To support efficient bandwidth utilization for broadcasting multicast packets to all WLANs on the AP, which two mechanisms can you configure on the Cisco WLCs? (Choose two.)
A. VideoStream can be used to convert multicast transmissions to broadcast transmissions at the AP, to enable the AP to receive ACKs from the clients and to determine the frames that need to be retransmitted.
B. VideoStream can be used to convert multicast transmissions to unicast transmissions at the AP. The same data rate will be used, but the unicast stream allows the AP to receive ACKs from the clients and to determine the frames that need to be retransmitted.
C. RRC in a Cisco WLC will use channel utilization as a metric to determine capacity and perform admission control, but it does not deny requests thatwould cause oversubscription.
D. RRC in a Cisco WLC will use channel utilization as a metric to determine capacity and perform admission control, and it denies requests that wouldcause oversubscription by sending SAP messages to clients on drop.
E. VideoStream can be used to convert multicast transmission to unicast transmission at the AP. Because of the unreliable nature of wireless media, no ACKs are expected from the clients; however, unicast transmission will effectively reducemulticast PLR to between 0.1 and 0.5 percent.
F. VideoStream can be used to convert multicast transmission to unicast transmission at the AP, to enable the AP to receive ACKs from the clients and to determine the frames that need to be retransmitted.
