Cisco Collaboration Exam - Configuration Changes to Improve Video Quality
Question
A jabber for window user is on a call with Cisco Telepresence EX90 endpoint at the same location.
During the call, the video on the jabber for Windows application was quality but the video on the EX90 was choppy and slow.
When the administration checked the service rate on the EX90, it showed 2048 KBps.
Which two configuration changes can fix this problem?

The problem mentioned in the question is related to video quality issues between a Cisco Jabber for Windows client and a Cisco TelePresence EX90 endpoint, where the video on Jabber for Windows is of good quality but the video on EX90 is choppy and slow, even though the service rate on EX90 is 2048 Kbps. To fix this problem, we need to make some configuration changes, as suggested in the answers:
A. Lower the bit rate in the region configuration in communication manager between the endpoints. This option suggests lowering the bit rate in the region configuration between the endpoints, which can help to reduce the amount of bandwidth required for the call. However, it may also result in a lower video quality, which may not be desirable.
B. Increase the location bandwidth for immersive video between the endpoints. This option suggests increasing the location bandwidth for immersive video between the endpoints, which can help to provide more bandwidth for the call, resulting in better video quality. However, it may not always be feasible to increase the bandwidth, especially in situations where bandwidth is limited.
C. Enable BFCP in the SIP profile for the jabber client. This option suggests enabling BFCP (Binary Floor Control Protocol) in the SIP profile for the Jabber client, which can help to improve the video quality by allowing the client to control the video flow between endpoints. BFCP can help to reduce video latency and improve video quality, especially in situations where bandwidth is limited.
D. Enable H.263 on the EX90. This option suggests enabling H.263 video codec on the EX90 endpoint. H.263 is an older video codec that is more efficient in terms of bandwidth usage compared to newer codecs like H.264. However, enabling H.263 may result in a lower video quality compared to H.264.
E. Replace the camera for the jabber user with the precision HD USB camera. This option suggests replacing the camera for the Jabber user with a precision HD USB camera. This can help to improve the video quality on the Jabber client. However, it may not necessarily improve the video quality on the EX90 endpoint.
F. Increase the bandwidth between the jabber video client and the EX90. This option suggests increasing the bandwidth between the Jabber video client and the EX90 endpoint, which can help to provide more bandwidth for the call, resulting in better video quality. However, it may not always be feasible to increase the bandwidth, especially in situations where bandwidth is limited.
In summary, the best options to fix the video quality issue between Jabber for Windows and EX90 would be to enable BFCP in the SIP profile for the Jabber client (option C) and/or increase the location bandwidth for immersive video between the endpoints (option B). These options can help to improve the video quality without necessarily compromising on bandwidth usage or video codec quality.
