Which combination of steps should a solutions architect take to deploy the platform across multiple Regions?

Explanations:

AWS does not support cross-Region replication of EKS clusters. Each EKS cluster is specific to a single Region, so replicating the entire EKS cluster is not a valid step. Instead, a new EKS cluster must be deployed in each Region where the platform will operate.

While Amazon API Gateway can create endpoints for services running in a specific Region, it does not create a global endpoint for an EKS cluster across multiple Regions. It typically connects to a single Region’s resources. For multi-Region access, a different architecture would be required.

AWS Global Accelerator provides a way to improve the availability and performance of applications with users across the globe. By using it, traffic can be directed to the optimal Region based on latency, improving the response time and user experience for the services deployed in multiple Regions.

While S3 Access Points can facilitate access to S3 buckets across Regions, this option does not address the need for cross-Region access for DynamoDB. DAX, while providing caching capabilities for DynamoDB, does not automatically enable cross-Region access for the primary data.

Deploying an EKS cluster and S3 bucket in another Region is necessary for multi-Region operations. Configuring cross-Region replication on S3 buckets ensures that data is available in both Regions. Enabling DynamoDB global tables allows for the metadata to be replicated across Regions, providing a consistent view of the data.
