A network engineer wants to perform a factory reset on a Cisco TelePresence MX device from the CLI. Which command should be used?

xConfiguration is the namespace for reading and setting configuration parameters, not for executing operational actions like a factory reset.

'xCommand FactoryReset' is an incomplete and invalid command because the SystemUnit subsystem must be specified to target the correct component for the reset operation.

The command 'xCommand SystemUnit FactoryReset' is the correct CLI syntax for resetting a Cisco TelePresence MX device to factory defaults, where 'xCommand' is the namespace for issuing executable actions and 'SystemUnit FactoryReset' specifies the target component and operation. This command resets all configuration values to their factory defaults and typically requires a confirmation parameter such as 'Confirm: Yes' to execute. It is part of the standardized Cisco TelePresence API used across endpoint product lines.

'xConfiguration SystemUnit FactoryReset' is invalid syntax because xConfiguration is used for configuration management and does not support action commands such as a factory reset.
