"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 14-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 17-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

Table 17-1. "Do I Know This Already?" Foundation Topics Section-to-Question Mapping

Foundation Topics Section	Questions Covered in This Section
Understanding the Fundamentals of Redistribution	14
Understanding the Routing Decisions That Affect Redistribution	5, 6
Controlling Routing Updates During Redistribution	7
Configuring Redistribution	811
Controlling Routing Updates with Filtering	12, 13
Verifying, Maintaining, and Troubleshooting the Implementation of Redistribution and Filtering	14

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 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.

1:	Which of the following are reasons to run multiple routing protocols? Applications requiring UNIX Smaller routing domains speed up convergence Political enclaves Smaller routing domains ensure a more stable network
2:	EIGRP automatically redistributes into which routing protocols? IGRP running the same AS number IGRP with any process ID EIGRP running the same AS number EIGRP with any process ID
3:	What do the letters SIN represent? Simple Internetwork Ships in the night Structured IP Network Single IP Network
4:	How many IP routing tables can be held on a router within a typical organization? One One per routing protocol Four Six
5:	The problems experienced as a result of multiple routing processes and their redistribution include which of the following? Suboptimal path Loss of Hello packets Routing loops Continuous LSA propagation
6:	What action is taken if no seed or default metric is configured for OSPF when redistributing EIGRP? The route is not entered into the routing table. The route is entered with a cost of 0. The route is read into OSPF with a cost of 20 (type E2). The route is entered with a cost of 20 (type 1).
7:	What techniques can be employed to avoid redistribution problems? Distribute lists Change administrative distance Ensuring the default metric is set to 0 Redistributing on all border routers in both directions
8:	What is the purpose of distribute lists? Determine the administrative distance of a distributed routing protocol Identify which interfaces will send updates Determine which networks are sent in updates Determine which networks are accepted into the routing table
9:	Where are distribute lists defined? At the interface Under the routing process At the router level At the executive prompt
10:	Which command is used to establish the default or seed metric for EIGRP? default-metric 5 metric bandwidth delay reliability loading mtu default-metric bandwidth delay reliability loading mtu eigrp default-metric bandwidth delay reliability loading mtu
11:	Which command is used to configure the administrative distance? administrative distance distance ip default-distance ip administrative distance
12:	Why might it be necessary to control the routing updates? Security Prevention of routing loops Scaling the network Preserving the metric
13:	All of the following statements are true; however, which of the following actions is taken first? Do not advertise the route if it is matched by a deny statement. If no match is found in the distribute list, the implicit deny any at the end of the access list will cause the update to be dropped. If a filter is present, the router examines the access list to see if there is a match on any of the networks in the routing update. Advertise the route if matched by a permit statement.
14:	Which commands could be used to verify and troubleshoot a network that is redistributed? show ip protocol show ip route show ip route routing-protocol show redistributed

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.

• 811 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."

• 12 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.
