CompTIA Network+ (N10-008) — Question 211

During the troubleshooting of an E1 line, the point-to-point link on the core router was accidentally unplugged and left unconnected for several hours. However, the network management team was not notified. Which of the following could have been configured to allow early detection and possible resolution of the issue?

Answer options

Correct answer: A

Explanation

Traps are notifications sent from a network device to management systems when specific events occur, allowing for immediate awareness of issues like a disconnected link. MIBs and OIDs are used for managing and retrieving information from devices but do not provide real-time alerts. Baselines help in performance monitoring but do not directly notify about faults or disconnections.
