Which term describes the action of enabling a switch to send a copy of all traffic to a monitoring device by configuring a mirror port?

• A. SPAN or Mirrored Port
• B. Traffic Mirroring
• C. Remote Traffic Mirroring
• D. Local Traffic Mirroring

Answer: (A)

Port mirroring is the action of configuring a switch to send a copy of traffic to a monitoring device. By designating a destination port—the mirror port—the switch duplicates frames from one or more source ports and forwards those copies to the monitoring device for analysis. This lets you observe what’s happening on the network without interrupting or altering the original traffic flow. The standard term for this on many switches is SPAN, which stands for Switch Port Analyzer, and it’s commonly referred to as a mirrored port. Using SPAN keeps the monitoring process local to the switch; if you needed to monitor traffic across multiple switches, you’d look into remote options (RSPAN or ERSPAN), but the described action aligns with SPAN or a mirrored port.
