas covered by the CCNA exam andteaches you the specific skills you need to achieve your certification This book also containshelpful hints, tips, real-world examples, and exercises, as well as references to additional studymaterials Specifically, this book is set up to help you in the following ways:
