I thought the group address was different, this is confusing.

The I-PMSI group address is actually 232.10.10.0.

I think A is the false one, GRE tunnels don’t instantiate S-PMSI.

Wait, 192.168.1.2 as a multicast source? That seems off.

I’m pretty certain that 192.168.1.2 is a common private IP address, but I can't remember if it was used as a multicast source in the examples we went over.

I'm a bit confused about the multicast group addresses. I feel like 239.1.1.1 is a valid multicast group, but I can't recall if it was specifically mentioned in our materials.

I practiced a similar question where the I-PMSI address was mentioned, and I think it was always in the 232.x.x.x range, so B seems true.

I think I remember that GRE tunnels are used for encapsulating multicast traffic, but I'm not completely sure if that's the S-PMSI or I-PMSI.

Okay, I see the key information in the image. Now I just need to analyze each answer choice and identify the one that doesn't match the output.

I agree with Casey, 192.168.1.2 is the IP address of the multicast source.

Haha, these options are a real mixed bag! I'm pretty sure the S-PMSI and the source IP are right, but this I-PMSI group address and customer multicast group? Someone's been hitting the coffee a little too hard, if you ask me.

Hmm, the IP address of the multicast source is clearly 192.168.1.2, no doubt about that. But this customer sending traffic to 239.1.1.1? That's a head-scratcher, if you ask me.

The S-PMSI is definitely instantiated by GRE tunnels, that's a no-brainer. But what's with this 232.10.10.0 business? Sounds like someone needs to double-check their multicast addresses.
