Acknowledgments

When we wrote the first edition of the CWNA Study Guide, David Coleman's children, Brantley and Carolina, were young teenagers. Carolina now holds a master's degree in public policy from the University of Southern California (USC). Brantley graduated from Boston University and recently earned his Ph.D. in biochemistry at the University of Washington. David would like to thank his now adult children for years of support and for making their dad very proud. David would also like to thank his mother, Marjorie Barnes, stepfather, William Barnes, and brother, Rob Coleman, for many years of support and encouragement. David also thanks Valla Ann for being so special and making him laugh sideways.

David Coleman would also like to thank his friends and family at Aerohive Networks (www.aerohive.com). There are many past and present Aerohive employees he would like to thank, but there simply is not enough room. So thank you to all of his Aerohive co-workers. It has been one wild ride the past nine years!

David Westcott would like to thank Janie and Savannah for the smiles and hugs he receives when arriving home after being away delivering a training class. He would also like to thank Janie for her patience and understanding of his travel and writing demands.

David Westcott also would like to thank the training department at Aruba Networks. In 2004 Aruba Networks hired him as their first contract trainer. Much has changed over the years, but it is still a fun and exciting journey.
