First, a loud callout to Jim Frye, who was instrumental in putting this book together. He spent countless hours combining and summarizing my work from the CCENT and CCNA ICND2 study guides into what is a really nice review guide for the CCNA Routing and Switching certification. Thank you, Jim!

Thanks to Jeff Kellum, who always keeps me working hard and makes sure I am headed in the right direction. This is no easy task for Jeff!

And thanks to my production editor, Eric Charbonneau, for keeping the book on track, and Amy Breguet, for keeping all the edits in order and on time. And I cant forget Judy Flynn, the backbone of all my books, who reads every word over and over until the chapters are nearly flawless!

Last, thanks to Isaac Valdez, my tech editor for this edition of the review guide.

Thank you all!
