A VPLS network consists of provider edge routers that have fully meshed pseudowires, the network runs unicast and multicast traffic, the network recently experienced bandwidth and CPU-related performance issue While monitoring the VPLS and interface statistics an operations engineer notice that the network is experiencing an unusual amount of broadcast and undesired multicast traffic.

Which two technique can address these issue? (Choose two)
A . Change the network to run VPWS to mange the broadcast traffic efficiently
B . Implement MAC withdrawal on each EFP in the VPLS bridge domain
C . Set a limit on MAC learning in the pseudowire in the VPLS network
D . Implement Storm Control in the VPLS bridge domain
E . Implement IGMP snooping in the VPLS network
