Actual exam question for Huawei's H12-261_V3.0 exam

Question #: 52
Topic #: 4

RTA is the source DR router and RTB is the RP router. The multicast source sends multicast data to the RIA, but the RIB cannot see the multicast source registered to it through the PIM Register message. What are the possible reasons?

AThere is no unicast route from RTB to RTA, which causes RTB to fail the RPF check of the source.

BThe multicast network dynamically elects RP, and RTA fails to check the RPF of BSR.

CThe RP elected by RTA is not RTB

DThe RP is statically configured on the multicast network, while the RTA router is not statically configured with the RP

Ah, the age-old static RP vs. dynamic RP dilemma. If the RP is statically configured, then option D seems like the way to go. Let's hope the network admin isn't sleeping on the job!

Maybe the network admin needs to double-check the configurations to avoid any problems.

Yeah, having the RP statically configured can definitely cause issues.

Option D seems like the best choice if RP is statically configured.

Haha, the RP better not be a diva and refusing to work with RTA! Option C could be the answer, but I'm not totally sure.

Option C says the RP elected by RTA is not RTB, so that could be the reason.

Yeah, that could be the case. It might not be configured to work with RTA.

Maybe the RP is just being picky and not wanting to work with RTA.

Yeah, if the RP is not RTB, then that could definitely cause issues with the multicast data not being seen by RIB.

Hmm, interesting. Maybe the dynamic election of the RP is the issue? I'm leaning towards option B, but I'll have to think this through a bit more.

I think it could be a combination of options A and D, depending on the network setup.

The problem seems to be with the RPF check. The lack of a unicast route from RTB to RTA is the likely culprit here. I'd go with option A.

Yes, without a proper unicast route, the RPF check will fail and cause issues with multicast data flow.

I agree, option A makes sense. The RPF check is crucial for multicast routing.

I'm not sure, but option D also seems plausible since RTA might not be configured with the RP.

I agree with Gilma, option A makes sense because of the RPF check.
