What are the advantages of using VoIP compared to traditional phones? What are the
disadvantages?
What switch feature is often used when implementing VoIP?
What is the difference between the SIP and RTP protocols used with VoIP?
How do delay, jitter, and packet loss affect VoIP calls?
Why is Quality of Service (QoS) important for VoIP?
How does a switch identify devices that are in different VLANs?
What is required for devices to communicate between VLANs?
Which type of switch port is a member of all VLANs identified on the switch?
How are VLANs associated with frames as they move between switches?
How is port security different from port filtering?
What does port filtering use to control access?
When using 802.1x authentication, a device connected to an unauthenticated port can

communicate with which other devices on the LAN?
Which networking feature commonly uses VLANs?
What feature would you use to configure a device with two connections to the same
network?
What is the purpose of spanning tree in a switched network?
How does spanning tree compare to Ethernet bonding?
Why doesn't spanning tree provide improved performance?
How does a caching server improve network performance?
When should Quality of Service (QoS) be a major concern on your network?
What is the difference between a collision domain and a broadcast domain?
Your network uses only hubs as connection devices. What happens to the number of
collisions on the network as you add devices?
Which device provides guaranteed bandwidth between devices?
Which device can you use to filter broadcast traffic?
Your network uses only switches as connection devices. All devices have a dedicated
switch port. What happens to the number of collisions on the network as you add
devices?

Evaluation: Rubric, Lab Activity, Matching Assessment, Practical Application, Multiple Choice
Questionnaires:
Lab Activity:
In this lab, you will explore how VLAN membership affects device communications. The LAN is configured as shown
in the diagram, with all switch ports up and assigned to the default VLAN (VLAN1).
Tip: Print these instructions and record your answers as you complete each step. When you are finished, read the
feedback in the score report box to compare your answers.

Click the Wrk1 icon to open the command prompt for the workstation.
On Wrk1, use the following ping commands to verify that Wrk1 can communicate with all other workstations
through the switch:
○ ping 12.0.0.2
○ ping 12.0.0.3
○ ping 12.0.0.4
3. Click the Sales switch icon to open the switch console.
4. Press the Enter key.
5. Use the following commands to enter configuration mode for the switch:
○ enable
○ configure terminal
6. Type the vlan 12 command to create a new VLAN.
7. Type the following commands to assign the FastEthernet 0/1 interface to VLAN 12:
○ interface fastethernet0/1
○ switchport access vlan 12
8. Press Ctrl + Z to exit configuration mode on the switch.
9. Return to the Wrk1 window and ping each of the three other workstations. What happens? Why?
10. On the switch, use the following commands to modify the VLAN membership of the FastEthernet 0/3 port:
○ configure terminal
○ interface fastethernet0/3
○ switchport access vlan 12
11. Press Ctrl + Z to exit configuration mode on the switch.
12. From Wrk1, ping Wrk3. What happens? Why?
