A) DNS Sinkholing requires the Vulnerability Protection Profile be enabled.
B) Sinkholing malware DNS queries solves this visibilty problem by forging responses to the client host queries directed at fake domains created in a controlled 'Fake Internet' called Zanadu which designed for testing and honeypots.

Wait, does sinkholing really need a special license? Sounds sketchy.

I vaguely remember something about needing a license for sinkholing, but I can't recall if it was a SinkHole license or something else entirely.

I practiced a similar question about DNS sinkholing, and I feel like the idea of a 'Fake Internet' was mentioned, but I'm not confident about the specifics of Zanadu.

I think option C sounds familiar because it aligns with how we identify infected hosts in practice questions, but I can't recall the exact details.

I remember reading that sinkholing helps with visibility issues, but I'm not sure if it specifically requires the Vulnerability Protection Profile to be enabled.

Ah, I see. DNS sinkholing creates a fake 'Zanadu' internet to redirect and monitor malware traffic. Option B describes that process, so I think that's the right answer.

The key here is that DNS sinkholing is used to identify infected hosts when the firewall can't see the originating DNS queries. Option C seems to capture that idea well, so I'll go with that.

A is definitely wrong - the Vulnerability Protection Profile has nothing to do with DNS sinkholing. Sounds like someone just threw that in there to confuse us.

D can't be right, why would you need a special license just to set up a sinkhole? That's overkill.
