How does S3 versioning protect against an accidental delete?

  1. The object is moved to S3 Glacier Deep Archive
  2. A delete marker becomes the current version, leaving the earlier version restorable
  3. The object is copied to a recycle bin bucket
  4. The delete is refused unless MFA is supplied
Show the answer

Answer: B. A delete marker becomes the current version, leaving the earlier version restorable

In a versioned bucket a delete inserts a marker rather than removing the object, so the previous version can be recovered.
