AWS Certified Solutions Architect – Professional — Question 1009

A solutions architect works for a government agency that has strict disaster recovery requirements. All Amazon Elastic Block Store (Amazon EBS) snapshots are required to be saved in at least two additional AWS Regions. The agency also is required to maintain the lowest possible operational overhead.
Which solution meets these requirements?

Answer options

• 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.

Correct answer: A

Explanation

Amazon Data Lifecycle Manager (Amazon DLM) provides native, policy-based automation to manage and copy EBS snapshots to multiple target AWS Regions, meeting the requirement with the lowest operational overhead. Option B is less desirable because writing and maintaining custom AWS Lambda code increases operational complexity. Option C is incorrect because Amazon S3 cross-Region replication does not apply directly to EBS snapshots, and Option D is incorrect because managing AMIs via Amazon EC2 Image Builder is overly complex for simple EBS snapshot replication.
