In a VTP configuration, what does the VTP domain name define?

The VTP domain name is crucial in the context of a VLAN Trunking Protocol (VTP) configuration, as it plays a significant role in maintaining the integrity of the VLAN database across a network. When switches are assigned to the same VTP domain, they can share information about VLANs dynamically. This means that if a VLAN is added, deleted, or modified on one switch, that change is propagated to all other switches within the same VTP domain. This coordination is essential for ensuring that the VLAN configurations remain consistent and synchronized, preventing VLAN-related errors and mismatched configurations across the network.

By controlling the VLAN database integrity in this way, the VTP domain name helps to manage and maintain the logical topology of the network efficiently, allowing for better scalability and easier management of VLANs.
