A. B. C. D.C.
Option B is the correct command set to recover the backup configuration file from a Cisco Nexus 9000 Series Switch that has experienced a startup configuration corruption. Here's a detailed explanation of each step in this command set:
Clear the current configuration of the switch: This step is necessary to remove any corrupt or invalid configurations that may be causing issues with the switch's startup process. The command to clear the configuration is "write erase".
Restart the device: After clearing the configuration, the switch needs to be restarted to initiate the recovery process. The command to restart the device is "reload".
Copy the running configuration to the startup configuration: Once the switch has restarted, the running configuration needs to be copied to the startup configuration to ensure that the switch boots up with a valid configuration. The command to copy the running configuration to the startup configuration is "copy running-config startup-config".
Copy a previously saved configuration file to the running configuration: Finally, the backup configuration file needs to be restored by copying it to the running configuration. The command to copy a previously saved configuration file to the running configuration is "copy tftp running-config". This command will prompt the engineer to specify the IP address of the TFTP server and the name of the backup configuration file.
Option A is incorrect because it restores the old configuration file before copying the running configuration to the startup configuration, which could potentially result in the restored configuration file causing further issues.
Option C is incorrect because it copies the running configuration to the startup configuration before clearing the current configuration, which could result in the switch booting up with a corrupt or invalid configuration.
Option D is incorrect because it does not involve copying the backup configuration file to the running configuration, which means the switch would not be using the latest valid configuration file after the recovery process.
