A company needs to store images that are uploaded by users via a mobile application. There is also a need to ensure that security measures are in place to avoid data loss.
What step should be taken for protection against unintended user actions?
 

Answer options:

A.Store data in an EBS volume and create snapshots once a week.
B.Store data in an S3 bucket and enable versioning.
C.Store data on Amazon EFS storage.
D.Store data on EC2 instance storage.

Correct Answer - B
Amazon S3 has an option for versioning, as shown below. Versioning is on the bucket level and can be used to recover prior versions of an object.

Option A is incorrect as it does not offer protection against accidental deletion of files. 
Option C is incorrect. It is not the ideal solution because multiple EC2 instances can access the file system.
Option D is ephemeral.
