Do I Know This Already? Quiz

"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 11-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 5-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

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 provide you with a false sense of security.

10.	If a switch port is in the errdisable state, what is the first thing you should do? Reload the switch. Use the clear errdisable port command. Use the shut and no shut interface-configuration commands. Determine the cause of the problem.
11.	Which of the following show interface output information can you use to diagnose a switch port problem? Port state. Port speed. Input errors. Collisions. All of these answers are correct.

You can find the answers to the quiz 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:

• 7 or less overall scoreRead the entire chapter. This includes the "Foundation Topics," "Foundation Summary," and "Q&A" sections.
  
  
• 89 overall scoreBegin with the "Foundation Summary" section and follow up with the "Q&A" section at the end of the chapter.
  
  
• 10 or more overall scoreIf 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 to Chapter 6, "VLANs and Trunks."
