I thought it would forward it to Router D, but I guess not!

Wait, are you sure about that? I thought it might forward it instead.

Router B will discard the register message due to the RPF-check failing.

I feel like option D might be correct since it mentions the specific entry for the multicast group. But I need to double-check the RPF-check rules.

I'm a bit confused about the routing table's role in this scenario. Wouldn't Router B just forward the message to the RP if it was valid?

I remember a similar question where the RPF-check was a deciding factor. I feel like option A could be the right answer.

I think the RPF-check is crucial here, so if it fails, Router B would discard the register message. But I'm not entirely sure.

Hmm, I'm a little unsure about this one. I'll need to carefully read through the steps to make sure I get it right.

This seems like a straightforward question about Scrum roles. I'll think through the key responsibilities of each role and consider which ones should be cross-functional.
