Exercise :: Virtual LANs - Virtual LANs
- Virtual LANs - Virtual LANs
1. | Which of the following is true regarding VLANs? |
|||||||
Answer: Option D Explanation: 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.
|
2. | 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? |
|||||||
Answer: Option B Explanation: 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.
|
3. | Which of the following is true regarding VTP? |
|||||||
Answer: Option A Explanation: 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.

4. | Which of the following commands sets a trunk port on a 2960 switch? |
|||||||
Answer: Option D Explanation: To set a switch port to trunk mode, which allows all VLAN information to pass down the link, use the switchport mode trunk command.
|
5. | Which command will configure a switch port to use the IEEE standard method of inserting VLAN membership information into Ethernet frames? |
|||||||||
Answer: Option E Explanation: 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.
