      First, a loud callout to Troy McMillan, who was instrumental in putting this book together. He spent countless hours combining and summarizing my work from the CCENT and CCNA ICND2 study guides into what is a really nice review guide for the CCNA Routing and Switching certification. Thank you, Troy!

      Thanks to Ken Brown, who always keeps me working hard and makes sure I am headed in the right direction. This is no easy task for Ken!

      And thanks to my production editor, Christine O'Connor, for keeping the book on track, and Amy Breguet, for keeping all the edits in order and on time. And I can't forget Judy Flynn, the backbone of all my books, who reads every word over and over until the chapters are nearly flawless!

      Thank you all!

      Introduction

      Welcome to the exciting world of Cisco certification! If you've picked up this book because you want to improve yourself and your life with a better, more satisfying, and secure job, you've done the right thing. Whether you're striving to enter the thriving, dynamic IT sector or seeking to enhance your skill set and advance your position within it, being Cisco certified can seriously stack the odds in your favor to help you attain your goals!

      Cisco certifications are powerful instruments of success that also markedly improve your grasp of all things internetworking. As you progress through this book, you'll gain a complete understanding of networking that reaches far beyond Cisco devices. By the end of this book, you'll comprehensively know how disparate network topologies and technologies work together to form the fully operational networks that are vital to today's very way of life in the developed world. The knowledge and expertise you'll gain here is essential for and relevant to every networking job and is why Cisco certifications are in such high demand – even at companies with few Cisco devices!

      Although it's now common knowledge that Cisco rules routing and switching, the fact that it also rocks the voice, data center, and service provider worlds is also well recognized. And Cisco certifications reach way beyond the popular but less extensive certifications like those offered by CompTIA and Microsoft to equip you with indispensable insight into today's vastly complex networking realm. Essentially, by deciding to become Cisco certified, you're proudly announcing that you want to become an unrivaled networking expert – a goal that this book will get you well on your way to achieving. Congratulations in advance on the beginning of your brilliant future!
