DOP-C02 Question #425: Real Exam Question with Answer & Explanation

Question

A company uses a CI/CD pipeline to deploy its workload in the ap-southeast-2 Region. The company receives images through a Network Load Balancer (NLB) and processes the images in AWS Fargate tasks on an Amazon Elastic Container Service (Amazon ECS) cluster. An Amazon Elastic Container Registry (Amazon ECR) repository stores the images as Docker images. The company uses Amazon Route 53 to configure DNS. The company saves the images in an Amazon S3 bucket and saves the metadata from the images in an Amazon DynamoDB table. The company wants to expand the workload to a second Region. A DevOps engineer needs to build a highly available and resilient design to expand the workload to the eu-west-2 Region. Which combination of steps will meet these requirements with the FEWEST configuration changes? (Choose three.)

Options

• AConfigure ECR replication to eu-west-2 on the repository. Configure an NLB in eu-west-2 that
• BConfigure the DynamoDB table as a global table with a replica in eu-west-2. Configure the
• CConfigure the DynamoDB table as a global table with a replica in eu-west-2. Configure the
• DConfigure a new S3 bucket in eu-west-2. Configure data replication between the S3 bucket in ap-
• EConfigure an S3 Multi-Region Access Point for the S3 bucket in ap-southeast-2 and a new S3
• FConfigure the CI/CD pipeline to deploy ECR images to both Regions. Configure an NLB in eu-

Explanation

(A) Use ECR replication to keep images synchronized between Regions, minimizing CI/CD pipeline changes. (C) DynamoDB global tables allow multi-Region replication and provide local read/write access, so tasks should interact with the DynamoDB replica in their Region. (D) Use S3 cross-Region replication or separate buckets with replication; tasks access the bucket in the same Region for latency and data sovereignty. (B) Using DynamoDB global table but pointing tasks to only one Region reduces resilience. (E) S3 Multi-Region Access Points are newer but add complexity and are not required for minimal (F) Managing CI/CD pipeline for multiple Regions and failover routing adds complexity beyond minimal changes.
