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 to 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 17-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 18-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

Questions Covered in This Section

Understanding Route Maps


Understanding Policy-Based Routing


The Operation of Route Maps and Policy-Based Routing

Monitoring the Configuration of Route Maps, Policy-Based Routing, and Redistribution



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.


In what ways are route maps more sophisticated than access lists?

  1. Access lists can change the destination address of the outbound data packet.

  2. Route maps take less CPU because of streamlined processing.

  3. Access lists either exclude or include, whereas route maps can change the characteristics of the path .

  4. Access lists can only be applied on inbound updates.


Route maps can be used for which of the following applications?

  1. NAT

  2. BGP

  3. Summarization

  4. Redistribution


Which of the following best describe a match statement?

  1. The means by which a route is selected

  2. A list of selection criteria

  3. The method of discarding unwanted packets

  4. A list of network prefixes


Which of the following best describe a set statement?

  1. The method used to determine the best metric

  2. The means of choosing the next hop

  3. A list of conditions to apply to chosen routes

  4. The means of changing routes or packets that are matched


Many match statements can be used in a route map. How many match statements must be matched for the set to be applied?

  1. At least one

  2. All of the criteria

  3. None of them

  4. At least 50 percent of the criteria


What are some of the benefits of policy-based routing?

  1. The ability to link extended access lists

  2. Easy administration

  3. QoS

  4. Load balancing


What is the relationship between route maps and policy-based routing?

  1. Route maps use policy-based routing.

  2. Route maps and policy-based routing are interchangeable terms.

  3. Policy-based routing uses route maps.

  4. Policy-based routing works with access lists, whereas route maps use a programming language.


Policy-based routing is applied to what type of traffic?

  1. Inbound and routed traffic dependent on the configuration

  2. Incoming packets

  3. The routing process

  4. Transiting traffic


If no match is made in a policy-based routing list of criteria, what action is taken?

  1. The packet is sent to null interface 0.

  2. The packet is dropped and no ICMP packet is sent to the source.

  3. The packet is dropped and an ICMP packet is sent to the source.

  4. The packet is sent to the routing process.


What additional configuration is required to ensure that packets are dropped when matched to a deny statement?

  1. The set command at the end of the route map should be a static route to null 0.

  2. The deny statement should be set to

  3. The last set command should be configured to the no-forward parameter.

  4. No extra configuration is required, because packets that are denied are automatically dropped.


What command is used to match a packet based on its size ?

  1. match length

  2. match size

  3. match MTU

  4. match ip length


Which set command is used only when there is no route found in the routing table?

  1. set ip next hop

  2. set default next hop

  3. set ip default next-hop

  4. set default gateway


What command is used to configure fast switching for route maps?

  1. No command is required, because fast switching is on by default

  2. Router(config-route-map)# set fast-switch on

  3. Router(config-if)# ip route-cache policy

  4. router# enable fast-switching


When using route maps for redistribution when there is a match and the deny statement is configured, what action will be taken by the route map?

  1. The packet is dropped.

  2. The route is not redistributed.

  3. An ICMP packet is sent to the sender.

  4. The packet is sent to the normal routing process.


How are the services of the route map for redistribution called?

  1. The route map command

  2. Under the incoming interface

  3. The redistribution command

  4. As a global configuration command


Which command is useful for validating the path to the destination with a specified packet size?

  1. Extended ping

  2. show ip protocol

  3. show ip route

  4. show redistribution


Which command is used to show the configured route maps?

  1. show ip route map

  2. show route-map

  3. show ip map

  4. show ip policy
