A government agency requires all Amazon EBS snapshots to be stored in at least two additional AWS Regions and wants to minimize operational overhead. Which solution satisfies these requirements?

Amazon Data Lifecycle Manager (DLM) is the most suitable solution because it automates the creation, retention, and deletion of EBS snapshots, and crucially, it supports cross-Region snapshot copy as a built-in feature. This directly addresses the requirement for storing snapshots in additional AWS Regions with minimal operational overhead, as it's a fully managed service. Using Amazon EventBridge with a Lambda function would require custom code development and maintenance, increasing operational overhead. AWS Backup is excellent for creating snapshots, but EBS snapshots are stored in EBS, not S3, so S3 Cross-Region Replication is irrelevant. EC2 Image Builder creates AMIs, not raw EBS snapshots, and copying AMIs is not the same as copying EBS snapshots for disaster recovery purposes.
