Sybex is proud to have helped thousands of i-Net+ candidates prepare for their exam, and we are excited about the opportunity to continue to provide people with the skills they’ll need to succeed in the highly competitive IT industry. CompTIA recently revised the i-Net+ exam, updating the objectives set and expanding the question pool, all in an effort to prevent the dreaded paper-certification syndrome, where individuals obtain a certification without a thorough understanding of the technology. Sybex supports this philosophy, as we have always advocated a comprehensive instructional approach to certification courseware. It has always been Sybex’s mission to teach exam candidates how new technologies work in the real world, not to simply feed them answers to test questions. We’re especially excited about this second edition of our best-selling i-Net+ Study Guide, as it now sports the new CompTIA Authorized Quality Curriculum (CAQC) logo on the cover. CompTIA developed the CAQC program to help exam candidates make better decisions about which training materials to use, and has established rigorous standards that courseware developers must meet in order to display the CAQC logo. The book you hold in your hands went through a review process that checked for exam objective correlation and instructional design integrity, and we are happy to say that we passed with flying colors! We’re confident that this books will help you, the i-Net+ exam can- didate, succeed in your endeavors. Good luck in pursuit of your Network+ certification!

Everyone who worked on this book should be proud of the work they have done here. First, I would like to thank my co-author, Dorothy McGee. Thanks also to my technical editors, Andrew Barkl and Scott Warmbrand. They were responsible for making sure the information in this book is tech- nically accurate and as up-to-date as possible. This book would not have existed if not for the efforts of Elizabeth Hur- ley, this book’s developmental and acquisitions editor at Sybex. Thank you for putting up with all my phone calls and e-mails! Additionally, thanks go out Susan Hobbs and Judy Flynn for turning my collection of chicken- scratchings into a cohesive, useful study guide. The production department at Sybex also deserves my thanks. Thanks to Nila Nichols, electronic pub- lishing specialist, for making this book look the way it does; to Teresa Trego, production editor, for making the production end of things run so smoothly. I would also like to acknowledge my wife, family, and friends. My wife, Linda, tirelessly wrote and edited the appendices as well as kept me on the right track. She was a real trooper because she did it while taking care of our daughter, Alison. Thanks to Alison, too, for being fussy when I needed a break (or when she thought I needed a break) or cute when I needed a laugh. Thank you to my family and friends who understood when I couldn’t do something because I had to work on the book. I really appreciate that. Finally, I thank you, the reader, for purchasing this book. I know that it has all the information in it to help you pass the test. If you have questions about the i-Net+ exam or this book, feel free to e-mail me at dgroth@corpcomm .net. All us worked very hard on this book to make it the best i-Net+ study guide available. I hope you agree that it is. —David Groth So many people helped to bring this book to fruition, that it’s hard to know where to start. I would like to extend my whole-hearted thanks to David Groth and Elizabeth Hurley for the confidence and encouragement that both have given me during the production of this book. Many thanks go to Susan Hobbs who not only kept me on my toes during editing, but really lifted my spirits with her positive attitude throughout everything. I would also like to thank Teresa Trego for keeping me on track and ensuring that no stone was unturned during the whole process. Acknowledgments xi In addition to the wonderful folks at Sybex, I must acknowledge my hus- band, family, and friends. Darin, my husband, went beyond patience and understanding when I had to pass on chores or going places. His encourage- ment and much-needed advice when my brain performed a core-dump helped me get through. Many thanks to my mother, Sarah, and in-laws (Connie and Bud), who put up with my absences and lack of phone calls as I constantly lost track of time. I must also acknowledge Andy and John, my supervisors at work, who told me “go for it!” when the opportunity arose to work on this book and were patient on those days that I absolutely couldn’t work one minute late. Last but never least, I must thank you, the reader, who plunked down your hard-earned money for this book. Remember, this is the information age and knowledge IS power. Never stop learning, and never stop growing. If you have any questions or comments about the i-Net+ exam or the content in this book, please feel free to e-mail me at [email protected]. —Dorothy McGee
