A new IPv4 multicast-based video-streaming service is being provisioned. During the designvalidation tests, you realize that the link between the two buildings is carrying multicast traffic
even when there are no receivers connected to the switch in Building B and despite IGMPsnooping being enabled on both Layer 2 switches and IGMPv2 runs on the hosts. Which design
change will prevent the multicast trafficfrom being unnecessarily flooded throughout the
campus network?

A.
Enable PIM snooping on both Layer 2 switches.

B.
Enable multicast storm control on the link between Switch 1 and Switch 2.

C.
Use static Layer 2 MAC forwardingentries on Switch 1.

D.
Change the IPv4 multicast group address such that it excludes the usage of link-local MAC
addresses.

E.
Ensure that Switch 1 is an IGMP querier.
