The Network Management Station uses SNMP to manage devices. Which SNMP message is sent when an SNMP-registered abnormal event occurs?
trap
get-request
set-request
get-response
SNMP Message Types:
get-request: Sent by the NMS to retrieve data from a device.
set-request: Used by the NMS to modify device settings.
get-response: Sent by the device in response to a get-request.
trap: Sent automatically by a device to notify the NMS of an event.
Why "trap" Is Correct:
If a registered event occurs (e.g., interface down, high CPU usage), the device proactively sends a trap to alert the NMS.
Conclusion:
Since traps notify abnormal events, the correct answer is A (trap).
