Automatically Transitioning Objects to Low-Cost Storage

Answer: A.

Option A is CORRECT.

Using “Amazon S3 lifecycle policies”, we can set up rules to perform “Transition Actions” and “Expiration Actions”

Transition actions define the rules as to when an object transitions to different storage classes.

Option B is INCORRECT.

S3 versioning enables maintaining multiple versions of an object in one bucket.

Option C is INCORRECT.

Replication enables duplication/copy of objects from one S3 bucket to another S3 bucket, either in the same region or different region.

Option D is INCORRECT.

S3 Batch Operations are used to perform batch operations on objects in S3

Batch operation can perform a single operation on a specified list of S3 objects.

Automatic transition of objects to different storage classes could not be done via S3 batch operations.

The correct answer to this question is A. By configuring “Amazon S3 lifecycle policies.”

Amazon S3 (Simple Storage Service) is an object storage service provided by Amazon Web Services (AWS) that allows customers to store and retrieve data from anywhere on the web. One of the key features of Amazon S3 is the ability to automatically transition objects to appropriate low-cost storage classes at defined intervals using lifecycle policies.

Lifecycle policies are a set of rules that define the lifecycle of objects in Amazon S3. These rules can be used to automate the transition of objects between storage classes or to expire objects after a specific period. By using lifecycle policies, customers can optimize their storage costs by moving less frequently accessed data to lower-cost storage tiers, such as Amazon S3 Standard-Infrequent Access (S3 Standard-IA) or Amazon S3 Glacier.

Lifecycle policies can be configured using the Amazon S3 Management Console, AWS CLI, or AWS SDKs. The policies are based on object age, object size, or a combination of both. Customers can also define the transition action, such as moving objects to S3 Standard-IA after 30 days or moving them to Glacier after 60 days.

In conclusion, by configuring Amazon S3 lifecycle policies, customers can automate the transition of objects between storage classes and optimize their storage costs.
