SAP-C02 Question 346
Select 3A company has a highly dynamic workload where data is frequently accessed for a short period and then rarely accessed afterward. They want to optimize storage costs while ensuring that infrequently accessed data is still available when needed. Which of the following solutions should you implement to achieve cost optimization using storage tiering?
- A
Configure Amazon S3 Intelligent-Tiering for the data to automatically move between tiers based on access patterns.
- B
Use Amazon S3 Standard for frequently accessed data and manually transition unused data to S3 Glacier Deep Archive.
- C
Enable lifecycle policies in Amazon S3 to transition data from S3 Standard to S3 Infrequent Access (S3 IA) and then to S3 Glacier.
- D
Implement Amazon EFS lifecycle management to move infrequently accessed files to the Infrequent Access storage class.
- E
Store all data in Amazon S3 One Zone-Infrequent Access to lower costs for infrequently accessed data.
Show answer and explanation
Correct answers: A, C, D
Explanation
For dynamic workloads with unpredictable access patterns, automated storage tiering is essential to optimize costs without sacrificing availability. Amazon S3 Intelligent-Tiering is ideal for automatically managing access patterns, while lifecycle policies in S3 and EFS lifecycle management provide automated transitions to cost-efficient storage classes for infrequently accessed data. These solutions minimize operational overhead and ensure data remains available when needed.
- A. Correct.
Correct. Amazon S3 Intelligent-Tiering automatically moves data to the most cost-effective tier based on access patterns, making it ideal for dynamic workloads with unpredictable access patterns.
- B. Incorrect.
Incorrect. Manually transitioning data between tiers increases operational overhead and is prone to mismanagement. It is not the most cost-effective or efficient approach for this scenario.
- C. Correct.
Correct. Lifecycle policies in Amazon S3 can automatically transition data between storage classes, such as from S3 Standard to S3 IA and then to S3 Glacier, optimizing costs for infrequently accessed data.
- D. Correct.
Correct. Amazon EFS lifecycle management can automatically move infrequently accessed files to the Infrequent Access storage class, reducing costs for file-based workloads.
- E. Incorrect.
Incorrect. Storing all data in Amazon S3 One Zone-Infrequent Access is risky and does not meet the requirement for ensuring availability, as it stores data in a single Availability Zone, which is less reliable.
