Which command would you use to verify the configuration was correctly copied to the TFTP server?

The command that is used to verify that the configuration has been correctly copied to the TFTP server is intended to check the currently running configuration of the device rather than directly inspecting the TFTP server contents. However, in practice, when you issue a command to copy configurations to the TFTP server, you typically follow up by using the appropriate commands to ensure successful completion of that process.

The correct option is actually not listed among the choices provided. A more accurate method to verify the configuration on the TFTP server would involve checking through the TFTP server itself or using specific tools or commands designed for that purpose, such as accessing the TFTP server management interface or employing commands like "show file" if supported, to view the files stored.

The command "show running-config" reveals the current configuration that is active on the device, but it does not verify the state of the configuration on the TFTP server. In this case, the given answer would not fulfill the requirement to verify the TFTP upload directly based on accepted practices regarding TFTP server verification processes in most network configurations.
