Question 280
A first repair attempt for this situation failed: Multicast must reach receivers beyond the source's local routed subnet. The review found the mistaken approach of assuming IGMP snooping alone routes multicast between IP subnets. Which targeted recovery action BEST restores the intended design?
Explanation
Correct Answer
Correct PIM or RPF reachability and recheck multicast forwarding state. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when receiver groups join across routed boundaries through expected multicast state.
Incorrect Answers
This remediation choice fits a different situation: Multicast video receivers report excess streams on their access VLAN. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to correct PIM or RPF reachability and recheck multicast forwarding state.
This remediation choice fits a different situation: A fiber uplink between two buildings never reaches operational up state. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to correct PIM or RPF reachability and recheck multicast forwarding state.
This remediation choice fits a different situation: An operations team wants a switch event to trigger external incident handling. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to correct PIM or RPF reachability and recheck multicast forwarding state.
