Cost-Optimized Architecture I

Question 39

A SaaS company uses Amazon S3 to store large amounts of data uploaded by users. The data includes frequently accessed files whose access patterns might change over time, as well as files that are rarely accessed but need to be retained for compliance reasons. The company wants to reduce storage costs while ensuring that frequently accessed files remain readily available.

As a solutions architect, recommend a cost-optimized storage solution for the data in Amazon S3.

A. Store all data in Amazon S3 Standard to ensure quick access to all files regardless of access frequency.

B. Use Amazon S3 Intelligent-Tiering to automatically move objects between two access tiers (frequent and infrequent).

C. Implement life cycle policies to transition older files to Amazon S3 Glacier for cost savings.

D. Store frequently accessed files in Amazon S3 Standard and infrequently accessed files in Amazon S3 One Zone-IA to reduce costs.
