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 quiz, derived from the major sections in the "Foundation Topics" portion of the chapter, helps you determine how to spend your limited study time.

Table 10-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

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


1.

Where should the Root Bridge be placed on a network?

  1. On the fastest switch

  2. Closest to the most users

  3. Closest to the center of the network

  4. On the least-used switch

2.

Which of the following is a result of a poorly placed Root Bridge in a network?

  1. Bridging loops form.

  2. STP topology can't be resolved.

  3. STP topology can take unexpected paths.

  4. Root Bridge election flapping occurs.

3.

Which of these parameters should you change to make a switch become a Root Bridge?

  1. Switch MAC address

  2. Path cost

  3. Port priority

  4. Bridge priority

4.

What is the default 802.1D STP bridge priority on a Catalyst switch?

  1. 0

  2. 1

  3. 32,768

  4. 65,535

5.

Which of the following commands is most likely to make a switch become the Root Bridge for VLAN 5, assuming that all switches have the default STP parameters?

  1. spanning-tree root

  2. spanning-tree root vlan 5

  3. spanning-tree vlan 5 priority 100

  4. spanning-tree vlan 5 root

6.

What is the default path cost of a Gigabit Ethernet switch port?

  1. 1

  2. 2

  3. 4

  4. 19

  5. 1000

7.

What command can change the path cost of interface Gigabit Ethernet 3/1 to a value of 8?

  1. spanning-tree path-cost 8

  2. spanning-tree cost 8

  3. spanning-tree port-cost 8

  4. spanning-tree gig 3/1 cost 8

8.

What happens if the Root Bridge switch and another switch are configured with different STP hello timer values?

  1. Nothingeach sends hellos at different times.

  2. A bridging loop could form because the two switches are out of sync.

  3. The switch with the lower Hello timer becomes the Root Bridge.

  4. The other switch changes its Hello timer to match the Root Bridge.

9.

What network diameter value is the basis for the default STP timer calculations?

  1. 1

  2. 3

  3. 7

  4. 9

  5. 15

10.

Where should the STP PortFast feature be used?

  1. An access-layer switch port connected to a PC

  2. An access-layer switch port connected to a hub

  3. A distribution-layer switch port connected to an access layer switch

  4. A core-layer switch port

11.

Where should the STP UplinkFast feature be enabled?

  1. An access-layer switch

  2. A distribution-layer switch

  3. A core-layer switch

  4. All of the above

12.

If used, the STP BackboneFast feature should be enabled on which of these?

  1. All backbone- or core-layer switches

  2. All backbone- and distribution-layer switches

  3. All access-layer switches

  4. All switches in the network

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:

  • 10 or less overall score Read the entire chapter. This includes the "Foundation Topics," "Foundation Summary," and "Q&A" sections.

  • 11 or 12 overall score If you want more review on these topics, skip to the "Foundation Summary" section and then go to the "Q&A" section at the end of the chapter. Otherwise, move to Chapter 11, "Protecting the Spanning Tree Protocol Topology."
