In your organization, development teams use S3 buckets to store log files for various applications hosted in AWS development environments. The developers intend to keep the logs for a month for troubleshooting purposes and subsequently purge the logs.
Which feature should be used to 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.

Correct Answer – B
AWS Documentation mentions the following on Lifecycle policies:
Lifecycle configuration enables you to specify the Lifecycle management of objects in a bucket. The configuration is a set of one or more rules, where each rule defines an action for Amazon S3 to apply to a group of objects. These actions can be classified as follows:
Transition actions – In which you define when objects transition to another storage class. For example, you may choose to transition objects to the STANDARD_IA (IA, for infrequent access) storage class 30 days after creation or archive objects to the GLACIER storage class one year after creation.
Expiration actions – In which you specify when the objects expire. Then, Amazon S3 deletes the expired objects on your behalf.
