Question 10

You are building an AWS CloudFormation template for a multi-tier web application. The user data of your Linux web server resource contains a complex script that can take a long time to run. Which techniques could you use to ensure that these servers are fully configured and running before attaching them to the load balancer? (Choose two.)

Select all that apply, then click Submit answer.

  • ○

    Launch your Linux servers from a nested stack that is called from within the load balancer resource in your AWS CloudFormation template.
  • ○

    Add an AWS CloudFormation Wait Condition that depends on the web server resource. When the UserData script finishes on the web servers, use curl to send a signal the Wait Condition at http://169.254.169.254/waithandle/.
  • ○

    Add an AWS CloudFormation wait Condition that depends on the web server resource. When the UserData script finishes on the web servers, use curl to signal to the Wait Condition pre-signed URL that they are ready.
  • ○

    In your AWS CloudFormation template, position the load balancer resource JSON block directly below your Linux server resource.
  • ○

    Add an AWS CloudFormation Wait Condition that depends on the web server resource. When the UserData script finishes on the web servers, use the command "cfn-signal" to signal that they are ready.

Select an option, then click Submit answer.

  • ○

    Set up an Amazon ECS environment. Use AWS CodePipeline to create a pipeline that is triggered on a commit to the GitHub repository. Use AWS CodeBuild to create the container images and AWS CodeDeploy to publish the container image to the ECS environment.
  • ○

    Use AWS CodePipeline that triggers on a commit from the GitHub repository, build the container images with AWS CodeBuild, and publish the container images to Amazon ECR. In the final stage, use AWS CloudFormation to create an Amazon ECS environment that gets the container images from the ECR repository.
  • ○

    Create a Kubernetes Cluster on Amazon EC2. Use AWS CodePipeline to create a pipeline that is triggered when the code is committed to the repository. Create the container images with a Jenkins server on EC2 and store them in the Docker Hub. Use AWS Lambda from the pipeline to trigger the deployment to the Kubernetes Cluster.
  • ○

    Set up an Amazon ECS environment. Use AWS CodePipeline to create a pipeline that is triggered on a commit to the GitHub repository. Use AWS CodeBuild to create the container and store it in the Docker Hub. Use an AWS Lambda function to trigger a deployment and pull the new container image from the Docker Hub.
