Q & A
The Q & A questions are more difficult than what you can expect 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 retain the material. Rather than allowing you to derive the answer from clues hidden
inside the question itself, these questions challenge your understanding and recall of the subject.
Questions from the “Do I Know This Already?” quiz are repeated here to ensure that you have
mastered the chapter's topic areas. A strong understanding of the answers to these questions
will help you on the CCIE written exam. As an additional study aide, use the CD-ROM
provided with this topic to take simulated exams.
Select the best answer. Answers to these questions are in the Appendix, “Answers to Quiz
Questions.”
