正解:C
Option C is the correct command to make an XML backup of Cisco UCS Manager. The command creates a backup file named "all-config9.bak" that contains all system and service profiles configuration. The command also specifies the protocol as SCP (Secure Copy Protocol), which transfers the backup file using an authenticated and encrypted tunnel. References:
