Exam 350-801 topic 1 question 73 discussion

This is one of those "trick" questions that really does not have a clear answer and is more in "reading between the lines," in typical Cisco exam fashion. Answer A: This cannot be right because that would be an assumption. 8945s have built-in video/camera. Answer B: The codecs in the list and max bitrate show no issue, so this is not it. Answer C: This is the best choice based on the information provided. The section in the question of "when the 9971 CONFERENCES IN the 8945..." indicating that the 8945 is being added to an already in-progress video call, totaling three or more video streams. This would mean 384kbps is definitely way too low. Answer D: This is wrong because neither of these devices are immersive (not SX, DX, MX, IX, etc., aka Telepresence).

I believe the answer should be A, even with the 384 kbps bandwidth, the video calls and conferences are allowed and they do work, with lower resolution. Answer C could be right when the question is about 'low video quality'

It is very "tricky" this question, it is my point of view: A. could be just an assumption (as Slushed told us, because CP8945 has built-in camera. B. The audio bit rate nothing to do here. C. As Slushed told us, there are three video stream, however, there is not information about the locations configuration, just regions. Also SIF (352x240) @ 30fps and QCIF (176x144) @ 30fps are also below of 384 kbps. D. it is not inmersive video. So I think, in order of the presented information, it could fall in the assumption that the Phone has not a connected camera, the closest answer could be A.

I think C is correct not A, that because Cisco 8945 has a built-in Camera so, how the camera is not connected, maybe the shutter is closed but this is not an answer in the choices so, C is the best choise in this situation.

Does a 9971 even have a video bridge built in? It's not stated anywhere they have a complete CMS solution running. Perhaps it's to be expected that the conference becomes audio-only.

Another tricky question. I go with answer B, and the audio should be connected and then the video. Low bandwidth on audio REGION1 is 60kbps, and can’t make audio to REGION2 which is 64kbps, no bandwidth the call disconnected.
