A financial institute is storing all its critical documents in the Amazon S3 bucket which has versioning enabled. The retention period is applied to documents using object lock, but you are observing some objects are getting overwritten. Which of the following could be a possible reason?

Answer options:

A.Object should have both retention period & legal hold to prevent from overwriting.
B.Object locks apply to a specific version of an object in a versioned bucket.
C.Object lock should be applied at bucket level to prevent all objects in a bucket from overwriting.
D.Object locks need to apply to all versions of the objects in a versioned bucket.

Correct Answer – B
Object Lock is applied to a specific version of an object. So, if there are multiple versions of an object, users can overwrite objects which do not have an object lock applied to them.
Option A is incorrect as Both Retention period & Legal Hold is not required for an object lock.
Option C is incorrect as Object locks are not applied at bucket level but specific versions of objects.
Option D is incorrect as Object Lock is applied to specific versions of an object & not necessary to all versions of an object.
