Hmm, this seems straightforward. I think I'll go with option A and enable Azure Defender at the subscription level to cover all my resources.

Hmm, I'm not totally sure about this one. I'm debating between Mandatory Access Control and Role-Based Access Control. I'll have to think it through a bit more.
