What does S3 Versioning let an owner do with an object?

  1. Compress older copies to reduce cost
  2. Lock it against deletion for a fixed retention period
  3. Preserve, retrieve and restore every version of it in the same bucket
  4. Store it across two Regions automatically
Show the answer

Answer: C. Preserve, retrieve and restore every version of it in the same bucket

Versioning keeps multiple variants of an object in one bucket, which is what makes recovery from user error or application failure possible.
