You have a lifecycle rule for an S3 bucket that archives objects to the S3 Glacier storage class 60 days after creation. The archived objects are no longer needed one year after being created. How would you configure the S3 bucket to save more cost?

Answer options:

A.Configure a rule in S3 Glacier to place delete markers for objects that are one year old.
B.Configure the S3 lifecycle rule to expire the objects after 365 days from object creation.
C.Modify the S3 lifecycle rule to clean up expired object delete markers for one year old objects.
D.Modify the S3 lifecycle rule to use S3 Glacier Deep Archive which automatically deletes objects one year after creation.

Correct Answer – B
Users can configure the expiration actions in S3 lifecycle management. Details can be found in https://docs.aws.amazon.com/AmazonS3/latest/dev/object-lifecycle-mgmt.html.
Option A is incorrect: Because users cannot configure a rule to place delete markers in S3 Glacier.
Option B is CORRECT: Because users can configure the object expiration in the S3 life cycle, Amazon S3 will remove the expired objects.
Option C is incorrect: Because cleaning up expired object delete markers does not expire the objects. This action does not save costs.
Option D is incorrect: Because S3 Glacier Deep Archive does not automatically delete objects.
