SAP-C02 Question 666
Single answerA company is migrating its on-premises data to AWS. They require a shared file system for their application servers running on Amazon EC2 instances. The file system must support the ability to scale automatically based on the workload, provide low-latency access, and seamlessly integrate with AWS Identity and Access Management (IAM) for access control. Which AWS storage service should the company use to meet these requirements?
- A
Amazon EFS
- B
Amazon S3
- C
Amazon FSx for Windows File Server
- D
Amazon Glacier
Show answer and explanation
Correct answer: A
Explanation
The correct answer is Amazon EFS because it is a managed file system designed for use with Amazon EC2 instances. It offers key features such as scalability, low-latency access, and IAM integration, which align perfectly with the described requirements. Other options like Amazon S3 and Amazon Glacier are not file systems, and Amazon FSx for Windows File Server is tailored for Windows-specific use cases.
- A. Correct.
Amazon EFS (Elastic File System) is a fully managed, scalable file storage service for use with Amazon EC2. It supports automatic scaling, low-latency access, and integration with IAM for access control, making it the best choice for this scenario.
- B. Incorrect.
Amazon S3 is an object storage service that is highly scalable and durable but does not provide the shared file system functionality required in this scenario.
- C. Incorrect.
Amazon FSx for Windows File Server is a fully managed Windows-based file system. While it provides a shared file system, it is specifically optimized for Windows workloads and not the best fit for the general use case described here.
- D. Incorrect.
Amazon Glacier is an archival storage service designed for long-term data retention and infrequent access. It does not meet the requirements for a low-latency shared file system.
