SAP-C02 Question 542
Single answerYour organization is migrating a legacy on-premises application to AWS. The application relies on a shared file system for storing user data and application logs. During the migration process, the team wants to modernize the solution to improve scalability and reduce management overhead while ensuring data consistency and high availability across multiple Availability Zones. Which AWS service should you recommend?
- A
Amazon Elastic File System (EFS)
- B
Amazon FSx for Windows File Server
- C
Amazon S3 with S3 Transfer Acceleration
- D
Amazon Elastic Block Store (EBS)
Show answer and explanation
Correct answer: A
Explanation
The correct answer is Amazon Elastic File System (EFS) because it is a modern solution designed for shared file storage across multiple instances and Availability Zones. It eliminates the need for managing traditional file systems and provides scalability and high availability, aligning with the team's goal of modernizing the application during migration.
- A. Correct.
Amazon Elastic File System (EFS) is a fully managed, scalable, and highly available file system that supports multiple Availability Zones and is ideal for applications requiring shared storage for multiple instances. It provides the scalability and minimal management overhead your team is looking for.
- B. Incorrect.
Amazon FSx for Windows File Server is designed for Windows-based applications and workloads requiring SMB file system support. While it provides shared file storage, it is not the best fit for modernizing this specific application unless the workload has Windows-specific requirements.
- C. Incorrect.
Amazon S3 with S3 Transfer Acceleration is a highly durable object storage service, not a file system. It is not a suitable replacement for a shared file system used by the application.
- D. Incorrect.
Amazon Elastic Block Store (EBS) provides block storage for individual EC2 instances. It does not support sharing data across multiple instances or Availability Zones, making it unsuitable for this use case.
