AWS Certified Solutions Architect – Associate (SAA-C02) — Question 522

A company hosts its enterprise content management platform in one AWS Region but needs to operate the platform across multiple Regions. The company has an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that runs its microservices. The EKS cluster stores and retrieves objects from Amazon S3. The EKS cluster also stores and retrieves metadata from Amazon DynamoDB.
Which combination of steps should a solutions architect take to deploy the platform across multiple Regions? (Choose two.)

Answer options

• A. Replicate the EKS cluster with cross-Region replication.
• B. Use Amazon API Gateway to create a global endpoint to the EKS cluster.
• C. Use AWS Global Accelerator endpoints to distribute the traffic to multiple Regions.
• D. Use Amazon S3 access points to give access to the objects across multiple Regions. Configure DynamoDB Accelerator (DAX). Connect DAX to the relevant tables.
• E. Deploy an EKS cluster and an S3 bucket in another Region. Configure cross-Region replication on both S3 buckets. Turn on global tables for DynamoDB.

Correct answer: C, E

Explanation

To deploy the platform across multiple Regions, you must replicate the infrastructure and data layers: Option E achieves this by setting up the EKS and S3 resources in the new Region, using S3 Cross-Region Replication for object sync, and enabling DynamoDB global tables for multi-region metadata replication. Option C is correct because AWS Global Accelerator provides a single entry point to route user traffic to the closest regional endpoint, ensuring high availability and low latency. Other options are incorrect because EKS does not support native cross-region replication, API Gateway is regional, and DAX is a caching service that does not replicate data across regions.
