CLF-C02 Question 232
Single answerA company is migrating its on-premises file storage system to AWS. They require a solution that supports shared file access for Linux-based workloads with automatic scaling to handle unpredictable storage demands. Which AWS service should they use?
- A
Amazon S3
- B
Amazon Elastic File System (Amazon EFS)
- C
Amazon FSx for Windows File Server
- D
Amazon Glacier
Show answer and explanation
Correct answer: B
Explanation
Amazon Elastic File System (Amazon EFS) is the best choice for this use case because it provides shared, scalable file storage designed for Linux-based workloads. It automatically scales to meet unpredictable storage demands, making it a suitable solution for the company's requirements. Other services like Amazon S3, FSx for Windows File Server, and Glacier do not meet the specific needs of shared file access for Linux-based workloads.
- A. Incorrect.
Amazon S3 is an object storage service, not a file storage service. It is not designed to provide shared file access for workloads such as Linux-based applications.
- B. Correct.
Amazon Elastic File System (Amazon EFS) is a fully managed file storage service that provides shared file access and is specifically designed for Linux-based workloads with automatic scaling, making it the ideal choice for this scenario.
- C. Incorrect.
Amazon FSx for Windows File Server is designed for Windows-based workloads, not Linux-based workloads, making it unsuitable for this scenario.
- D. Incorrect.
Amazon Glacier is an archival storage service for infrequent access and is not suitable for shared file access or Linux-based workloads.
