Question 28 (Topic 1)

A company operates a globally deployed product out of multiple AWS Regions. The company's DevOps team needs to use Amazon API Gateway to deploy an API to support the product. The API must be deployed redundantly. The deployment must provide independent availability from each company location. The deployment also must respond to a custom domain URL and must optimize performance for the API user requests. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Deploy an API Gateway edge-optimized API endpoint in the us-east-1 Region. Create an API Gateway custom domain for the API. Create an Amazon Route 53 record set with a geoproximity routing policy for the API's custom domain. Increase the geographic bias to the maximum allowed value.
  • ○ Deploy an API Gateway regional API endpoint in the us-east-1 Region. Integrate the API Gateway API with a public Application Load Balancer (ALB). Create an AWS Global Accelerator standard accelerator. Associate the endpoint with the ALCreate an Amazon Route 53 alias record set that points the custom domain name to the DNS name that is assigned to the accelerator.
  • ○ Deploy an API Gateway regional API endpoint in every AWS Region where the company's product is deployed. Create an API Gateway custom domain in each Region for the deployed API Gateway API. Create an Amazon Route 53 record set that has a latency routing policy for every deployed API Gateway custom domain.
  • ○ Deploy an API Gateway edge-optimized API endpoint in the us-east-1 Region. Create an Amazon CloudFront distribution. Configure the CloudFront distribution with an alternate domain name. Specify the API Gateway Invoke URL as the origin domain. Create an Amazon Route 53 alias record set with a simple routing policy. Point the routing policy to the CloudFront distribution domain name.
Question 29 (Topic 1)

A DevOps engineer uses AWS CodeBuild to frequently produce software packages. The CodeBuild project builds large Docker images that the DevOps engineer can use across multiple builds. The DevOps engineer wants to improve build performance and minimize costs. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Store the Docker images in an Amazon Elastic Container Registry (Amazon ECR) repository. Implement a local Docker layer cache for CodeBuild.
  • ○ Cache the Docker images in an Amazon S3 bucket that is available across multiple build hosts. Expire the cache by using an S3 Lifecycle policy.
  • ○ Store the Docker images in an Amazon Elastic Container Registry (Amazon ECR) repository. Modify the CodeBuild project runtime configuration to always use the most recent image version.
  • ○ Create custom AMIs that contain the cached Docker images. In the CodeBuild build, launch Amazon EC2 instances from the custom AMIs.
Question 30 (Topic 1)

A DevOps engineer needs to configure a blue/green deployment for an existing three-tier application. The application runs on Amazon EC2 instances and uses an Amazon RDS database. The EC2 instances run behind an Application Load Balancer (ALB) and are in an Auto Scaling group. The DevOps engineer has created launch templates, Auto Scaling groups, and ALB target groups for the blue environment and the green environment. Each target group specifies which application version, blue or green, will be loaded on the EC2 instances. An Amazon Route 53 record for www.example.com points to the ALB. The deployment must shift traffic all at once from the blue environment to the green environment. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Starta rolling restart of the Auto Scaling group for the green environment to deploy the new application version to the green environment's EC2 instances. When the rolling restart is complete, use an AWS CLI command to update the ALB to send traffic to the green environment's target group.
  • ○ Use an AWS CLI command to update the ALB to send traffic to the green environments target group. Start a rolling restart of the Auto Scaling group for the green environment to deploy the new application version to the green environment's EC2 instances.
  • ○ Update the launch template to deploy the green environment's application version to the blue environment's EC2 instances. Do not change the target groups or the Auto Scaling groups in either environment. Perform a rolling restart of the blue environments EC2 instances.
  • ○ Starta rolling restart of the Auto Scaling group for the green environment to deploy the new application version to the green environment's EC2 instances. When the rolling restart is complete, update Route 53 to point to the green environment's endpoint on the ALB.
