A. B. C. D.C
VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol that enables the management of VLANs across multiple switches. VTP modes are used to specify how switches exchange VLAN information and how they handle incoming and outgoing VLAN traffic.
There are three different VTP modes:
Server Mode: In this mode, switches can create, modify, and delete VLANs. The changes made on the server mode switch are propagated to all other switches in the same VTP domain.
Client Mode: In this mode, switches can receive and forward VTP information, but they cannot create, modify, or delete VLANs. Client mode switches depend on VTP advertisements from server mode switches to update their VLAN information.
Transparent Mode: In this mode, switches can create, modify, and delete VLANs, but they do not participate in VTP advertisement distribution. Transparent mode switches do not store VLAN information in their configuration file and do not forward VTP advertisements.
Answer D, "Transparent mode," is the VTP mode that prevents changes to VLANs. In this mode, switches can create, modify, and delete VLANs, but they do not participate in VTP advertisement distribution. Transparent mode switches do not store VLAN information in their configuration file and do not forward VTP advertisements. Therefore, any changes made to VLANs on a transparent mode switch will not be propagated to other switches in the VTP domain.
