AWS Certified SysOps Administrator – Associate — Question 263

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 C2 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?

Answer options

• A. Copy the AMI to each Region by using the aws ec2 copy-image command. Update the CloudFormation template to include mappings for the copied AMIs.
• B. Create a snapshot of the running instance. Copy the snapshot to the other Regions. Create an AMI from the snapshots. Update the CloudFormation template for each Region to use the new AMI.
• C. Run the existing CloudFormation template in each additional Region based on the success of the template that is used currently in us-east-1.
• D. Update the CloudF ormation template to include the additional Regions in the Auto Scaling group. Update the existing stack in us-east-1.

Correct answer: A

Explanation

The correct answer is A because copying the AMIs directly to the required Regions allows for quick and efficient deployment without needing to create new snapshots or modify the existing instances. Option B is less efficient as it involves additional steps like creating snapshots and AMIs. Option C does not address the need for AMIs in the new Regions and simply replicates the existing setup without optimizing the process. Option D does not address the requirement of having the AMIs available in the new Regions.
