I'm just going to go with the flow and pick C. I mean, who doesn't love a little IGMPv3 action, am I right?

The answer is definitely B. IGMP SSM Mapping is all about supporting older versions of IGMP, not the fancy new IGMPv3.

No, I disagree. The correct answer is C. IGMP hosts can use SSM services with IGMPv3 on the multicast router socket.

This is a tough one, but I'm going to go with C. IGMP hosts can use IGMPv3 to access the SSM services on the multicast router, right?

I don't know, this question seems a bit tricky. Maybe the answer is A? I thought the SSM multicast range was 232.0.0.0 to 232.255.255.255.

I agree with Karan, option B is definitely wrong. IGMP SSM Mapping does support IGMPv3 for SSM services.

I believe option B is incorrect because IGMP SSM Mapping does process reporting messages from IGMPv3.

Hmm, I was leaning towards D. If IGMP SSM Mapping isn't enabled, then IGMPv1 and IGMPv2 can't use the SSM services, right?

I'm pretty sure the answer is B. IGMP SSM Mapping doesn't process IGMPv3 reports, it's designed for IGMPv1 and IGMPv2 to access SSM networks.
