Q.
What video conferences are supported? A.
Three types of video profiles are supported: homogeneous conferences (video switching), heterogeneous conferences (video mixing), and guaranteed audio conferences (best-effort video)

The Cisco IOS multipoint video conferencing feature allows for three or more endpoints to participate in a video conference. The Cisco Integrated Router Generation 2 with packet voice and video digital signal processor 3 supports two Cisco IOS multipoint video conferencing profiles: rendezvous and ad-hoc.
A rendezvous conference is a predefined conference that requires all endpoints to join at a specific time and location. In a rendezvous conference, the router acts as the central controller and the conference is initiated by the router. Endpoints join the conference by dialing into the router's conference bridge. The router assigns a conference ID to the conference and provides it to all endpoints. The rendezvous profile is useful for scheduled, planned meetings that require advanced planning.
An ad-hoc conference, on the other hand, is an impromptu conference that can be initiated by any endpoint without advanced planning. In an ad-hoc conference, any endpoint can initiate the conference by dialing into the router's conference bridge. The router assigns a conference ID to the conference and provides it to all endpoints. The ad-hoc profile is useful for meetings that require immediate collaboration without advanced planning.
The other profiles listed in the answer choices are not supported on the Cisco Integrated Router Generation 2 with packet voice and video digital signal processor 3.
Guaranteed-audio and guaranteed-video are Quality of Service (QoS) profiles that prioritize audio and video traffic over other types of traffic to ensure quality transmission. These profiles are not related to multipoint video conferencing.
Homogeneous and scheduled profiles are not supported on the Cisco Integrated Router Generation 2 with packet voice and video digital signal processor 3. The homogeneous profile is used when all endpoints have the same capabilities, and the scheduled profile is used when the conference is scheduled in advance with a start and end time.
In summary, the two Cisco IOS multipoint video conferencing profiles supported on the Cisco Integrated Router Generation 2 with packet voice and video digital signal processor 3 are rendezvous and ad-hoc.
