Introduction IntroductionYou are almost there! If you're reading this Introduction, you've probably already spent a considerable amount of time and energy pursuing your CCNA certification. Regardless of how you got to this point in your travels through your CCNA studies,31 Days Before Your CCNA Exammost likely represents the last leg of your journey on your way to the destination: to become a Cisco Certified Network Associate. However if you are like me, you might be reading this book at thebeginningof your studies. If such is the case, this book provides you with an excellent overview of the material you must now spend a great deal of time studying and practicing. I must warn you, though; unless you are extremely well versed in networking technologies and have considerable experience configuring and troubleshooting Cisco routers and switches, this book willnotserve you well as the sole resource for CCNA exam preparation. Therefore, let me spend some time discussing my recommendations for study resources. Study ResourcesCisco Press offers an abundance of CCNA-related books to serve as your primary source for learning how to install, configure, operate, and troubleshoot medium-size routed and switched networks. See the inside cover of this book for a quick list of my recommendations. Foundational ResourcesFirst on the list must be Wendell Odom'sCCNA Official Exam Certification Library, Third Edition (ISBN: 1587201836). If you do not buy any other books, buy this set of two. Wendell's method of teaching, combined with his technical expertise and down-to-earth style, is unsurpassed in our industry. As you read through his books, you sense that he is sitting right there next to you walking you through the material. The practice exams and study materials on the CD in the back of the book are worth the price of the book. There is no better resource on the market for a CCNA candidate.Next on the list must be Steve McQuerry'sAuthorized Self-Study Guide CCNA Preparation Library, Seventh Edition (ISBN: 1587054647). These two books are indispensable to those students who take the two Cisco recommended training classes for CCNA preparation: Interconnecting Cisco Network Devices 1 (ICND1) and Interconnecting Cisco Network Devices 2 (ICND2). These courses, available through Cisco Training Partners in a variety of formats, are usually of a very short duration (1 to 6 weeks) and are geared toward the industry professional already working in the field of networking. Steve's books serve the reader well as a concise, but thorough, treatment of the CCNA exam topics. His method and approach often differ from and complement Wendell's approach. I recommend that you also refer to these books.If you are a Cisco Networking Academy student, you are blessed with access to the online version of the CCNA curriculum and the wildly popular Packet Tracer network simulator. Although there are two versions of the CCNA curriculum--Discovery and Exploration--I chose to use the four CCNA Exploration courses in my daily review of the exam topics. The Exploration curriculum provides a comprehensive overview of networking, from fundamentals to advanced applications and services. The Exploration courses emphasize theoretical concepts and practical application, while providing opportunities for students to gain the skills and hands-on experience needed to design, install, operate, and maintain networks in small-to-medium businesses, as well as enterprise and service provider environments. In an Academy class, not only do you have access to Packet Tracer, but you have access to extensive, guided labs and real equipment on which to practice your CCNA skills.
