The Cisco TMS administrator is trying to add participants while booking a new conference. Which three options are presented? (Choose three.)

Endpoints are video and telepresence systems registered in Cisco TMS and represent the physical or software-based devices that join conferences. They are the primary participant type available in the TMS conference booking workflow.

Users are TMS accounts associated with one or more devices, and adding a user allows TMS to route the call to whichever of their devices is available. This is a distinct participant selection option separate from selecting individual endpoints.

Cisco MCUs are multipoint bridging infrastructure devices managed within TMS and can be added as conference participants to provide bridging capacity. Selecting an MCU as a participant reserves its resources for the scheduled conference.

Multiway address is a mechanism for ad-hoc escalation of point-to-point calls to multipoint conferences and is not a participant category presented in the TMS booking interface.

Directory numbers synced from CUCM are telephony identifiers for IP phone routing and are not presented as a selectable participant type during TMS conference booking.

SIP URIs synced from CUCM represent unified communications endpoints but are not offered as a distinct participant selection option in the TMS conference booking workflow.

Video AutoAttendant numbers are IVR routing constructs that allow callers to join conferences via DTMF tones and are not a participant type selectable during TMS booking.
