What is the role of the VTP server mode?

The role of the VTP server mode is to manage and propagate VLAN configuration information within a VTP domain. In this mode, switches can create, modify, and delete VLANs, and these changes are communicated to all other switches in the same VTP domain. This centralized management of VLANs helps ensure that all switches maintain consistent VLAN data, simplifying network administration.

By propagating VLAN changes across the network, the VTP server mode not only facilitates better organization of VLANs but also reduces the chances of configuration errors and inconsistencies that can occur when managing VLANs individually on each switch. In contrast, other options describe functionalities that do not capture the comprehensive capabilities of the VTP server mode or highlight the limited roles of other modes like client or transparent, which do not have the ability to manage VLANs or communicate changes effectively as the server mode does.
