Topic 1 Question 283
A company has an application that runs in a single AWS Region. The application runs on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster and connects to an Amazon Aurora MySQL cluster. The application is built in an AWS CodeBuild project. The container images are published to Amazon Elastic Container Registry (Amazon ECR).

The company needs to replicate the state of the application for the container images and the database to a second Region.

Which solution will meet these requirements in the MOST operationally efficient way?
- Turn on Amazon S3 Cross-Region Replication (CRR) on the bucket that holds the ECR container images. Deploy the application to an EKS cluster in the second Region by referencing the new S3 bucket object URL for the container image in a Kubernetes deployment file. Configure a cross-Region Aurora Replica in the second Region. Configure the new application deployment to use the endpoints for the cross-Region Aurora Replica.
- Create an Amazon EventBridge rule that reacts to image pushes to the ECR repository. Configure the EventBridge rule to invoke an AWS Lambda function to replicate the image to a new ECR repository in the second Region. Deploy the application to an EKS cluster in the second Region by referencing the new ECR repository in a Kubernetes deployment file. Configure a cross-Region Aurora Replica in the second Region. Configure the new application deployment to use the endpoints for the cross-Region Aurora Replica.
- Turn on Cross-Region Replication to replicate the ECR repository to the second Region. Deploy the application to an EKS cluster in the second Region by referencing the new ECR repository in a Kubernetes deployment file. Configure an Aurora global database with clusters in the initial Region and the second Region. Configure the new application deployment to use the endpoints for the second Region's cluster in the Aurora global database.
- Configure the CodeBuild project to also push the container image to an ECR repository in the second Region. Deploy the application to an EKS cluster in the second Region by referencing the new ECR repository in a Kubernetes deployment file. Configure an Aurora MySQL cluster in the second Region as the target for binary log replication from the Aurora MySQL cluster in the initial Region. Configure the new application deployment to use the endpoints for the second Region's cluster.

- 正解だと思う選択肢: C
  Why this is the most operationally efficient:
  
  • Minimal Management Overhead: AWS manages the replication for both the ECR images and the Aurora database. There is no need to configure or maintain additional Lambda functions or EventBridge rules. • Scalability: Aurora global databases and ECR replication are designed for production-grade systems and can scale to meet large workloads. • Reliability: The solution leverages AWS-native features, reducing the chance of errors or operational disruptions.
