Refer to the exhibit. The receiver is listening to multicast group 239.200.0.1, but no packets are received for the requested multicast group. Which action resolves the issue?

The correct answer is B. Change the port-security violation action to restrict on interface Eth1/2. In this scenario, port-security is configured on both interfaces, but the violation action on Eth1/2 is set to shutdown, which disables the interface when a violation occurs. Since the multicast traffic is likely causing a port security violation, the interface is shutting…

Explanation

In this scenario, port-security is configured on both interfaces, but the violation action on Eth1/2 is set to shutdown, which disables the interface when a violation occurs. Since the multicast traffic is likely causing a port security violation, the interface is shutting down, preventing the receiver from receiving the multicast traffic. Changing the port-security violation action to restrict on Eth1/2 will allow the interface to remain up while still restricting unauthorized MAC addresses, thus resolving the issue and enabling multicast traffic to flow to the receiver.
