Huawei network devices provide several information-management mechanisms, including logs, traps, debugging information, and SNMP management data.
Log information is the appropriate starting point when investigating a configuration change made by an administrator.
Depending on the device software version and enabled logging functions, configuration-operation logs may record commands executed by administrators, including IP address modifications and deletions.
The administrator can examine available logs using commands such as display logbuffer or investigate saved log files.
SNMP agent information primarily provides information used by management systems. Trap messages normally report significant events or state changes, while debugging information provides detailed protocol or system diagnostics.
Neither traps nor debugging output is the primary source for reconstructing an accidental configuration change.
Therefore, option C is correct. Recovering the exact deleted address depends on whether the relevant configuration-operation records were retained.
