[All AWS Certified Solutions Architect - Professional Questions]

A solutions architect works for a government agency that has strict disaster recovery requirements.

The agency also is required to maintain the lowest possible operational overhead.
Which solution meets these requirements?

A. Configure a policy in Amazon Data Lifecycle Manager (Amazon DLM) to run once daily to copy the EBS snapshots to the additional Regions.
B. Use Amazon EventBridge (Amazon CloudWatch Events) to schedule an AWS Lambda function to copy the EBS snapshots to the additional Regions.
C. Set up AWS Backup to create the EBS snapshots. Configure Amazon S3 cross-Region replication to copy the EBS snapshots to the additional Regions.
D. Schedule Amazon EC2 Image Builder to run once daily to create an AMI and copy the AMI to the additional Regions.

Answer is A. Amazon DLM features: Automated snapshot and AMI creation: Create a policy that automates the creation, retention, and deletion of EBS snapshots and EBS-backed AMIs. Fast snapshot restore integration: Automate the creation of snapshots that are enabled for fast snapshot restore. Fast snapshot restore enables you to restore volumes that are fully initialized at creation and instantly deliver all of their provisioned performance. Built-in cross-Region copy: Automatically copy snapshots that are created by a lifecycle policy to up to three AWS Regions. Automated cross-account snapshot copy: Use cross-account sharing in conjunction with a cross-account copy event policy to automatically share and copy snapshots created by a policy across accounts.

I would choose C over A. AWS Backup has MUCH less overhead in both configuration and monitoring of backup jobs for EBS snapshots (and is the newer of the two services).

Just re-read answer C and although I think AWS Backup (can do EBS backups) itself has less operational overhead than DLM, you do not have access to the S3 buckets to be able to configure cross-region replication - you would configure that cross-region replication within AWS Backup itself. So answer C is not technically feasible. It has to be A.
