Wait, you can manually create snapshots? That's just like, common sense. What else would you do, automatically create them in your sleep?

Hmm, I see your point. But I still think B) is the correct answer because automatic snapshots are not supported in ECS.

I'd go with option D. You can totally create an ECS instance from a snapshot, that's like a core feature of the service.

I think option C is incorrect. You can't roll back a disk using a snapshot, you can only restore it to a new disk.
