The correct answer is C. Port mirroring. Port mirroring (also called SPAN - Switched Port Analyzer) configures a switch to copy all traffic from one or more source ports to a designated destination port connected to a monitoring device (e.g., a packet analyzer or IDS sensor). This allows passive inspection of all…

Explanation

Port mirroring (also called SPAN - Switched Port Analyzer) configures a switch to copy all traffic from one or more source ports to a designated destination port connected to a monitoring device (e.g., a packet analyzer or IDS sensor). This allows passive inspection of all traffic without disrupting normal network flow. Traffic shaping controls bandwidth usage, MAC filtering restricts access by hardware address, and VLAN trunking carries multiple VLANs over a single link - none of these enable passive packet monitoring.
