Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Backup
AWS Backup is the correct answer because it provides a centralized backup service that can copy EBS snapshots across AWS Regions as part of backup plans. Amazon Data Lifecycle Manager (DLM) can automate snapshot creation and retention, but its cross-Region copy capabilities are limited compared to AWS Backup's comprehensive backup policies. Option C, S3 Cross-Region Replication, applies to S3 objects, not EBS snapshots. Option D, CloudFormation StackSets, is used for infrastructure provisioning across accounts/regions, not for backup.
