AWS Cloud Practitioner CLF-C02 Practice Question

Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is the best storage class for the described requirements because it is designed for data that is accessed less frequently, but requires rapid access when needed. S3 Standard-IA offers a lower storage cost in comparison to S3 Standard, and while it has a higher retrieval cost, the overall cost is still lower for the infrequently accessed data. S3 One Zone-IA is also less expensive in terms of storage costs, but lacks the resiliency of S3 Standard-IA as it stores data in a single Availability Zone. S3 Glacier (now S3 Glacier Flexible Retrieval) and S3 Glacier Deep Archive are not suitable for the requirements due to their retrieval times which can range from minutes to hours.
