Acknowledgments
There are many people who 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.
Kenyon Brown, my acquisitions editor, is instrumental to my success in the world of Cisco
certification. Ken, I look forward to our continued progress together in both the print and video
markets! My technical editor, Todd Montgomery, was absolutely amazing to work with and he
was always there to check my work and make suggestions. Thank you! Also, I've worked with
Kim Wimpsett, the development editor, for years now and she coordinated all the pages you hold
in your hands as they flew from thoughts in my head to the production process.
Christine O'Connor, my production editor, and Judy Flynn, my copyeditor, were my rock and
foundation for formatting and intense editing of every page in this book. This amazing team gives
me the confidence to help keep me moving during the difficult and very long days, week after
week. How Christine stays so organized with all my changes as well as making sure every figure is
in the right place in the book is still a mystery to me! You're amazing, Christine! Thank you! Judy
understands my writing style so well now, after doing at least a dozen books with me, that she
even sometimes finds a technical error that may have slipped through as I was going through the
material. Thank you, Judy, for doing such a great job! I truly thank you both.
