"Do I Know This Already?" Quiz The purpose of the "Do I Know This Already?" quiz is to help you decide whether you need to read the entire chapter. If you already intend to read the entire chapter, you do not necessarily need to answer these questions now. The 12-question quiz, derived from the major sections in the "Foundation Topics" portion of the chapter, helps you determine how to spend your limited study time. Table 6-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics. Table 6-1. "Do I Know This Already?"

Caution The goal of self-assessment is to gauge your mastery of the topics in this chapter. If you do not know the answer to a question or are only partially sure of the answer, you should mark this question wrong. Giving yourself credit for an answer you correctly guess skews your self-assessment results and might give you a false sense of security.

The answers to the quiz are found in Appendix A, "Answers to Chapter 'Do I Know This Already?' Quizzes and Q&A Sections." The suggested choices for your next step are as follows: 6 or less overall score Read the entire chapter. This includes the "Foundation Topics," "Foundation Summary," and "Q&A" sections. 79 overall score Begin with the "Foundation Summary" section and then follow with the "Q&A" section at the end of the chapter. 10 or more overall score If you want more review on these topics, skip to the "Foundation Summary" section and then go to the "Q&A" section at the end of the chapter. Otherwise, move on to Chapter 7, "VLAN Trunking Protocol."
