Questions 37

A company has an application that runs on Amazon EC2 instances. The company uses an AWS CodePipeline pipeline to deploy the application into multiple AWS Regions. The pipeline is configured with a stage for each Region. Each stage contains an AWS CloudFormation action for each Region.

When the pipeline deploys the application to a Region, the company wants to confirm that the application is in a healthy state before the pipeline moves on to the next Region. Amazon Route 53 record sets are configured for the application in each Region.

Remove the CloudFormation actions from the pipeline. Create a CodeDeploy action in the pipeline stage for each Region.

C.

Create a new pipeline stage for each Region where the application is deployed. Configure a CloudWatch alarm action for the new stage to check the state of the CloudWatch alarm and to exit with an error if the alarm is in the ALARM state.

D.
