Load the Rescue Configuration Command

B

The correct command to load the rescue configuration is C. "load replace rescue-configuration".

Here's a detailed explanation:

The rescue configuration is a safety net that can be used to restore a device's configuration to a known good state. It's typically created and saved separately from the main configuration and is used as a fallback in case the device's configuration becomes corrupted or otherwise unusable.

To load the rescue configuration, you need to replace the device's current configuration with the rescue configuration. You can do this using the "load replace" command, which replaces the entire configuration with a new one.

The syntax for the "load replace" command is as follows:

luaCopy code
load replace <filename> 

In this case, you need to specify the filename of the rescue configuration. By convention, Junos devices save rescue configurations with the filename "rescue.conf". So, the command to load the rescue configuration would be:

luaCopy code
load replace rescue-configuration 

Note that the filename is case-sensitive, so it must match exactly.

Option A ("load override rescue") is incorrect because the "load override" command loads a new configuration and overwrites the current one, but it doesn't replace the entire configuration. Option B ("rollback rescue") is also incorrect because the "rollback" command reverts the configuration to a previous commit, not to the rescue configuration. Finally, option D ("rollback 49") is incorrect because it rolls back the configuration to a specific commit, which may or may not be the rescue configuration.
