Correct answer & explanation
✓
Examine source IP address of multicast packet
The RPF check ensures that incoming multicast packets arrive on the correct interface toward the source. First, the router examines the source IP address. Then it consults the unicast routing table to find the best route. It identifies the outgoing interface for that route. It compares that interface with the arrival interface of the multicast packet. If they match, the packet is forwarded; otherwise, it is dropped.
