A. B. C. D. E.AE.
VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol that manages VLAN configurations across a switched network. Here are the two correct statements about VTP:
A. All switches must be configured with the same VTP domain name: This statement is true. A VTP domain is a group of switches that share the same VLAN information. All switches in the same VTP domain must have the same domain name configured. This ensures that they can communicate with each other and synchronize VLAN information.
C. All switches must be configured with a unique VTP domain name: This statement is also true. Although it may seem contradictory to the previous statement, it is important to note that each VTP domain name must be unique across the entire network. This means that if you have multiple VTP domains, each domain must have a different name. However, all switches within a particular VTP domain must have the same VTP domain name.
B, D, and E are false statements:
B. All switches must be configured to perform trunk negotiation: This statement is false. While it is true that VTP requires VLAN information to be carried over trunk links, not all switches in the network need to be configured to perform trunk negotiation. In fact, access ports (ports that carry traffic for only one VLAN) can be configured on switches that are not participating in VTP at all.
D. The VTP server must have the highest revision number in the domain: This statement is false. While the VTP server does maintain a revision number to track changes to the VLAN database, there is no requirement that the VTP server must have the highest revision number. In fact, if a VTP client switch has a higher revision number than the server, the client's VLAN database will be used to update the server.
E. All switches must use the same VTP version: This statement is false. While it is generally a good practice to ensure that all switches in the network are using the same VTP version, it is not strictly required. In fact, some older switches may not support newer versions of VTP and may need to be configured to use an older version. However, it is generally recommended to use the latest version of VTP available to ensure the best functionality and security.
