True, but HA doesn't guarantee zero data loss like Fault Tolerance does.

I’m leaning towards Fault Tolerance too, but I wonder if there are nuances I might be missing from the study materials.

I practiced a similar question, and I feel like vMotion is more about live migration, so it can't be the answer.

I’m not entirely sure, but I remember something about vSphere High Availability helping with VM restarts, not necessarily zero data loss.

I think it might be Fault Tolerance since it’s designed to keep the VM running without any data loss during a failure.
