Question 508

A company is using a single AWS Region for its ecommerce website. The website includes a web application that runs on several Amazon EC2 instances behind an Application Load Balancer (ALB). The website also includes an Amazon DynamoDB table. A custom domain name in Amazon Route 53 is linked to the ALB. The company created an SSL/TLS certificate in AWS Certificate Manager (ACM) and attached the certificate to the ALB. The company is not using a content delivery network as part of its design.

The company wants to replicate its entire application stack in a second Region to provide disaster recovery, plan for future growth, and provide improved access time to users. A solutions architect needs to implement a solution that achieves these goals and minimizes administrative overhead.

Which combination of steps should the solutions architect take to meet these requirements? (Choose three.)

Create an AWS CloudFormation template for the current infrastructure design. Use parameters for important system values, including Region. Use the CloudFormation template to create the new infrastructure in the second Region.

Use the AWS Management Console to document the existing infrastructure design in the first Region and to create the new infrastructure in the second Region.

Update the Route 53 hosted zone record for the application to use weighted routing. Send 50% of the traffic to the ALB in each Region.

Update the Route 53 hosted zone record for the application to use latency-based routing. Send traffic to the ALB in each Region.

Update the configuration of the existing DynamoDB table by enabling DynamoDB Streams. Add the second Region to create a global table.

Create a new DynamoDB table. Enable DynamoDB Streams for the new table. Add the second Region to create a global table. Copy the data from the existing DynamoDB table to the new table as a one-time operation.

Correct Answer: A, D, E

To replicate the entire application stack in a second Region with minimal administrative overhead, the solutions architect should take the following steps: Create an AWS CloudFormation template for the current infrastructure design to easily replicate it in other Regions. Update the Route 53 hosted zone record for the application to use latency-based routing which directs traffic based on the lowest latency to users, ensuring improved access time. Enable DynamoDB Streams for the existing DynamoDB table and create a global table to ensure the data is replicated across both Regions smoothly and efficiently.
