AWS Certified Cloud Practitioner (CLF-C02) — Question 446

A company stores a large amount of data that auditors access only twice each year.

Which Amazon S3 storage class should the company use to store the data with the LOWEST cost?

Answer options

• A. Amazon S3 Outposts
• B. Amazon S3 Glacier Instant Retrieval
• C. Amazon S3 Standard
• D. Amazon S3 Intelligent-Tiering

Correct answer: B

Explanation

Amazon S3 Glacier Instant Retrieval is the most cost-effective option for archiving data that is accessed only a few times a year but requires millisecond retrieval. Amazon S3 Standard is designed for active, frequently accessed data and has higher storage costs. Amazon S3 Intelligent-Tiering is ideal for data with changing or unpredictable access patterns, whereas this workload has a highly predictable, infrequent access pattern.
