CLF-C02 Question 220
Select 2A company wants to implement a storage solution for their application that requires low-latency access to frequently accessed data, while also being able to store less frequently accessed data cost-effectively. Which combination of AWS storage services would best meet their needs?
- A
Amazon S3 Standard and Amazon S3 Glacier
- B
Amazon S3 Intelligent-Tiering and Amazon S3 Glacier
- C
Amazon EBS and Amazon S3 Glacier
- D
Amazon EBS and Amazon EFS
- E
Amazon S3 Standard and Amazon EFS
Show answer and explanation
Correct answers: B, E
Explanation
The best solution for this scenario involves Amazon S3 Intelligent-Tiering and Amazon S3 Glacier. S3 Intelligent-Tiering is designed to automatically optimize storage costs by moving data between tiers based on access patterns, making it ideal for managing both frequently and infrequently accessed data. S3 Glacier complements this by providing a cost-effective option for long-term archival storage. Together, they meet the requirements for low-latency access to frequently accessed data and cost-effective storage for less frequently accessed data. Additionally, Amazon S3 Standard and Amazon EFS could be considered if the application requires both object and file storage functionality.
- A. Incorrect.
Amazon S3 Standard is ideal for frequently accessed data, and Amazon S3 Glacier is designed for long-term archival storage. However, this combination does not provide automatic cost optimization for less frequently accessed data.
- B. Correct.
Amazon S3 Intelligent-Tiering automatically moves data between access tiers based on usage patterns, optimizing costs for infrequently accessed data. Pairing it with Amazon S3 Glacier allows for cost-effective archival storage.
- C. Incorrect.
Amazon EBS is a block storage service for EC2 instances, and it is not designed for scalable object storage or archival storage use cases. Amazon S3 Glacier is suitable for archival, but EBS is not appropriate for frequent or infrequent access scenarios outside EC2 instances.
- D. Incorrect.
Amazon EBS is designed for block storage attached to EC2 instances, and Amazon EFS provides a scalable file storage solution for applications. This combination does not provide an object storage layer, nor does it optimize costs for less frequently accessed data.
- E. Correct.
Amazon S3 Standard provides low-latency and high-throughput object storage for frequently accessed data, while Amazon EFS offers scalable, low-latency file storage that can be shared across instances. This combination suits applications with both object and file storage needs.
