SAA-C03 Question 239
Select 1A company is running a cloud-based application that requires storage for the following use cases: storing application logs, hosting a shared filesystem for multiple EC2 instances, and running a high-performance database. Which combination of AWS storage services best meets these requirements?
- A
Amazon S3 for storing logs, Amazon EFS for the shared filesystem, and Amazon EBS for the database
- B
Amazon S3 for storing logs, Amazon FSx for the shared filesystem, and Amazon EBS for the database
- C
Amazon S3 for storing logs, Amazon EFS for the shared filesystem, and Amazon RDS for the database
- D
Amazon S3 for storing logs, Amazon EFS for the shared filesystem, and Amazon Glacier for the database
Show answer and explanation
Correct answer: A
Explanation
Each storage type has specific use cases. Amazon S3 is suitable for storing logs as it provides durable and scalable object storage. Amazon EFS offers a shared file system that can be accessed by multiple EC2 instances. Amazon EBS provides block-level storage optimized for performance-intensive workloads, such as databases. This combination effectively addresses all the use cases described in the question.
- A. Correct.
Correct. Amazon S3 is optimal for storing logs due to its object storage capabilities, Amazon EFS provides a scalable shared filesystem for EC2 instances, and Amazon EBS is ideal for high-performance block storage required by databases.
- B. Incorrect.
Incorrect. While Amazon FSx could provide a shared filesystem, it is not the best fit for the given scenario, as Amazon EFS is specifically designed for Linux-based EC2 instances and auto-scales more effectively for this use case.
- C. Incorrect.
Incorrect. Amazon RDS is a managed database service, not a storage service. The question specifically asks about storage types, and RDS does not directly meet the storage requirement for databases.
- D. Incorrect.
Incorrect. Amazon Glacier is designed for archival storage and is not suitable for use cases requiring high performance, such as databases.
