VTP is a Layer 2 messaging protocol that maintains VLAN configuration consistency by managing the addition, deletion, and renaming of VLANs within a VTP domain.
Correct
VLAN Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. VTP protocol has 3 modes: Server, Client & Transparent. There is only 1 server and all other switches in that environment are Clients. The only server can create, modify and delete VLAN so in a VTP environment VLANs are consistent across the network. The changes made on the Server are automatically propagated to all the clients through the TRUNK links established between the switches.
