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 12-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 1-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

Understanding Routing Protocol Fundamentals


Types of Routing Protocols


The Routing Table


Routing Versus Switching



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.


Which of the following criteria would select a route as the preferred path to a destination network to be added to the routing table?

  1. The route is the only available path to the destination network.

  2. The route has one interface configured for IP.

  3. The route has the lowest administrative distance.

  4. The route has the lowest metric.


Which of the following best describes a routing protocol?

  1. A set of rules that describes how Layer 3 routing devices will send updates between each other about available networks and build a routing table

  2. The mechanism by which a router describes the autonomous system

  3. The means by which a router learns about the Internet

  4. The rules that state how a router builds a routing table


What is the forwarding process?

  1. The means by which a datagram is selected to be in the routing table

  2. The process that determines which path to select from the routing table

  3. How networks are forwarded between autonomous systems

  4. The switching process using the memory cache


What is the purpose of the command ip classless ?

  1. To force a classful routing protocol to send the subnet mask in its routing updates

  2. To allow VLSM to be configured on directly connected interfaces

  3. To allow the redistribution of OSPF subnets into RIPv1

  4. To allow the router to ignore the classful boundaries of the networks in its routing table and simply route to the longest prefix match it can find


Which of the following statements characterizes classless routing protocol?

  1. Within the same IANA classful network address, subnets are exchanged between the routers without the subnet mask.

  2. Router interfaces using the same IANA classful network address can have different subnet masks.

  3. IGRP and EIGRP are the only distance vector routing protocols that can be configured as classless routing protocols.

  4. Within the same IANA classful network address, subnets are exchanged between the routers.


Which of the following two statements is a characteristic of a classful routing protocol?

  1. Routes exchanged between foreign networks are summarized to the IANA classful address.

  2. Within the same network (IANA network number), different subnet masks can be configured.

  3. All the interfaces on all the routers within an IANA network number must share the same subnet mask.

  4. All interfaces on a router must share the same subnet mask.


Which of the following is an instance of when a static route is used?

  1. On a slow speed dialup link

  2. On networks where surge protectors are not in use

  3. When there are many links to the Internet

  4. On unstable networks


What does signify in an IP routing table?

  1. Indicates the router whose routing table is being displayed

  2. Indicates that the router has no directly connected interfaces

  3. Indicates that no routing protocol is running

  4. Shows the default route for the routing table


What is the command syntax to empty the Cisco routing table of all its routes?

  1. clear ip route *

  2. clear ip route table

  3. reset ip route *.*.*.*

  4. clear ip route


Cisco makes a distinction between the routing function and the switching function of a router. Which of the following best describes the routing function?

  1. Moving data to the end destination that is in cache

  2. Load balancing

  3. Moving the datagram across the router

  4. Path determination


What information is found in the routing table in order to process switch a packet?

  1. The address of the neighboring router that will forward the traffic

  2. The MAC address of the remote network

  3. The destination address of a static route

  4. The path with the lowest administrative distance


Which of the following questions are asked by the routing function when trying to route a datagram?

  1. If the destination network is not in the routing table, is there a default network configured?

  2. Is fast switching enabled?

  3. Which is the best path to that remote network?

  4. Are there multiple equal-cost paths?

The answers to the "Do I Know This Already?" 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" and "Foundation Summary" sections, the "Q&A" section, and the "Scenarios" at the end of the chapter.

  • 79 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."

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