Wait, can they really handle data center faults? Sounds too good to be true.

I think multi-zone clusters do provide better disaster recovery, but I'm not completely sure if that's the only advantage.

Hmm, I'm a little unsure about this one. I know the fat-soluble vitamins, but I can't remember if B is included in that group. I'll have to think this through carefully.

I'm feeling pretty confident about this one. The key is to focus on the update function and the permissions it requires.

Okay, let me think this through. I believe the key is to use the Loopback processing mode, which will apply the policy to the user regardless of the policies applied at lower levels. I'm pretty confident that's the right approach.
