A company is using a single AWS Region (or its ecommerce website. The website includes a web application that runs on several Amazon EC2 instances behind an Application Load Balancer (ALB). The…

Creating an AWS CloudFormation template for the current infrastructure design enables consistent, repeatable, and automated deployment of the entire application stack to the second AWS Region, minimizing administrative overhead.

Documenting infrastructure in the AWS Management Console is a manual process and does not minimize administrative overhead for replication compared to Infrastructure as Code.

Weighted routing distributes traffic based on predefined weights, which is less optimal than latency-based routing for automatically directing users to the best performing region to improve access time.

Updating the Route 53 hosted zone record to use latency-based routing ensures that users are automatically directed to the nearest healthy application instance, providing improved access times and distributing traffic across regions.

While enabling DynamoDB Streams on an existing table is a step for Global Tables, creating a *new* table might be required if the existing table's schema (e.g., specific LSI configurations) is incompatible with Global Tables, making F a more comprehensive initial step in some scenarios.

To establish multi-region replication for DynamoDB, it is necessary to create a new DynamoDB table (if the existing one is incompatible or for a fresh Global Table instance) and enable DynamoDB Streams, which is a prerequisite for configuring it as a Global Table for active-active data replication.
