Can VTP servers add, modify, or delete VLANs?

A VTP (VLAN Trunking Protocol) server is responsible for managing VLAN configurations across a network. Specifically, VTP servers can add, modify, and delete VLANs within their domain. This capability allows for centralized management of VLANs, making it easier to maintain consistency across switches that are part of the same VTP domain.

When a VLAN is added or modified on a VTP server, the change is propagated to all VTP clients within the same domain, effectively synchronizing VLAN information throughout the network. Similarly, if a VLAN is deleted, this removal is also communicated to the clients. This centralized approach simplifies VLAN management, reducing the potential for configuration inconsistencies between switches.

The correct answer reflects the full range of actions that a VTP server can perform, highlighting the flexibility and management efficiency that VTP provides in larger network environments where multiple VLANs are in use.
