A company has an application that stores images and thumbnails on S3. The thumbnail needs to be available for download immediately. Additionally, both the images and thumbnails are not accessed frequently. What would be the cost-efficient storage option that meets the above-mentioned requirements?

Answer options:

A.Amazon Glacier with Expedited Retrievals.
B.Amazon S3 Standard Infrequent Access
C.Amazon EFS
D.Amazon S3 Standard

Correct Answer – B
Amazon S3 Infrequent access is perfect if you want to store data that is not frequently accessed. It is more cost-effective than Option D (Amazon S3 Standard). If you choose Amazon Glacier with Expedited Retrievals, you defeat the whole purpose of the requirement because of its increased cost.
