The correct answer is D. Configure VTP (VLAN Trunking Protocol).

VLANs (Virtual Local Area Networks) are used to segment networks logically and help to reduce broadcast traffic. VLANs can be created and assigned manually on each switch, which can be a time-consuming and error-prone process, especially when dealing with large networks. VTP is a Cisco proprietary protocol that allows for the automatic distribution of VLAN configuration information across multiple switches in a network.

When VTP is enabled on a switch, it can act as a VTP server, client, or transparent device. The VTP server is responsible for managing the VLAN configuration information and distributing it to other switches in the same VTP domain. The VTP client receives the VLAN configuration information from the VTP server and applies it to its own configuration. The VTP transparent device forwards VTP packets but does not participate in VLAN configuration management.

When a new VLAN is created on a VTP server, it is automatically propagated to all other switches in the same VTP domain. This ensures that all switches have the same VLAN configuration and reduces the likelihood of VLAN configuration errors.

Therefore, if you want to distribute VLANs automatically across multiple switches, you need to configure VTP. It is important to note that VTP should be used with caution and configured properly to avoid unintended consequences such as overwriting existing VLAN configurations or propagating incorrect VLAN information.
