A network manager wants to view network traffic for devices connected to a switch. A network engineer connects an appliance to a free port on the switch and needs to configure the switch port…

Trunking is used to carry traffic for multiple VLANs between switches or to a router, not for sending copies of traffic to a monitoring appliance.

Port mirroring (also known as SPAN on Cisco switches) is a feature that duplicates network traffic from one or more source ports or VLANs and sends it to a designated destination port. This allows a network analysis appliance connected to the destination port to non-intrusively monitor the traffic flowing through the switch.

Full duplex allows simultaneous two-way communication over a link, which is a basic operational mode for network interfaces, not a feature for monitoring traffic.

SNMP (Simple Network Management Protocol) is used for managing and monitoring network devices by collecting device statistics and configuration data, but it does not forward copies of actual network traffic for deep packet inspection.
