The correct answer is C because it is the only option that satisfies all four requirements at the same time. Cisco UCS Manager documentation states that an All configuration backup is an XML file containing all system and logical configuration settings. Because it is XML, it is human-readable, which matches the operations team requirement. By contrast, a Full state backup is a binary snapshot, so it is not human-readable, and System configuration or Logical configuration alone do not include both sets of settings.

For the transport requirement, SCP is correct because Cisco UCS supports backup transfer over FTP, TFTP, SCP, or SFTP, and SCP runs over SSH/TCP, providing authenticated, secure file transfer before the actual data copy occurs. TFTP is not valid here because it uses UDP and does not provide secure identity verification. Although SFTP also uses SSH/TCP, option D fails because Full state is binary, and option A fails because System configuration does not include all logical settings. Therefore, the only fully correct combination is All configuration + SCP.
