Question 470
An HPE Aruba Networking engineer faces this wired-network scenario: Receivers on a remote multicast VLAN lose only the video stream after an uplink change. Which implementation action BEST addresses the requirement?
Explanation
Correct Answer
Multicast route distribution depends on control plane and reverse path correctness. The targeted implementation is to restore valid PIM neighbor or reverse-path reachability for the multicast group. The deployment succeeds when multicast forwarding state and receiver stream return while unicast remains stable.
Incorrect Answers
This implementation choice fits a different situation: An aggregated uplink loses half its capacity after a peer switch update. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to restore valid PIM neighbor or reverse-path reachability for the multicast group.
This implementation choice fits a different situation: A dual gateway pair both appear as active masters after a configuration change. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to restore valid PIM neighbor or reverse-path reachability for the multicast group.
This implementation choice fits a different situation: An uplink stops after a maintenance crew replaces a single transceiver. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to restore valid PIM neighbor or reverse-path reachability for the multicast group.
