Click on the arrows to vote for the correct answer
A. B. C. D.Answer: A.
Option A is CORRECT.
Amazon EFS is a regional service storing data within and across multiple Availability Zones (AZs) for high availability and durability.
You can access your file systems across AZs and regions.
You can also share files between thousands of Amazon EC2 instances and on-premises servers via AWS Direct Connect or AWS VPN.
Option B is INCORRECT.
Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading scalability, data availability, security, and performance.
Option C is INCORRECT.
Amazon Elastic Block Store (Amazon EBS) provides persistent block storage volumes for Amazon EC2 instances in the AWS Cloud.
Option D is INCORRECT.
Amazon FSx for Windows File Server provides a fully managed native Microsoft Windows file system so you can easily move your Windows-based applications that require file storage to AWS.
Reference:
https://docs.aws.amazon.com/whitepapers/latest/aws-overview/storage-services.htmlThe AWS service that would satisfy the requirement of a filesystem that can be simultaneously mounted from different instances of EC2 is Amazon Elastic File System (EFS), option A.
Amazon EFS is a scalable and fully managed cloud-based file storage service that provides a simple and scalable file system for use with Amazon EC2 instances. With EFS, multiple EC2 instances can access the same file system concurrently, providing a shared file storage solution that can be used for a variety of use cases.
Option B, Amazon S3 (Simple Storage Service), is a highly scalable object storage service that is designed for storing and retrieving large amounts of data, but it is not a file system and is not designed for simultaneous access from multiple EC2 instances.
Option C, Amazon Elastic Block Store (EBS), provides block-level storage volumes that can be attached to EC2 instances, but it is not a file system and cannot be simultaneously mounted from multiple EC2 instances.
Option D, Amazon FSx for Windows File Server, is a fully managed Windows file system that is designed to provide shared file storage for Windows-based applications and workloads, but it is not designed for simultaneous access from multiple EC2 instances.
Therefore, the correct answer is A, Amazon Elastic File System (EFS).
