What is the purpose of the SNMP trap message?
- It traps an agent into performing a device reboot.
- It performs a write to a MIB variable on the agent.
- It transmits an unsolicited condition from agent to manager.
- Trap is not an SNMP message.
Explanation: The purpose of an SNMP trap is to provide a mechanism for a managed device (the SNMP agent) to send unsolicited notifications to the network management system (the SNMP manager).
Unlike standard SNMP polling, where the manager periodically queries the agent for data, traps are event-based. They provide almost real-time notifications when specific conditions occur, such as a change in device status or when a pre-configured performance threshold has been reached. This allows administrators to be alerted to irregular events, such as device unavailability or increased traffic, without waiting for the next scheduled poll.
