An engineer is configuring an endpoint to register to the Cisco VCS. To accomplish this goal, which two CLI commands are required? (Choose two.)

xCommand SIP Registrar Domain is not a valid TC software command - xCommand is reserved for one-time runtime actions and cannot set persistent registration configuration.

xConfiguration SIP Profile 1 Proxy 1 Address defines the IP address or hostname of the Cisco VCS, telling the endpoint where to send its SIP REGISTER requests.

xConfiguration SIP Profile 1 URI sets the endpoint's SIP address of record (e.g., user@domain), which is the identity the VCS uses to register and route inbound calls to the device.

xConfiguration Registrar 1 Profile does not exist in TC software CLI syntax - SIP registration parameters are configured under the SIP Profile hierarchy, not a standalone Registrar object.

xCommand SIP Registration Domain is not a valid TC software command - persistent SIP configuration requires xConfiguration, and this specific command path does not exist in the TC software command set.
