Which two statements about the VLAN Trunking Protocol are true? (Choose two.)
Click on the arrows to vote for the correct answer
A. B. C. D. E.BC.
The VLAN Trunking Protocol (VTP) is a Layer 2 messaging protocol that is used to maintain VLAN consistency by managing the addition, deletion, and renaming of VLANs within a VTP domain. Here are the two true statements about VTP:
This statement is true. The VLAN Trunking Protocol is a Layer 2 messaging protocol that helps to maintain VLAN consistency in a VTP domain. It allows switches to advertise VLAN information to other switches within the same VTP domain. VTP messages are sent between switches to inform them about the VLANs that are available in the network, and to synchronize VLAN configuration information among the switches.
This statement is also true. VTP is supported on Layer 2 trunk interfaces, Layer 2 port channels, and virtual port channels. Layer 2 trunk interfaces are used to carry traffic for multiple VLANs over a single physical link. Layer 2 port channels allow you to bundle multiple physical links into a single logical link. Virtual port channels are used to bundle multiple physical links between two switches into a single logical link.
The other statements are false:
A. On Cisco Nexus switches, the VLAN Trunking Protocol is enabled by default.
This statement is false. By default, VTP is disabled on Cisco Nexus switches. You need to enable VTP manually if you want to use it.
D. The VLAN Trunking Protocol is a Layer 2 messaging protocol that maintains the interface VLAN configuring within the VLAN Trunking Protocol domain.
This statement is false. VTP does not maintain interface VLAN configuration. It only maintains VLAN configuration information.
E. The VLAN Trunking Protocol is only supported on Layer 2 trunk interfaces.
This statement is false. VTP is supported on Layer 2 trunk interfaces, Layer 2 port channels, and virtual port channels.
