I disagree, I feel like it could be D depending on the setup.

Definitely A, that's how PIM works in ASM.

Wait, how does Router D's RPF table affect this? Sounds complicated!

I think it's A, both routers will send the Join.

I vaguely recall that both routers might send the Join if they are both on the path to the RP, but I can't remember the specifics. This is tricky!

I’m a bit lost on this one. Does it depend on the RPF configuration? I feel like I need to double-check how the RPF table works in this scenario.

I think I saw a similar question where it asked about how routers handle multicast joins, and it was clear that only one router typically sends the Join to the RP.

I remember that in PIM ASM, when a receiver joins, the routers need to send a Join message to the RP, but I'm not sure if both routers do it or just one.

This is a good test of my PIM ASM knowledge. I'll need to carefully consider the role of each router and how they'll respond when a receiver joins the multicast channel.

I'm feeling pretty confident about this one. The exhibit shows a typical PIM ASM network, so I should be able to apply my understanding of the protocol to select the right answer.

Okay, I think I've got this. The key is to identify the RPF neighbor for the RP in Router D's table. That will determine which router(s) send the join.

Hmm, I'm a bit confused by the different options. I'll need to review my PIM ASM knowledge to determine which router(s) will propagate the join to the RP.

This question seems similar to one we practiced where we had to change an event trigger. I think it was about using "onload" too.

Option B is just too simple. In a PIM ASM network, you know the multicast routing is gonna be a complex dance between the routers. I'm going with option A.

I'm torn between options A and D. I think it really depends on Router D's RPF table, as mentioned in option D.
