Question 27 of 100 | ← Chapter 10

Q627. A company has a financial application that produces reports. The reports average 50 KB in size and are stored in Amazon S3. The reports are frequently accessed during the first week after production and must be stored for several years. The reports must be retrievable within 6 hours. Which solution meets these requirements MOST cost-effectively?

• A. Use S3 Standard Use an S3 Lifecycle rule to transition the reports to S3 Glacier after 7 days ✓
• B. Use S3 Standard. Use an S3 Lifecycle rule to transition the reports to S3 Standard-Infrequent Access (S3 Standard-IA) after 7 days.
• C. Use S3 Intelligent-Tiering. Configure S3 Intelligent-Tiering to transition the reports to S3 Standard- Infrequent Access (S3 Standard-IA)and S3 Glacier.
• D. Use S3 Standard Use an S3 Lifecycle rule to transition the reports to S3 Glacier Deep Archive after 7 days

Correct Answer: A. Use S3 Standard Use an S3 Lifecycle rule to transition the reports to S3 Glacier after 7 days

Explanation

The correct answer is:A. Use S3 Standard. Use an S3 Lifecycle rule to transition the reports to S3 Glacier after 7 days. Option A provides the most cost-effective solution for meeting the requirements. By using S3 Standard and implementing an S3 Lifecycle rule to transition the reports to S3 Glacier after 7 days, the company can take advantage of the lower storage costs of S3 Glacier for long-term storage. Since the reports are frequently accessed during the first week after production, storing them in S3 Standard, which offers high availability and low latency, ensures that they can be retrieved within 6 hours.Option B is not the best choice:B. Using S3 Standard and transitioning the reports to S3 Standard-IA after 7 days using an S3 Lifecycle rule would incur additional storage costs compared to option A. S3 Standard-IA offers lower storage costs than S3 Standard, but it still has higher costs than S3 Glacier. Since the reports need to be stored for several years, transitioning them to S3 Standard-IA would result in unnecessary additional costs.Option C is not the best choice either:C. Using S3 Intelligent-Tiering and configuring it to transition the reports to S3 Standard-IA and S3 Glacier would also result in higher costs compared to option A. S3 Intelligent-Tiering is useful for automatically optimizing storage costs based on access patterns, but for long-term storage of the reports, transitioning them to S3 Glacier directly provides the most cost-effective solution.Option D is not the best choice either:D. Using S3 Standard and transitioning the reports to S3 Glacier Deep Archive after 7 days would not be suitable for this scenario. S3 Glacier Deep Archive is intended for long-term archival storage with very infrequent access requirements. Retrieving the reports within 6 hours from S3 Glacier Deep Archive would not be feasible.Therefore, the most cost-effective solution that meets the requirements of storing and retrieving the reports is to use S3 Standard and implement an S3 Lifecycle rule to transition the reports to S3 Glacier after 7 days (option A).20%C
