Question 21.  When a new trunk link is configured on an IOS-based switch, which VLANs are allowed over the link?

Question 22.  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?

Question 23.  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. Learning

Question 24.  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.

Question 29. . 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.

Question 30. . 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?
