SAP-C02 Question 343
Single answerA company is running a data analytics workload on AWS that processes large volumes of data. The data is accessed frequently for the first 30 days and then rarely accessed afterward. The company wants to minimize storage costs while ensuring the data is still available for future analytics. Which solution would best meet the requirements?
- A
Store the data in Amazon S3 Standard and transition it to S3 Glacier Flexible Retrieval after 30 days using lifecycle policies.
- B
Store the data in Amazon S3 Intelligent-Tiering to automatically optimize storage costs based on access patterns.
- C
Store the data in Amazon S3 Standard and delete it after 30 days to save costs.
- D
Store the data in Amazon S3 Standard-IA immediately to reduce storage costs.
Show answer and explanation
Correct answer: B
Explanation
The S3 Intelligent-Tiering storage class is ideal for the given scenario because it automatically moves data between frequent access and infrequent access tiers based on usage patterns. This eliminates the need to manually create lifecycle policies and ensures cost savings while maintaining accessibility. The other options either fail to meet the access requirements or are not cost-efficient for the workload described.
- A. Incorrect.
This option is incorrect because S3 Glacier Flexible Retrieval is designed for archival storage, and retrieving data from it incurs higher latency and retrieval costs. The data is still accessed frequently in the first 30 days, so this would not be cost-effective.
- B. Correct.
This is the correct answer because S3 Intelligent-Tiering automatically moves data between tiers based on changing access patterns, providing cost optimization without impacting performance or operational overhead. It is well-suited for workloads with unpredictable or changing access patterns.
- C. Incorrect.
This option is incorrect because deleting the data after 30 days does not meet the requirement of retaining it for future analytics.
- D. Incorrect.
This option is incorrect because S3 Standard-IA is suitable for data that is accessed less frequently but requires immediate retrieval. However, the data is frequently accessed in the first 30 days, making S3 Standard-IA less cost-effective and not optimal for this scenario.
