SAP-C02 Question 636
Single answerA company is running a critical application that requires a shared file system to store logs and temporary data. The application is deployed across multiple Availability Zones (AZs) within a single AWS Region. The solution needs to provide low latency access, high durability, and scalability while minimizing operational overhead. Which storage solution should you recommend?
- A
Amazon Elastic File System (Amazon EFS)
- B
Amazon S3 with Transfer Acceleration
- C
Amazon FSx for Windows File Server
- D
Amazon Elastic Block Store (Amazon EBS) with snapshots
Show answer and explanation
Correct answer: A
Explanation
Amazon EFS is the best solution for this scenario because it is a fully managed, scalable file system that can be accessed concurrently from multiple instances across AZs. It offers low latency and high durability, making it ideal for applications that require shared storage with minimal operational overhead. Other options, like Amazon S3 or Amazon EBS, do not meet the requirements for a shared file system with low latency and high scalability.
- A. Correct.
Amazon EFS is a fully managed, scalable, and highly available file storage service designed for use across multiple AZs. It supports shared access for multiple instances and is ideal for applications requiring shared file systems.
- B. Incorrect.
Amazon S3 with Transfer Acceleration is optimized for object storage and high-speed uploads, but it is not suitable for use cases requiring a shared file system with low latency access.
- C. Incorrect.
Amazon FSx for Windows File Server is designed for Windows-based applications and provides a shared file system, but it is not optimal for cross-AZ availability without additional configuration.
- D. Incorrect.
Amazon EBS is a block storage service meant for single instance usage. Snapshots provide data durability but do not allow for shared file system access or scalability across multiple AZs.
