A network administrator needs to restore a saved configuration file named 'startup-config.bak' from a TFTP server at 10.0.0.1 to the running configuration of a Cisco switch. Which command sequence should the administrator use to perform this operation?
- Acopy running-config tftp://10.0.0.1/startup-config.bak
- Brestore tftp://10.0.0.1/startup-config.bak running-config
- Ccopy tftp://10.0.0.1/startup-config.bak running-config
- Dtftp get 10.0.0.1 startup-config.bak running-config
Show answer & explanationAnswer & explanation
Correct answer: C. copy tftp://10.0.0.1/startup-config.bak running-config
The 'copy' command is used to copy files between different locations on a Cisco device. The syntax 'copy <source> <destination>' is standard. In this case, the source is the TFTP server with the specific file, and the destination is the running configuration.
Why the other options are wrong
- A. This command attempts to copy the running-config TO the TFTP server, which is the opposite of the requirement.
- B. The 'restore' command is not a standard Cisco IOS command for this operation.
- D. The 'tftp get' command is not a standard Cisco IOS command for this operation; 'copy' is used instead.
Restore Config from TFTP
To restore a configuration file from a TFTP server to the running configuration on a Cisco device, use the 'copy tftp://<server-ip>/<filename> running-config' command.
- TFTP is a simple file transfer protocol.
- The 'copy' command has a consistent source-destination syntax.
- Running-config is the active configuration in RAM.
- Startup-config is the saved configuration in NVRAM.
Memory trick: Copy TFTP to Running, make it active!
