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

xConfiguration Registrar 1 Profile is not a valid CLI command in the Cisco endpoint xConfiguration namespace for SIP registration to VCS.

xConfiguration SIP Profile 1 Proxy 1 Address sets the IP address or FQDN of the VCS acting as the SIP proxy, which is mandatory to direct registration traffic to the correct server.

xCommand is used for transient one-time actions rather than persistent configuration; SIP registration parameters must be set with xConfiguration, not xCommand.

xConfiguration SIP Profile 1 Proxy Discovery defines how the endpoint locates its SIP proxy - setting this to 'Manual' in conjunction with the proxy address is required to complete a VCS-targeted SIP registration.

xCommand SIP Registrar Domain is not a valid persistent configuration command; endpoint registration settings require xConfiguration commands, not xCommand.
