Which command would you use to copy a configuration file from a network server to a Cisco device?

The command "copy tftp run" is used to copy a configuration file from a TFTP (Trivial File Transfer Protocol) server to the running configuration of a Cisco device. This command is a standard in Cisco IOS (Internetwork Operating System) for transferring files and is specifically designed to facilitate the movement of configurations to and from network devices.

When using this command, you will typically be prompted to enter the TFTP server's IP address and the filename you wish to copy. The "run" portion of the command indicates that the configuration will be applied directly to the device's running configuration, which means any active settings will be updated immediately.

This command is particularly useful during operations such as backup, restoration, and modifications of device configurations. Its simplicity and directness make it a preferred choice among network engineers for managing configurations efficiently.
