SAP-C02 Question 310
Single answerA company is running a data analytics workload that requires high-throughput access to large datasets stored on Amazon S3. Occasionally, the workload needs to process archived data that is infrequently accessed but must remain available within minutes when requested. The company wants to minimize storage costs while meeting these requirements. Which storage class configuration should you recommend?
- A
Store frequently accessed data in S3 Standard and archive infrequently accessed data in S3 Glacier Deep Archive.
- B
Store frequently accessed data in S3 Standard and infrequently accessed data in S3 Intelligent-Tiering.
- C
Store frequently accessed data in S3 Standard-IA and infrequently accessed data in S3 Glacier Flexible Retrieval.
- D
Store frequently accessed data in S3 Standard and infrequently accessed data in S3 Standard-IA.
Show answer and explanation
Correct answer: B
Explanation
S3 Intelligent-Tiering is the most suitable option in this scenario because it automatically optimizes storage costs by moving data between access tiers based on access patterns. It ensures that frequently accessed data remains readily available while infrequently accessed data is stored in lower-cost tiers, including an archive tier with rapid retrieval. This meets the requirements for high-throughput access to frequently used data and cost-effective storage for archived data that must remain available within minutes.
- A. Incorrect.
S3 Glacier Deep Archive is the lowest-cost storage class, but it is designed for data that can tolerate retrieval times of up to 12 hours, which does not meet the requirement to retrieve data within minutes.
- B. Correct.
S3 Intelligent-Tiering automatically moves data to the most cost-effective storage tier based on access patterns. It supports frequent, infrequent, and archived access tiers while ensuring rapid access to data when needed. This meets the requirement for minimizing costs and retrieving archived data within minutes.
- C. Incorrect.
S3 Glacier Flexible Retrieval offers faster retrieval times than Glacier Deep Archive but is still designed for archival data that does not require frequent access. It is not the most cost-effective solution when compared to Intelligent-Tiering for the described use case.
- D. Incorrect.
S3 Standard-IA is a good choice for infrequently accessed data but does not provide the automatic optimization for cost and access patterns that S3 Intelligent-Tiering offers. Additionally, it does not address the need for archived data management.
