A customer recently implemented WLC wireless multicast. Clients and connecting at the highest mandatory wireless rate of 24 Mbps and are receiving multicast traffic, but WLC cpu utilization and wired side network load has increased substantially. What three actions should the engineer take next to optimize the configuration? (Choose Three)

Clients and connecting at the highest mandatory wireless rate of 24 Mbps and are receiving multicast traffic, but WLC cpu utilization and wired side network load has increased substantially. What three actions should the engineer take next to optimize the configuration? (Choose Three)
A . verify that Global Multicast mode has been enabled
B . verify that IGMP snooping is disabled on the wireless controller since the access points are handing IGMP messages from the clients.
C . make sure the highest mandatory rate is set to 54 Mbps so that the multicast traffic has sufficient bandwidth
D . verify Multicast Listener Discovery (MLD) v1 snooping has been enabled to keep track of and deliver IPv4 multicast flows
E . change the wireless controller from Multicast-Unicastmodeto Multicast-Multicast mode and assign a multicast address in the 239.
G . X/8 subnet
H . verify that the L3 interfaces are configured for pirn sparse-dense-mode on the VLAN servicing the wireless access points as well as the wireless controller’s management VLAN
