Yeah, if SSM isn't enabled, IGMPv1 and v2 can't do much.

I’m pretty sure that IGMP hosts can run SSM services with IGMPv3, so option C seems correct to me, but I’m not 100% confident.

I practiced a similar question about IGMP versions, and I feel like option D could be misleading since SSM might still work without enabling that feature.

I think option A sounds off because I recall the SSM range is usually 232.0.0.0 to 232.255.255.255, but I need to double-check that.

I remember that IGMPv3 is crucial for SSM, but I'm not entirely sure if it processes messages from the earlier versions.

Hmm, I'm a bit unsure about this one. The question mentions the system time being off by more than 12 hours, so it's clearly a time-related issue. But I'm not sure if NTP is the only protocol used for time synchronization on Linux. I'll have to think this through carefully.

The Monitoring Console is for monitoring the whole cluster, right? So it should be on the License master that has 50 or more clients, since that's the central point.

This seems pretty straightforward. I think the answer is collections, since that's how you group related apps in the My Apps portal.
