An engineer has eight WLCs in a mobility group and must reduce the bandwidth consumed. Which two configuration items achieve this result? (Choose two.)
Global multicast mode (A) helps optimize network traffic by sending a single multicast stream instead of multiple unicast packets, which is particularly useful in large networks.
Mobility group multicast messaging (D) ensures that WLCs exchange mobility information efficiently, further minimizing bandwidth consumption.
Other options:
B. Mobility group unicast messaging increases bandwidth usage since messages are sent individually to each WLC.
C. Global unicast messaging is less efficient than multicast and increases traffic.
E. Global symmetric mobility messaging is related to client mobility between controllers but does not directly impact bandwidth optimization.
A is correct:
Multicast Mode optimizes the controller's efficiency as it sends only a single copy of multicast data to the multicast group address instead of sending one copy to each and every subscribed AP.
D is also correct:
you need first to enable multicast.
then enable mutlicast on the mobility group.
