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).

Comprehensive Explanation: To remove the Eth-Trunk interface, you can simply use the undo interface Eth-Trunk 1 command. This command deletes the entire Eth-Trunk interface from the switch configuration. The other commands involve additional steps to unbind physical interfaces from the Eth-Trunk, but these steps are unnecessary if you are deleting the Eth-Trunk interface entirely.

Comprehensive Explanation: The user-interface maximum-vty command is used on Huawei devices to configure the maximum number of simultaneous VTY (Virtual Terminal Line) users who can log in via Telnet. By limiting the number of VTY sessions, the administrator can control how many users are able to access the device at the same time, preventing excessive connections that may overwhelm the device or reduce security.

Comprehensive Explanation: In Telnet sessions, different privilege levels determine what actions a user is allowed to perform. If users are not able to configure the IP address, it is likely that their privilege level is set incorrectly. The administrator must ensure that the Telnet users are assigned the correct privilege level (typically level 15 for full administrative rights) to allow configuration changes, including IP address modifications.
