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 that would 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 would cause 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 reduce multicast 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.
