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!
