Answer: Amazon Elastic Block Store (Amazon EBS)

## Explanation Amazon Elastic Block Store (Amazon EBS) is the correct choice because: - **EBS volumes can be attached to EC2 instances** and provide persistent block storage - **EBS snapshots can be shared across Availability Zones** and regions - **Multiple EC2 instances can access the same data** through EBS snapshots or by creating volumes from snapshots in different Availability Zones - **EBS provides durable storage** that persists independently from the life of an EC2 instance ### Why other options are incorrect: - **AWS Direct Connect**: This is for establishing dedicated network connections from on-premises to AWS, not for sharing data between EC2 instances - **AWS Database Migration Service (AWS DMS)**: This is for migrating databases between sources, not for general data sharing between EC2 instances - **Amazon FSx for Windows File Server**: This is specifically for Windows file shares and is not the most general-purpose solution for reading data from multiple EC2 instances across Availability Zones EBS is the most appropriate service for this use case as it provides block-level storage that can be accessed by EC2 instances and shared across Availability Zones through snapshots.
