A. B. C. D. E. F.CF.
The VideoStream functionality on the Wireless LAN Controller (WLC) allows for the efficient and reliable delivery of multicast video streams over wireless networks. Here are the correct statements regarding VideoStream functionality:
C. It applies only to the configured media streams. This statement is true because VideoStream applies only to the media streams that have been configured on the WLC. The administrator must specify which video streams should be optimized by VideoStream.
F. The AP replicates the multicast video frames into 802.11 unicast frames to be sent directly to wireless clients at their individual data rate. This statement is also true. VideoStream uses a technique called multicast-to-unicast conversion, which means that the AP replicates the multicast video frames into 802.11 unicast frames that are sent directly to each client at its individual data rate. This technique is more efficient than traditional multicast delivery, as it allows for the optimization of the video stream for each individual client.
A is incorrect because VideoStream applies only to the media streams that have been configured on the WLC.
B is incorrect because VideoStream doesn't enable broadcasting of the video stream using 802.11n HT data rates.
D is incorrect because VideoStream doesn't convert the multicast video stream into unicast to be sent directly to clients at the WLC level.
E is incorrect because VideoStream doesn't rely on receiver clients to acknowledge the 802.11 multicast video data frames on the air to deliver reliable video multicast.
