I have a vague memory of creating an ECS instance from a snapshot, but I can't recall if that's actually allowed. Maybe D is the one that's not correct?

I practiced a similar question, and I think rolling back a disk using a snapshot is definitely possible, so C seems correct.

I recall mentioning the checkbox in settings during my review... so maybe it is A? But I feel like there was something about the config file too... so confused!

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.
