AWS Certified Cloud Practitioner (CLF-C02) — Question 180

A company is storing data that will not be frequently accessed in the AWS Cloud. If the company needs to access the data, the data needs to be retrieved within 12 hours. The company wants a solution that is cost-effective for storage costs for each gigabyte.

Which Amazon S3 storage class will meet these requirements?

Answer options

• A. S3 Standard
• B. S3 Glacier Flexible Retrieval
• C. S3 One Zone-Infrequent Access (S3 One Zone-IA)
• D. S3 Standard-Infrequent Access (S3 Standard-IA)

Correct answer: B

Explanation

The S3 Glacier Flexible Retrieval class is specifically designed for data that is infrequently accessed and allows retrieval within the specified time frame of 12 hours, making it the most cost-effective choice for this scenario. The other options either do not meet the retrieval time requirement (like S3 Standard) or are not as cost-effective for long-term storage (like S3 Standard-IA and S3 One Zone-IA).
