Question 1 of 17
1. Question
Which of the following is true regarding VLANs?
Correct
Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunk Protocol (VTP) is used to propagate VLAN information across a trunked link.

Question 2 of 17
2. Question
Which protocol reduces administrative overhead in a switched network by allowing the configuration of a new VLAN to be distributed to all the switches in a domain?
Correct
Virtual Trunk Protocol (VTP) is used to pass a VLAN database to any or all switches in the switched network. The three VTP modes are server, client, and transparent.

Question 3 of 17
3. Question
Which of the following is true regarding VTP?
Correct
All Cisco switches are VTP servers by default. No other VTP information is configured on a Cisco switch by default. You must set the VTP domain name on all switches to be the same domain name or they will not share the VTP database.
Incorrect
All Cisco switches are VTP servers by default. No other VTP information is configured on a Cisco switch by default. You must set the VTP domain name on all switches to be the same domain name or they will not share the VTP database.

Question 4 of 17
4. Question
Which of the following commands sets a trunk port on a 2960 switch?
Correct
To set a switch port to trunk mode, which allows all VLAN information to pass down the link, use the switchport mode trunk command.
Incorrect
To set a switch port to trunk mode, which allows all VLAN information to pass down the link, use the switchport mode trunk command.

Question 5 of 17
5. Question
Which command will configure a switch port to use the IEEE standard method of inserting VLAN membership information into Ethernet frames?
Correct
If you are on a 2950 switch, then the interface command is just switchport mode trunk, since the 2950 can only run the IEEE 802.1Q version. However, a 3550 can run both ISL and 802.1Q, so you must use the encapsulation command. The argument to choose 802.1Q for a trunking protocol is dot1q.

Question 6 of 17
6. Question
When a new trunk link is configured on an IOS-based switch, which VLANs are allowed over the link?
Correct
By default, all VLANs are allowed on the trunk link and you must remove by hand each VLAN that you don’t want traversing the trunked link.
Incorrect
By default, all VLANs are allowed on the trunk link and you must remove by hand each VLAN that you don’t want traversing the trunked link.

Which of the following modes are valid when a switch port is used as a VLAN trunk?
1. Blocking
2. Dynamic auto
3. Dynamic desirable
4. Nonegotiate
5. Access
6. LearningCorrect
The valid modes of a VLAN trunk on a switch are dynamic auto, dynamic desirable, trunk (on), and nonegotiate.
Incorrect
The valid modes of a VLAN trunk on a switch are dynamic auto, dynamic desirable, trunk (on), and nonegotiate.

Question 8 of 17
8. Question
To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met?
- Each end of the trunk link must be set to the IEEE 802.1e encapsulation.
- The VTP management domain name of both switches must be set the same.
- All ports on both the switches must be set as access ports.
- One of the two switches must be configured as a VTP server.
- A rollover cable is required to connect the two switches together.
- A router must be used to forward VTP traffic between VLANs.
Correct
You must have the same VTP domain name on all switches in order to share VLAN information between the switches. At least one of the switches must be a VTP server; the other switches should be set to VTP client.
Incorrect
You must have the same VTP domain name on all switches in order to share VLAN information between the switches. At least one of the switches must be a VTP server; the other switches should be set to VTP client.

Question 9 of 17
9. Question
You want to improve network performance by increasing the bandwidth available to hosts and limit the size of the broadcast domains. Which of the following options will achieve this goal?
Correct
By creating and implementing VLANs in your switched network, you can break up broadcast domains at layer 2. For hosts on different VLANs to communicate, you must have a router or layer 3 switch.

Correct
Virtual LANs break up broadcast domains in layer 2 switched internetworks.
Incorrect
Virtual LANs break up broadcast domains in layer 2 switched internetworks.

Question 11 of 17
11. Question
Which of the following provide inter-switch VLAN communication?
- ISL
- VTP
- 802.1Q
- 802.3Z
Correct
ISL is a Cisco-proprietary frame-tagging method. IEEE 802.1Q is the nonproprietary version of frame tagging.
Incorrect
ISL is a Cisco-proprietary frame-tagging method. IEEE 802.1Q is the nonproprietary version of frame tagging.

Question 12 of 17
12. Question
A switch has been configured for three different VLANs: VLAN2, VLAN3, and VLAN4. A router has been added to provide communication between the VLANs. What type of interface is necessary on the router if only one connection is to be made between the router and the switch?
Correct
Although you can use either 100Mbps or 1Gbps Ethernet, the 100Mbps is necessary at a minimum and is the best answer to this question. You need to trunk the link from the switch to the router to make this connection work with inter-VLAN communication.
Incorrect
Although you can use either 100Mbps or 1Gbps Ethernet, the 100Mbps is necessary at a minimum and is the best answer to this question. You need to trunk the link from the switch to the router to make this connection work with inter-VLAN communication.

Question 13 of 17
13. Question
Which of the following are benefits of VLANs?
- They increase the size of collision domains.
- They allow logical grouping of users by function.
- They can enhance network security.
- They increase the size of broadcast domains while decreasing the number of collision domains.
- They simplify switch administration.
- They increase the number of broadcast domains while decreasing the size of the broadcast domains.
Correct
VLANs break up broadcast domains in a switched layer 2 network, which means smaller broadcast domains. They allow configuration by logical function instead of physical location and can create some security if configured correctly.

Question 16 of 17
16. Question
You connect a host to a switch port, but the new host cannot log into the server that is plugged into the same switch. What could the problem be?
Correct
This question is a little vague, but the best answer is that the VLAN membership for the port is not configured.
Incorrect
This question is a little vague, but the best answer is that the VLAN membership for the port is not configured.
