  • Topic 1 Question 85

    An application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). A DevOps engineer is using AWS CodeDeploy to release a new version. The deployment fails during the AllowTraffic lifecycle event, but a cause for the failure is not indicated in the deployment logs.

    What would cause this?

    • The appspec.yml file contains an invalid script that runs in the AllowTraffic lifecycle hook.

    • The user who initiated the deployment does not have the necessary permissions to interact with the ALB.

    • The health checks specified for the ALB target group are misconfigured.

    • The CodeDeploy agent was not installed in the EC2 instances that are part of the ALB target group.
