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 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 7-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

Table 7-1. "Do I Know This Already?" Foundation Topics Section-to-Question Mapping

Foundation Topics Section

Questions Covered in This Section

Configuring OSPF in a Single Area


Configuring OSPF over an NBMA Topology


Checking the Configuration of OSPF on a Single Router


Troubleshooting OSPF in a Single Area



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.


At what level is the area for OSPF defined?

  1. Network

  2. Router

  3. Process

  4. Interface


Which of the following best define the purpose of the network command?

  1. To state the networks that are to be summarized

  2. To state the networks to be advertised

  3. To define the OSPF areas and associate the interface with the area

  4. To identify the interfaces through which OSPF packets are to be sent and received


Which of the following are valid network commands?

  1. network area 0

  2. network area

  3. network area 5

  4. network area


The default selection of the router ID would select a router ID by which of the following?

  1. Highest IP address

  2. Highest loopback address

  3. No defaults; must be manually configured

  4. Highest area ID, changing it to a dotted decimal notation


Which interface setting affects the default OSPF metric that is being run on a Cisco system?

  1. There is no default metric setting; it is an industry standard and must be manually configured.

  2. The error rate on the interface changes the cost of the link.

  3. The bandwidth setting changes the OSPF metric by default on Cisco routers.

  4. Changing the priority command changes the OSPF process, which affects the cost of the link.


Which best describes a loopback interface in OSPF?

  1. The loopback interface is used for testing the router.

  2. The loopback interface is a virtual interface that exists only in software.

  3. The loopback interface is an interface that has been terminated for troubleshooting.

  4. A loopback interface is an interface on FDDI.


When is the neighbor command used in configuring OSPF over a nonbroadcast NBMA link?

  1. Neighbors are defined to allow the manual configuration of the neighbor table.

  2. Nonbroadcast multiaccess ATM clouds need neighbors to be defined so that the address can be appended to each cell .

  3. In a nonbroadcast point-to-multipoint network, the neighbor command is used to define the next hop in OSPF.

  4. In a nonbroadcast environment, the DR and BDR must be configured with a static list of the other routers attached to the cloud so that they can become neighbors and create adjacencies.


Where would you configure a point-to-point interface for OSPF over an NBMA topology?

  1. At the interface level

  2. At the subinterface

  3. Under the routing process

  4. Under the subinterface


You use the broadcast mode to avoid using the neighbor command and all the attendant configurations. Which of the following commands is correct?

  1. ip ospf ptmp

  2. ip ospf point to point

  3. ip ospf network broadcast

  4. ip ospf broadcast


Which OSPF database is shown with the show ip ospf database command?

  1. Forwarding database

  2. Topology database

  3. Neighbor database

  4. SPF tree


Which of the following are shown in the command show ip ospf interface ?

  1. Link State Update Interval is 00:30:00

  2. Network Type broadcast

  3. Transmit delay is 1 sec

  4. Dead timer due in 00:00:34


Which of the following commands shows the DR?

  1. show ip ospf neighbor detail

  2. show ip ospf

  3. show ip ospf database

  4. show ip ospf interface


Which packets are shown in the command debug ip packet ?

  1. Discarded

  2. Received

  3. Generated

  4. Forwarded


Which debug command shows the changes in adjacencies, flooding information, designated router selection, and shortest path first (SPF) calculations?

  1. debug ip packets

  2. debug ip ospf events

  3. debug ospf events

  4. debug ospf packets

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 :

  • 8 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.

  • 911 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.
