Resolving "Rescue configuration is not set" Problem

A

The output of the "show system alarms" command displays a single active alarm that indicates a minor severity level and the description "Rescue configuration is not set." This alarm indicates that the router does not have a rescue configuration stored in memory.

To resolve this issue, we need to create and save a rescue configuration. The rescue configuration is a backup configuration that can be used to recover the router's system if the primary configuration becomes corrupted or unavailable. The correct command to use to save a rescue configuration is:

A. user@router> request system configuration rescue save

This command requests the router to create a rescue configuration and save it in the default location, /config/rescue.conf. The ">" symbol indicates that we are in operational mode, which is used to execute operational commands.

Option B is incorrect because "#" symbol indicates that we are in configuration mode, which is used to modify the router's configuration, not to execute operational commands.

Option C is incorrect because it copies the current active configuration to a file named "rescue.conf" in the root directory. This does not create a rescue configuration.

Option D is also incorrect because "#" symbol indicates that we are in configuration mode, which is not appropriate for copying files from one location to another.

Therefore, the correct answer is A. user@router> request system configuration rescue save.
