Explanation
S3 Versioning is the correct answer because it allows you to:
- Preserve multiple versions of objects in the same S3 bucket
- Recover from accidental deletion - when you delete an object, S3 simply adds a delete marker instead of permanently removing the object
- Restore overwritten objects - when you overwrite an object, the previous version is preserved and can be restored
- Enable point-in-time recovery of your data
Why the other options are incorrect:
- S3 Access Points: Manages data access at scale with unique hostnames and access policies
- S3 Block Public Access: Provides centralized controls to block public access to S3 buckets
- S3 Object Lock: Prevents object deletion/modification for compliance and retention purposes, but doesn't help with accidental deletion recovery
S3 Versioning is specifically designed for data protection and recovery scenarios where you need to restore previous versions of objects or recover from accidental deletions.
