Question
A company asks a SysOps administrator to provision an additional environment for an application in four additional AWS Regions. The application is running on more than 100 Amazon EC2 instances in the us-east-1 Region, using fully configured Amazon Machine Images (AMIs). The company has an AWS CloudFormation template to deploy resources in us-east-1. What should the SysOps administrator do to provision the application in the MOST operationally efficient manner?
Options
- ACopy the AMI to each Region by using the aws ec2 copy-image command. Update the
- BCreate a snapshot of the running instance. Copy the snapshot to the other Regions. Create an
- CRun the existing CloudFormation template in each additional Region based on the success of the
- DUpdate the CloudFormation template to include the additional Regions in the Auto Scaling group.

Explanation
Copy the AMI to each target Region using copy-image and update the CloudFormation template to reference the correct AMI IDs per Region (commonly via Mappings or parameters). AMIs are regional resources, so an AMI built in us-east-1 cannot be launched directly in other Regions without copying. The copy-image operation is the standard, supported method to replicate an AMI across Regions while preserving the image configuration and backing snapshots in the destination Region. Once AMIs exist in each Region, CloudFormation can be executed in each Region using the same template logic. Adding mappings for AMI IDs keeps the deployment consistent and repeatable, aligning with Infrastructure as Code practices and minimizing manual steps.
