| Question ID 13056 | Which Cisco IOS multipoint video conferencing profile is also known as best-effort video on
the Cisco Integrated Router Generation 2 with packet voice and video digital signal
processor 3?
|
| Option A | homogeneous
|
| Option B | guaranteed-audio
|
| Option C | rendezvous
|
| Option D | heterogeneous
|
| Option E | flex mode video
|
| Correct Answer | B |
Explanation Explanation: Three types of video profiles are supported: homogeneous conferences (video switching), heterogeneous conferences (video mixing), and guaranteed audio conferences (best-effort video). As the name suggests, when Guaranteed Audio Conferences is configured, the system attempts to display video for all participants; however, it does not guarantee that the video of all participants is displayed. For those participants whose video is not displayed, participants are downgraded to audio-only and the profile guarantees preservation of the audio portion of the call. This option gives you added flexibility because the DSPs are not all reserved when the profile is created; the system attempts to reserve them when this profile is activated with an actual conference. For example: dspfarm profile 1 conference video guaranteed-audio codec h264 vga codec h264 4cif Reference: http://www.cisco.com/c/en/us/products/collateral/unified-communications/voice-video- conferencing-isr-routers/qa_c67-649850.html

Explanation Explanation: The integrated video conferencing services use the same DSP resources on PVDM3s that are used for widely deployed ISR G2 voice capabilities. These modules, in conjunction with Cisco IOS Software, perform audio and video mixing, video transcoding for certain resolutions, and other functions for video endpoints. PVDM3 modules support flexible media resources and conference profile management to maximize capacity with predictable end-user experiences. Both homogenous and heterogonous video conferences are supported. A homogenous conference refers to one in which participants connect to the ISR G2 with devices that support the same video format attributes (for example, the same codec, resolution, frame rate, and bit rate). A heterogeneous conference refers to one in which participants can connect to a conference bridge with devices that support different video format attributes. Each conference allows 4-, 8-, or 16-party participants.
