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 IGMP snooping
being enabled on both Layer 2 switches and IGMPv2 runs on the hosts. Which design change will
prevent the multicast traffic from 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 forwarding entries 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.
