You want to enable multicast video streaming supporting multicast for both wired and wireless
clients. Which two statements are true regarding the design 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 and receive 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 unique challenge 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 queues by means of the 802.11e UP value.
