From the Library of Samuel Vincent Mickens ptg7538860 vi CCENT/CCNA ICND1 640-822 Official Cert Guide Dedication For Hannah Odom, the best daughter I could ask for. I love you, my girl! From the Library of Samuel Vincent Mickens ptg7538860 vii Acknowledgments You know, after writing books for 13 years now, I would think that there would be something normal, something repetitive, and that each book would pretty much follow the same process as others. It now seems that normal is actually abnormal, and that requires everyone to think outside the box. More so than probably any other editions of these books, these books really are the result of a team effort. The biggest news relates to all the extras Cisco Press added to the package. Thanks to Dave, Brett, Kourtnaye, Sandra, and all the folks at Cisco Press for going several extra miles to make this “extra” edition happen, and with so many extra valuable pieces. I think the readers will appreciate the added value. Now, on to the specifics. First, my hat’s off to Drew Cupp. Wow. Between this book, the matching ICND2 Official Cert Guide, and another title, Drew and I went from having no books to working on three together all at once. And they all fell into the same 5-month stretch from start to finish. It makes my head hurt thinking about it. Besides taking on extra work to get it done, Drew’s clarity of thought about how to get from here to there through the process, with so many different print, DVD, and online elements, wow—no way this book gets done without Drew. Thanks, Drew: You da man! Brian, Teri, and Steve all did a great job technical editing the book. Besides helping find mistakes and keeping the book accurate, each tech editor brought a different perspective to the process. I hope we can work together on future editions. And a special thanks to Elan Beer, the best tech editor in the business, for working on the new materials for this edition. You know, it’s great when the person you rely on most at work is consistently helpful and always comes through, whether working on an opportunity or an issue. But, when that person actually works for a partner company, it’s all the more impressive. I am fortunate enough to have such an ally in Brett Bartow—thank you so much for walking this journey with me. Mandie Frank gets the “hot potato” award for working as the project editor with this book and with ICND2. The nature of this project plus the ICND2 book at practically the same time can create some challenges. Mandie handled them all with grace and aplomb, and she seamlessly managed the entire process with the rest of the production team. Thanks, Mandie, and the whole group! And thanks especially for the extra attention to the pages review. Thanks to Richard Bennett, who slaved on a short schedule on some figure improvements that I really wanted to include in this book and for his work on the question database. Dude, Robin Williams would be proud! From the Library of Samuel Vincent Mickens ptg7538860 viii CCENT/CCNA ICND1 640-822 Official Cert Guide A special thank you goes to you readers, who write in with suggestions, possible errors, and especially those of you who post online at the Cisco Learning Network (CLN). Without question, the comments I receive directly and overhear by participating at CLN made this edition a better book. Finally, thanks to my wife Kris for all her support with my writing efforts, her prayers, and understanding when the deadline didn’t quite match with our vacation plans this summer. (Yes, that’s twice in a row that when this book revved, we cancelled vacation—you’re a doll!) And thanks to Jesus Christ—all this effort is just striving after the wind without Him.
