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.
