The correct answer is C. Rendezvous.
In Cisco IOS, a multipoint video conference is established using a video conferencing profile. The video conferencing profile specifies the configuration parameters for the conference, including the type of conference, audio and video codecs to be used, and other characteristics.
The Rendezvous profile attempts to reserve DSPs only when it is activated with an actual conference. This means that the DSP resources are not reserved until the conference is established, which allows for more efficient use of DSP resources in the system.
On the other hand, the other video conferencing profiles mentioned in the question are:
A. Homogeneous: This profile uses only one codec for audio and video. This profile is useful when all endpoints in the conference have similar capabilities and use the same codec.
B. Guaranteed-audio: This profile reserves DSP resources for audio even if no audio is present in the conference. This ensures that audio quality is not compromised in the conference.
D. Heterogeneous: This profile allows the use of different audio and video codecs for different endpoints in the conference. This profile is useful when endpoints have different capabilities and use different codecs.
E. Flex mode video: This profile allows endpoints to negotiate different video resolutions and frame rates based on their capabilities. This allows for more efficient use of network bandwidth and system resources.
In summary, the Rendezvous video conferencing profile attempts to reserve DSPs only when it is activated with an actual conference, which allows for more efficient use of DSP resources in the system.
