Which of the following is true regarding VTP?
Answer: A
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.

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?
Answer: C
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.

To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met?
1.Each end of the trunk link must be set to the IEEE 802.1e encapsulation.
2.The VTP management domain name of both switches must be set the same.
3.All ports on both the switches must be set as access ports.
4.One of the two switches must be configured as a VTP server.
5.A rollover cable is required to connect the two switches together.
6.A router must be used to forward VTP traffic between VLANs.
Answer: C
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.

Which of the following are benefits of VLANs?
1.They increase the size of collision domains.
2.They allow logical grouping of users by function.
3.They can enhance network security.
4.They increase the size of broadcast domains while decreasing the number of collision domains.
5.They simplify switch administration.
6.They increase the number of broadcast domains while decreasing the size of the broadcast domains.
Answer: D
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.

When a new trunk link is configured on an IOS-based switch, which VLANs are allowed over the link?
