58 Chapter 2: Cisco Internetwork Operating System (IOS) Fundamentals
Q&A
As mentioned in Chapter 1, 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.
Make sure to use the CD and take the simulated exams.
The answers to these questions can be found in Appendix A, on page 703.
