Question 353

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?

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.

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.

Run the existing CloudFormation template in each additional Region based on the success of the template that is used currently in us-east-1.

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

The most operationally efficient manner to provision the application in additional AWS Regions is to copy the existing AMI to each target Region. This can be achieved by using the aws ec2 copy-image command, which allows the administrator to replicate the fully configured AMI to the desired Regions without recreating it from scratch or taking snapshots of running instances. After copying the AMI, the CloudFormation template should be updated to include mappings for the copied AMIs. This approach leverages the existing fully configured AMIs and ensures consistency across different Regions, facilitating the deployment process.

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.

Christina666Option: A

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. This option involves copying the AMI from the us-east-1 Region to the additional Regions using the aws ec2 copy-image command. Once the AMI is available in each of the target Regions, the CloudFormation template can be updated to include mappings for the copied AMIs in each Region. This allows you to use the fully configured AMI in each Region without needing to recreate it from scratch or take snapshots of running instances.

Yes, A makes sense.

kevino81Option: A

A it's correct

DeaconStJohnOption: A

I think mapping is the key word here

is running on > 100 EC2 instances of us-east-1 . --> Add four additional Regions --> Copy API to each Region.
