Cisco Telepresence System EX90 1 is trying to call Ex90 2. Both endpoints are registered to Cisco Unified Communications Manager. The Call connects but the quality is not good.
The video image is breaking up on EX 90 2. The media path from A to B supports only 2MB.
Which three reasons are possible causes? (Choose Three)
A. The Camera on System B has a loose cable.
B. The line is congested and QoS is not configured correctly between the sites.
C. Bandwidth limitations between the regions is set too low for video.
D. Bandwidth limitations between the IP zones is set too low for video.
E. The auto negotiation protocol H.286 is turned off on one of the EX90s.
F. The system is set to use a higher bandwidth than the media path allows.
In the other hand, if using the region default for video of 384k, that could cause bad video quality also.
If they ask for three answers I would choose BCF
Just B and F.
C would be rigth if it was like this
Bandwidth limitations between the regions is set too HIGH for video.
If that would be the case, it would negotiate a higher resolution and with a 2 Mbps link could cause quality issues.
