You want to enable multicast video streaming supporting multicast for both wired and wireless clients. Which two statements are true regarding thedesign of the network to deliver multicast streams over wireless? (Choose two.)
A. Multicast and broadcast packets cannot be managed because wireless clients will use the lowest mandatory rate supported by each AP to send andreceive traffic.
B. Multicast and broadcast packets do not send out ACK messages, and all packets are being delivered via best effort.
C. Multicast over wireless relies on a TCP retransmission mechanism for reliable transmission, which explains why multicast presents a uniquechallenge for media traffic because multicast video is mostly UDP traffic.
D. A wireless network does not provide reliable transmission for multicast packets and does not classify queues or provision QoS.
E. IGMPv3 is required to provide reliable transmission for multicast streams. The default 802.11 retransmission mechanism will prioritize WMM queuesby means of the 802.11e UP value.
