SAA-C03 Question 368
Select 2A company is planning to deploy a new analytics application on AWS. The application requires low-latency access to data and will process large datasets of up to 10 TB daily. The processed data must be stored for long-term archiving at the lowest possible cost, but it should remain accessible within minutes if needed. Which combination of AWS services should you recommend to meet these requirements?
- A
Amazon S3 Standard for active data processing and Amazon S3 Glacier for long-term storage
- B
Amazon EBS Provisioned IOPS SSD (io2) volumes for data processing and Amazon S3 Glacier Deep Archive for long-term storage
- C
Amazon EFS for active data processing and Amazon S3 Intelligent-Tiering for long-term storage
- D
Amazon S3 Standard for active data processing and Amazon S3 Intelligent-Tiering for long-term storage
- E
Amazon EFS for active data processing and Amazon S3 Glacier for long-term storage
Show answer and explanation
Correct answers: C, D
Explanation
The combination of Amazon EFS and S3 Intelligent-Tiering (Option 3) or S3 Standard and S3 Intelligent-Tiering (Option 4) is the best solution for this scenario. Amazon EFS provides low-latency access for active data processing, and Amazon S3 Intelligent-Tiering ensures cost-optimized long-term storage with fast retrieval capabilities. These options meet the performance, storage, and cost requirements described in the scenario.
- A. Incorrect.
This option is not ideal because Amazon S3 Standard is suitable for active data but S3 Glacier is not designed for fast retrieval, which is required in this scenario.
- B. Incorrect.
Amazon EBS io2 volumes offer high performance for active data processing, but they are cost-prohibitive for processing large datasets (10 TB daily). S3 Glacier Deep Archive is the most cost-effective storage option but is not suitable for retrieval within minutes.
- C. Correct.
Amazon EFS provides low-latency access suitable for active data processing, and Amazon S3 Intelligent-Tiering is optimal for long-term storage with automatic cost optimization and fast retrieval capabilities.
- D. Correct.
Amazon S3 Standard is suitable for active data processing with low latency, and Amazon S3 Intelligent-Tiering provides cost-effective long-term storage with fast retrieval, making this combination a good fit for the scenario.
- E. Incorrect.
Amazon EFS is suitable for low-latency active data processing, but Amazon S3 Glacier is not ideal for long-term storage in this scenario due to delayed retrieval times.
