Goals and Methods
The goal of this book is to assist you in learning and understanding the technologies
covered in the Network+ N10-006 blueprint from CompTIA. This also allows you

Network+ exam.
To aid you in mastering and understanding the Network+ certification objectives,
this book uses the following methods:
■ Opening topics list: This defines the topics that are covered in the chapter.
■ Foundation topics: At the heart of a chapter, this section explains the topics
from a hands-on and a theory-based standpoint. This includes in-depth descriptions,
tables, and figures that build your knowledge so that you can pass
the N10-006 exam. The chapters are each broken into multiple sections.
■ Key topics: This indicates important figures, tables, and lists of information
that you need to know for the exam. They are sprinkled throughout each
chapter and are summarized in table format at the end of each chapter.
■ Memory tables: You can find these on the DVD within Appendixes D and E.
Use them to help memorize important information.
■ Key terms: Key terms without definitions are listed at the end of each chapter.
Write down the definition of each term, and check your work against the
complete key terms in the Glossary. On the DVD, you will find a flash card
application with all the glossary terms separated by chapter, so feel free to use
that to study key terms as well.
■ Exercises: This book comes with 40 performance-based practice exercises that
are designed to help you prepare for the hands-on portion of the Network+
exam. These exercises are available on the DVD. Make sure you do the exercises
as you complete each chapter and again when you have completed the
