S3 Object Lifecycle Policies

Correct Answer: Create a lifecycle policy that moves the objects to the S3 Standard-Infrequent Access storage class after 30 days and then deletes the objects after 365 days.

The best way to achieve the company's requirements is to create an S3 lifecycle policy. This policy should be configured to transition objects from the standard storage class to the S3 Standard-Infrequent Access (S3 Standard-IA) storage class after 30 days. Then, the same policy should be set to expire (delete) the objects after 365 days. This approach automates the process, ensuring cost-efficiency by moving less frequently accessed data to a cheaper storage tier before eventual deletion. It precisely meets the company's needs for both transitioning storage classes and object deletion at the specified intervals. None of the provided options correctly address both the transition to infrequent access storage and the deletion requirement, hence a new correct answer is necessary.

Correct Answer: Configure a lifecycle policy to transition objects to S3 Glacier after 3 months.

Configuring a lifecycle policy to transition objects to S3 Glacier after 3 months is the best approach to archive the log files while meeting their retention requirement.

Correct Answer: Create an S3 Lifecycle policy to transition objects to One Zone-Infrequent Access after 60 days and another action to delete after 180 days.

Use Amazon S3 Lifecycle rules to automatically manage object transitions and expiration based on object age. Configure a lifecycle rule that transitions objects to S3 One Zone-Infrequent Access at 60 days (which meets the minimum 30-day requirement before moving into an IA class) and sets an expiration to permanently delete the objects at 180 days. This approach is fully managed, scalable, cost-effective, and precisely targets the specified storage class and timing without custom code or manual operations.
