A company needs a scalable image repository that grows automatically, supports versioning, and keeps multiple immediately accessible copies in different AWS Regions. Which storage option meets these requirements?

Amazon S3 with Cross-Region Replication (CRR) is the correct choice because it inherently offers scalability, versioning, and the ability to maintain multiple, immediately accessible copies across different AWS Regions. S3 buckets automatically scale to accommodate virtually unlimited data, and S3 Versioning can be enabled to preserve every version of an object. CRR asynchronously replicates objects to a destination bucket in a different AWS Region, ensuring high availability and disaster recovery with immediate accessibility. Amazon EBS volumes are block storage attached to EC2 instances and are not designed as a scalable, standalone image repository across regions for direct access. Snapshots require restoration to become accessible. Amazon EFS is a scalable file system but is regional and does not inherently provide cross-region replication for immediate accessibility without additional setup. AWS Storage Gateway Volume Gateway provides on-premises applications with cloud-backed storage but is not a native cloud-based, scalable image repository with built-in cross-region replication for direct access.
