Which two technologies comprise a Cisco Presence deployment? (Choose two.)

Cisco Unified Presence Server (CUPS) is the dedicated component that aggregates and distributes presence information and enables instant messaging within the Cisco collaboration architecture.

Cisco Unity Connection is a voicemail and unified messaging platform, not a presence component.

Cisco Unified Communications Manager is required because CUPS integrates directly with CUCM to retrieve user and device information and to reflect telephony presence states such as on-hook or off-hook.

Active Directory is a directory service that may be used for user provisioning but is not a core Cisco Presence technology.

Cisco Unified Border Element is a SIP session border controller used for interconnecting VoIP networks, not related to presence services.

Cisco Expressway provides mobile and remote access for endpoints but is not a core component of a Presence deployment.
