CLF-C02 Question 231
Single answerA company needs a scalable file system to support its Linux-based web applications. The solution must allow multiple EC2 instances to concurrently access the same file system with low latency. Which AWS service should the company use?
- A
Amazon Elastic File System (Amazon EFS)
- B
Amazon S3
- C
Amazon FSx for Windows File Server
- D
Amazon Glacier
Show answer and explanation
Correct answer: A
Explanation
Amazon EFS is the best choice for Linux-based applications requiring a scalable file system that supports concurrent access by multiple EC2 instances. The other options either do not provide file system functionality or are designed for different use cases.
- A. Correct.
Amazon EFS is a fully managed, scalable file storage system designed to support Linux-based workloads. It allows multiple EC2 instances to access the same file system concurrently, making it the correct choice for this scenario.
- B. Incorrect.
Amazon S3 is an object storage service, not a file system. It is suited for storing and retrieving large amounts of unstructured data, but it does not provide the file system capabilities required in this scenario.
- C. Incorrect.
Amazon FSx for Windows File Server is designed for Windows-based workloads and would not be suitable for Linux-based applications as described in the scenario.
- D. Incorrect.
Amazon Glacier is a long-term, low-cost archival storage solution, not a file system. It is not suitable for scenarios requiring low-latency, concurrent access.
