CompTIA Network+ (N10-009) — Question 136

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 connected to the appliance. Which of the following is the best option for the engineer to enable?

Answer options

• A. Trunking
• B. Port mirroring
• C. Full duplex
• D. SNMP

Correct answer: B

Explanation

Port mirroring allows the switch to send a copy of the network traffic from one port to another, enabling the engineer to monitor the traffic effectively. Trunking is used for carrying multiple VLANs, which is not the goal here. Full duplex refers to simultaneous two-way communication, and SNMP is a protocol for network management, neither of which directly allows traffic monitoring.
