Wait, it can just be dropped? That’s wild!

No RPF check means it gets switched, right?

D sounds familiar too, but I can't remember if it specifically relates to the multicast receiver or not.

I'm leaning towards C because I recall that a successful RPF check means the traffic is allowed through, but I could be mixing it up.

I remember practicing a similar question where multicast traffic was switched if no RPF check was performed, so maybe B is correct?

I think the answer might be A, but I'm not completely sure about the RPF check details.

This looks like a classic multicast routing question. I'll apply my knowledge of RPF checks and shared trees to eliminate the incorrect options and select the right answer.

Okay, I think I've got this. The key is to focus on the RPF (Reverse Path Forwarding) check and how that affects the multicast traffic on the shared tree.

Hmm, the exhibit shows a network diagram, so I'll need to carefully analyze the information provided to determine the multicast behavior.

I'm a bit confused about the shared tree (*,G) concept. I'll need to review my notes on multicast routing to make sure I'm applying the right principles here.

Option F: The multicast traffic is transformed into glitter and confetti, raining down on the unsuspecting network engineers. It's a multicast party!

Option B is tempting, but I think the question is looking for a more specific answer. No RPF check doesn't sound quite right.

Option D is just weird. Why would it be dropped due to an RPF check against the multicast receiver? That doesn't seem right.

Option A seems incorrect. The question states it's received on the LHR interface, so there shouldn't be an unsuccessful RPF check against the source.

Option C makes the most sense. If the RPF check against the routing table is successful, the multicast traffic should be switched.
