You can find the answers to the following questions in Appendix A, "Answers to Chapter Review Questions."

1:

Compare and contrast the terms "physical LAN" and "broadcast domain."

2:

Define the term "broadcast domain."

3:

What happens to a broadcast frame when a hub or a switch receives it?

4:

Imagine a standalone switch with no VLANs configured, with 24 physical ports, each connected to a different PC. How many broadcast domains exist?

5:

Imagine that a 12-port switch has 11 PCs connected to it, with the twelfth port connected to a hub. The hub has four PCs connected to it as well. The switch does not have VLANs configured. How many broadcast domains exist?

6:

Define the term "VLAN."

7:

What is the key difference between a physical LAN and a VLAN, according to this chapter?

8:

Imagine that three VLANs were created on a single switch. The switch receives a broadcast into a port in VLAN1. Will devices in VLAN2 receive the broadcast?

9:

Imagine that three VLANs were created on a single switch. The switch in a port in VLAN1 received a unicast frame sent to MAC address 0200.5555.555. The VLAN1 address table in the switch does not have an entry for that MAC address. What will the switch do with this frame?

10:

Imagine that three VLANs were created on a single switch. A unicast frame, sent to MAC address 0200.5555.555, was received by the switch in a port in VLAN1. The VLAN2 MAC address table lists an entry for 0200.5555.5555, referencing port 18. What will the switch do with this frame?

11:

List two reasons why a network engineer might want to use VLANs.

12:

Imagine one LAN with 100 devices, and another with 1000 devices. Explain the similarities and differences of the impact of broadcasts in each LAN.

13:

Compare and contrast physical LANs and virtual LANs.

14:

Imagine that two switches are connected with an Ethernet cable. Three VLANsVLAN1, VLAN2, and VLAN3are configured on each switch. Name the two trunking protocols that could be used on the segment between switches and explain their basic operation.

15:

Imagine that two switches are connected with an Ethernet cable. No VLANs are configured. Describe the meaning of the term "trunk," and tell whether a trunk is needed or used in this small network.

16:

Identify the two VLAN trunking protocols and state which is Cisco proprietary.
