Which two standard-base interface can the Cisco Unified Presence use to collect, aggregate, and distribute user capabilities and attributes?

REST is not a standard interface used by Cisco Unified Presence for aggregating and distributing user capabilities and presence attributes in this context.

HTTPS is a transport-layer security mechanism, not a standards-based application interface for collecting or distributing presence capabilities.

SOAP is a standards-based web-services protocol supported by Cisco Unified Presence to expose user capabilities and attributes via structured XML messaging to integrated applications and clients.

SIP is used by Cisco Unified Presence as a standards-based signaling protocol to collect and distribute presence state and user capability information across endpoints and federated domains.

XML is a data serialization format, not a protocol or interface - it is used within SOAP and SIP but is not itself a standalone interface for this purpose.
