Traps are the best choice because they allow network devices to send unsolicited alerts (or traps) to the network management system (NMS) when specific events occur, such as unexpected shutdowns or high resource usage. While the Management information base (MIB) provides the structure for network data and what can be monitored, it does not by itself enable or trigger alerts. Community strings function as passwords to authenticate access to a device's data and do not deal with alerts. Authentication techniques ensure secure communication in the network but are not directly responsible for triggering event-based notifications.
