To Our Valued Readers:
CompTIA’s i-Net+ certification program has established itself as one of the leading general Internet
certifications in the IT industry. 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!

Acknowledgments
I
t takes many people to put a book together and this book is no excep-
tion. 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].
