What is an available command on an Aruba AOS-CX switch that would back up the secondary image to a remote repository?

The command that effectively backs up the secondary image to a remote repository for an Aruba AOS-CX switch is the one that uses the correct syntax and parameters for the intended operation. In this case, the command follows the proper structure for copying the secondary operating system image to a TFTP server.

Using the "copy" command with the appropriate syntax allows the switch to transfer the file from its storage to the specified remote repository, which is necessary for backups and ensures that if the primary image fails, there is a secondary option available to boot from. The format of the command indicates that it is defining a source (the secondary image) and a destination (the TFTP server), which is essential for a successful backup operation.

The inclusion of the TFTP protocol in this command is significant, as it is a common method used for transferring files in network environments. The command format encompasses the remote address and file name, ensuring that the switch can identify where to send the backup and what to name it upon arrival at the destination.

This command is the correct choice because it abides by the proper command syntax, uses the appropriate protocol for file transfer (TFTP), and is specifically designed for backing up the secondary image from the switch to a remote repository.
