Network devices running SNMP can proactively report traps to help network administrators detect faults in a timely manner.

The statement is correct. A primary feature of the Simple Network Management Protocol (SNMP) is the ability of a managed device (an agent) to send unsolicited messages, called traps, to a Network Management Station (NMS). This mechanism allows the device to proactively report significant events, such as faults, configuration changes, or threshold breaches, without waiting to be polled by the NMS. This enables network administrators to receive timely notifications and respond to issues quickly.

This is a true/false question where the statement itself is the subject of evaluation. The statement accurately describes the function of SNMP traps, so there are no incorrect options to analyze in the traditional sense. The statement is factually correct.
