In a VTP server mode, what can the switch do?

In VTP (VLAN Trunking Protocol) server mode, a switch has the capability to both update and propagate VLAN information throughout the network. This functionality is crucial for managing VLAN configurations across multiple switches in a network.

When a switch operates in server mode, it can create, modify, and delete VLANs. Once changes are made, the server switch advertises these changes to all other switches in the same VTP domain. This ensures that all switches maintain a consistent view of the VLAN structure, leading to better network management and fewer configuration errors.

The ability to propagate VLAN information allows network administrators to manage VLANs from a central point (the VTP server) rather than configuring each switch individually. This results in a more efficient and streamlined approach to VLAN management across the network.

In contrast, other options such as only receiving VLAN configuration or just reporting VLAN status don't reflect the full capabilities of a VTP server. Additionally, the ability to delete VLANs is not a standalone function of VTP server mode but rather a part of the broader capability to manage VLANs effectively.
