DOP-C02 Question #300: Real Exam Question with Answer & Explanation

Question

A company operates a globally deployed product out of multiple AWS Regions. The company's DevOps team needs to use Amazon API Gateway to deploy an API to support the product. The API must be deployed redundantly. The deployment must provide independent availability from each company location. The deployment also must respond to a custom domain URL and must optimize performance for the API user requests. Which solution will meet these requirements?

Options

• ADeploy an API Gateway edge-optimized API endpoint in the us-east-1 Region. Create an API
• BDeploy an API Gateway regional API endpoint in the us-east-1 Region. Integrate the API
• CDeploy an API Gateway regional API endpoint in every AWS Region where the company's
• DDeploy an API Gateway edge-optimized API endpoint in the us-east-1 Region. Create an Amazon

Explanation

Regional API Gateway endpoints: Deploying API Gateway endpoints in every region where the product is deployed ensures that each region operates independently, providing redundancy and high availability. This approach satisfies the requirement for independent availability from each company location. Creating custom domains for each regional API allows you to map the API to your desired domain name, maintaining a consistent and professional URL structure for the global deployment. Latency-based routing allows traffic to be routed to the region that provides the lowest latency for the user. This optimizes performance by directing users to the closest regional API endpoint, improving the responsiveness of the API. This solution meets the key requirements: redundant deployments across multiple regions, independent availability for each region, the use of a custom domain, and optimized performance for user requests by using latency-based routing.
