Q&A
As mentioned in Chapter 1, "All About the Cisco Certified Network Associate Certification,"
the questions and scenarios in this book are more difficult than what you should experience on
the actual exam. The questions do not attempt to cover more breadth or depth than the exam;
however, they are designed to make sure that you know the answer. Rather than allowing you
to derive the answer from clues hidden inside the question itself, the questions challenge your
understanding and recall of the subject. Questions from the "Do I Know This Already?" quiz
from the beginning of the chapter are repeated here to ensure that you have mastered the
chapter's topic areas. Hopefully, these questions will help limit the number of exam questions
on which you narrow your choices to two options and then guess.
The answers to these questions can be found in Appendix A, on page 728.
