I feel like we had a similar question on the last practice exam, and I think the correct approach was to use the filter method effectively, like in option C.

I think option C looks familiar; it uses RDDs and seems to follow the logic we discussed in class about aggregating data.

Hmm, I'm a bit unsure about this one. I know enterprise networking involves things like LANs and WANs, but I'm not sure if that's the full answer. I'll have to think this through carefully.

Okay, let me break this down. The Act is meant to provide transparency in public authorities, so I'm guessing it wouldn't cover the high courts or state legislatures since they have their own processes. I'll go with B for now, but I'm not 100% sure.
