AWS Certified Cloud Practitioner — Question 667

A company must archive Amazon S3 data that the company's business units no longer need to access.

Which S3 storage class will meet this requirement MOST cost-effectively?

Answer options

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

Correct answer: C

Explanation

Amazon S3 Glacier Deep Archive is the lowest-cost storage class in AWS, making it the most cost-effective option for long-term archiving of data that no longer needs to be accessed. S3 Glacier Instant Retrieval and S3 Glacier Flexible Retrieval are more expensive storage options designed for faster data retrieval. S3 One Zone-Infrequent Access is intended for infrequently accessed data and has significantly higher storage costs compared to Glacier archiving classes.
