What is the main advantage of using traps in SNMP?

The main advantage of using traps in SNMP (Simple Network Management Protocol) is to maintain simplicity and minimize traffic. Traps are asynchronous notifications sent from an SNMP agent to an SNMP manager when certain events or thresholds are met. Unlike polling, where the SNMP manager regularly requests data from the devices, traps eliminate the need for continuous interrogation of devices. This reduces network traffic significantly, as the manager receives updates only when there are pertinent changes or issues that need attention.

This approach allows for more efficient use of bandwidth and reduces the load on both the managed devices and the management system. Traps are particularly beneficial in environments where resource conservation is essential, enabling prompt responses to important events without the overhead of constant polling.

Other choices, while they may suggest potential aspects of SNMP operation, do not capture the essence of the primary benefit of traps. For example, complex data manipulation and increased communication speed do not align with the fundamental purpose of traps in simplifying management and reducing unnecessary data traffic. Continuous polling, while effective in keeping tabs on device statuses, introduces higher traffic levels and is less efficient than the trap mechanism.
