Question
A global company runs a data lake application in the us-east-1 Region and the eu-west-1 Region in an active-passive configuration. Application data is stored locally in Amazon S3 buckets in each AWS Region. The bucket in us-east-1 is the primary active bucket that handles all writes. The company needs to ensure that the application has Regional fault tolerance. The company also needs the storage layer to provide a highly available active-active capability for reads across Regions. The storage layer must provide low latency access through a single global endpoint. Which solution will meet these requirements?
Options
- ACreate an Amazon CloudFront distribution in each Region. Set the S3 bucket within each Region
- BUse S3 Transfer Acceleration for cross-Region data transfers to the S3 buckets.
- CConfigure AWS Backup to replicate S3 buckets across Regions. Set up a disaster recovery
- DCreate an S3 Multi-Region Access Point. Configure cross-Region replication.

Explanation
Amazon S3 Multi-Region Access Points allow applications to access S3 buckets in multiple Regions through a single global endpoint. This provides active-active read access with automatic routing to the closest bucket for low latency. With cross-Region replication, writes in the primary Region are automatically copied to the secondary Region, providing fault tolerance. Option A (CloudFront) provides caching and distribution, but does not address write replication or active-active bucket access. Option B (Transfer Acceleration) optimizes uploads across distances but does not enable cross- Region fault tolerance. Option C (AWS Backup) is designed for backup/restore, not real-time multi-Region reads and Therefore, D is the correct solution for active-active read access and disaster recovery.
