SAP-C02 Question 633
Single answerYour company is running a large-scale application that processes and analyzes vast amounts of unstructured data. The application requires a shared file system that can scale on demand, supports concurrent access from hundreds of EC2 instances, and provides low-latency access to data. Additionally, the solution must integrate seamlessly with AWS services and be managed without the need for provisioning or maintaining infrastructure. Which AWS storage service should you choose?
- A
Amazon Elastic File System (Amazon EFS)
- B
Amazon S3
- C
Amazon FSx for Windows File Server
- D
Amazon Elastic Block Store (Amazon EBS)
Show answer and explanation
Correct answer: A
Explanation
Amazon Elastic File System (Amazon EFS) is the optimal solution for this scenario because it provides a fully managed, scalable, and shared file system that supports concurrent access from multiple EC2 instances. It is designed to handle use cases requiring elastic scalability and low-latency access, meeting all the requirements outlined in the scenario. Other options like Amazon S3, FSx for Windows File Server, and EBS do not meet the specific needs for a shared, scalable file system.
- A. Correct.
Amazon Elastic File System (Amazon EFS) is a fully managed, scalable file storage service that provides low-latency access to data, supports concurrent access from multiple EC2 instances, and requires no infrastructure management. It is ideal for applications that need shared file systems with elastic scalability.
- B. Incorrect.
Amazon S3 is an object storage service, not a file system. While it offers scalability and durability, it does not provide the low-latency access of a shared file system or support for traditional file system operations.
- C. Incorrect.
Amazon FSx for Windows File Server is a managed file storage service specifically designed for Windows-based applications. While it supports shared access, it is not ideal for Linux-based workloads or applications requiring elastic scalability.
- D. Incorrect.
Amazon Elastic Block Store (Amazon EBS) provides block-level storage for individual EC2 instances. It is not a shared file system and does not support concurrent access from multiple instances.
