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 what parts of this chapter to use. If you already intend to read the entire chapter, you do not necessarily need to answer these questions now.

The 15-question quiz, derived from the major sections in the "Foundation Topics" portion of the chapter, helps you to 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.

Link-State Routing Protocol Overview











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 for purposes of the self-assessment. Giving yourself credit for an answer you correctly guess skews your self-assessment results and might provide you with a false sense of security.

When an OSPF router receives an LSA, which of the following best describes the action taken?

  1. Update the routing table and flood the new routing table out of all interfaces

  2. Update the topology table and flood the LSA out of its interfaces

  3. Put the suspect route into holddown for 30 seconds

Which of the following routing protocols runs the Dijkstra algorithm to rebuild the routing table?

  1. IS-IS

  2. EIGRP

  3. BGP

  4. OSPF


When a neighbor is no longer available, what action will the BGP router take?

  1. Clears the route from the routing table and floods a LSA out of all interfaces

  2. Queries neighbors for a new route

  3. Uses a holddown of 30 seconds

  4. Tries to reconnect to its neighbor

The answers to this 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 :

  • 7 or less overall score Read the entire chapter. This includes the "Foundation Topics" and "Foundation Summary" sections, the "Q&A" section, and the "Scenarios" at the end of the chapter.

  • 810 overall score Begin with the "Foundation Summary" section, and then go to the "Q&A" section and the "Scenarios" at the end of the chapter. If you have trouble with these exercises, read the appropriate sections in "Foundation Topics."

  • 11 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 and the "Scenarios" at the end of the chapter. Otherwise, move to the next chapter.
