Which ports should be trunk ports on Server-1?

Trunk ports are used to carry traffic for multiple VLANs between switches and network devices. For Server-1, it's essential to identify which access ports can handle trunking.

The correct selection indicates that both Access-1 port 1/1/28 and Access-2 port 1/1/28 are configured as trunk ports. In many network designs, when servers are set up, they often connect to multiple VLANs for functionality; thus, configuring ports to support multiple VLANs is crucial for proper communication with different segments of the network.

Access-1 port 1/1/28 is likely set to operate in a mode that enables trunking, allowing it to pass traffic from more than one VLAN. Access-2 port 1/1/28 complements this by also functioning as a trunk port, facilitating seamless communication and ensuring that Server-1 can access various network resources across VLANs.

If the other choices were selected, they would indicate configurations that either limit the port's capability to a single VLAN or incorrectly pair ports within the same access layer without the necessary trunking to convey multiple VLAN traffic. Thus, both selected ports in the correct answer work together to ensure that Server-1 can operate effectively within a multi-VLAN
