Acknowledgments

There are many people that work to put a book together, and as an author, I dedicated an enormous amount of time to write this book, but it would have never been published without the dedicated, hard work of many other people.

Monica Worthy Lammle was crucial to the finished product this book became, going over every word of every chapter with me to fine-tune the language and grammar. Without Monicas support in all areas of my life, Id never have finished writing this book.

Next in line to thank is my new technical editor, John Swartz, who also coauthored the CCNA Data Center study guides with me. His expertise in the Cisco technical field, and his history of networking in general, is second to none. His detailed analysis of my work helped make this my best CCNA study guide ever. Thank you, John, for working hard under pressure, with tight deadlines, and for staying the course of delivering high-quality work in a short time frame.
