AWS Certified Solutions Architect – Associate (SAA-C02) — Question 94

A company is processing data on a daily basis. The results of the operations are stored in an Amazon S3 bucket, analyzed daily for one week, and then must remain immediately accessible for occasional analysis.
What is the MOST cost-effective storage solution alternative to the current configuration?

Answer options

• A. Configure a lifecycle policy to delete the objects after 30 days.
• B. Configure a lifecycle policy to transition the objects to Amazon S3 Glacier after 30 days.
• C. Configure a lifecycle policy to transition the objects to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.
• D. Configure a lifecycle policy to transition the objects to Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA) after 30 days.

Correct answer: C

Explanation

The correct answer, C, is optimal because Amazon S3 Standard-IA is designed for data that is less frequently accessed but still requires immediate availability, making it cost-effective. Options A and B do not provide immediate access after the initial analysis period, while D may be cheaper but lacks the redundancy and higher availability of S3 Standard-IA.
