Which two configurations are needed for Cisco UCM location-based CAC? (Choose two.)

Automated Alternate Routing (AAR) CSS is a mechanism for rerouting calls when CAC fails, serving as a fallback, rather than being a direct configuration *for* CAC itself.

Cisco UCM's location-based CAC manages bandwidth for calls traversing WAN links between different locations, requiring the definition of audio bandwidth usage for calls and considering transcoder requirements to correctly calculate bandwidth consumption between these locations, ensuring sufficient bandwidth for audio calls.

Location-based CAC also needs to account for higher-bandwidth immersive video calls by defining the immersive video bandwidth requirements between different locations. Additionally, RSVP (Resource Reservation Protocol) integration can be enabled for these inter-location calls to provide explicit resource reservation, further ensuring call quality for video.

Video Resolution and DSCP settings are QoS markings and call quality attributes, but they are not the primary bandwidth *management* configurations for *inter-location* CAC, which focuses on bandwidth limits.

Audio and video bandwidth for calls *within the same location* is generally not constrained by location-based CAC, as CAC primarily addresses inter-location (WAN) bandwidth constraints, assuming sufficient LAN bandwidth.
