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

No RPF check means it gets switched, right?

I thought RPF checks were always mandatory?

Definitely goes through if RPF check is good!

Multicast traffic on shared trees can be tricky.

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.

This question seems straightforward, but I want to make sure I understand the details correctly before answering.

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.

I think the answer is C - only authorized users. That seems to be the most straightforward interpretation of the question.

Scalability sounds important, but I'm not sure how it directly relates to threat reduction on surface areas.

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

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.

User 3: Yeah, it seems like option D is not the correct answer. We should probably go with another option.

User 2: I agree, that does seem strange. Maybe it's a mistake in the options.

User 1: I think option D is incorrect. It doesn't make sense to drop multicast traffic based on an RPF check against the receiver.
CH
Cherry

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.

D) It is dropped due to an unsuccessful RPF check against the multicast receiver.
CA

C) It is switched due to a successful RPF check against the routing table
EL

B) It is switched give that no RPF check is performed
DY

A) It is dropped due to an unsuccessful RPF check against the multicast source
JO

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

I agree with Devon, the multicast traffic will be dropped if the RPF check against the multicast source fails.
HU
Hubert

I believe the multicast traffic will be switched since no RPF check is performed.
DE

I think the multicast traffic will be dropped due to an unsuccessful RPF check against the multicast source.
