CLF-C02 Question 233
Single answerA company is building a new application that requires a shared file storage solution for multiple Amazon EC2 instances. The solution must provide scalable storage and support access from multiple instances concurrently. Which AWS service is the most appropriate for this use case?
- A
Amazon Elastic File System (Amazon EFS)
- B
Amazon S3
- C
Amazon FSx for Windows File Server
- D
Amazon RDS
Show answer and explanation
Correct answer: A
Explanation
Amazon Elastic File System (Amazon EFS) is the best choice for this scenario because it is a fully managed service that provides scalable, elastic file storage designed for concurrent access by multiple Amazon EC2 instances. It is ideal for use cases requiring shared file systems with high availability and scalability.
- A. Correct.
Amazon Elastic File System (Amazon EFS) is a fully managed, scalable file storage service designed to be shared across multiple Amazon EC2 instances. It supports concurrent access and is ideal for workloads requiring shared file systems.
- B. Incorrect.
Amazon S3 is an object storage service and does not provide the shared file system capabilities required for this use case. It is optimized for storing and retrieving large amounts of unstructured data, rather than file system-based workloads.
- C. Incorrect.
Amazon FSx for Windows File Server is a managed file storage service for Windows-based applications. While it can support shared access, it is primarily optimized for Windows environments, making it less appropriate for general Linux-based shared storage needs.
- D. Incorrect.
Amazon RDS is a relational database service and is not relevant to file storage use cases. It is designed for structured data storage and database management, which does not meet the requirements of this scenario.
