AWS Certified Cloud Practitioner — Question 430

Which AWS service allows for file sharing between multiple Amazon EC2 instances?

Answer options

• A. AWS Direct Connect
• B. AWS Snowball Edge
• C. AWS Backup
• D. Amazon Elastic File System (Amazon EFS)

Correct answer: D

Explanation

Amazon Elastic File System (Amazon EFS) is designed to provide serverless, fully managed file storage that can be mounted simultaneously by multiple Amazon EC2 instances. AWS Direct Connect is a networking service for dedicated connections, AWS Snowball Edge is physical hardware for data migration, and AWS Backup is used for centralized backup management, making none of them suitable for active file sharing.
