Refer to the exhibit. A new IPv4 multicast-based video-streaming service is being provisioned. During the design-validation 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.
