Development teams in your organization use S3 buckets to store the log files for various applications hosted in development environments in AWS. The developers want to keep the logs for one month for troubleshooting purposes and then remove the logs.
What feature will enable this requirement?
 

Answer options:

A.Adding a bucket policy on the S3 bucket.
B.Configuring lifecycle configuration rules on the S3 bucket.
C.Creating an IAM policy for the S3 bucket.
D.Enabling CORS on the S3 bucket.

Answer: B
Option A is incorrect because adding bucket policies cannot control the deletion of logs.
Option B is CORRECT because Lifecycle configuration enables you to specify the lifecycle management of objects in a bucket, logs in this case. We can use expiration actions – In which you specify when the objects expire. Then Amazon S3 deletes the expired objects on your behalf.
Option C is incorrect because creating an IAM policy cannot control the deletion of logs.
Option D is incorrect because CORS is used for accessing objects across domains and not for the deletion of logs.
