Q96 — AWS DVA-C02 Ch.1

Question 96 of 100 | ← Chapter 1

A company is building a microservices-based consumer-facing application. Each consumer can connect to one or more services. This has resulted in a complex architecture that is difficult to manage and scale effectively. The company needs a single interface to manage these consumer-facing services. Which AWS service should be used to refactor this architecture?

• A. AWS Lambda
• B. AWS X-Ray
• C. Amazon SQS
• D. Amazon API Gateway ✓

Correct Answer: D. Amazon API Gateway

Explanation

In this scenario, the company requires a unified interface to manage consumer-facing services while handling complex routing across multiple services. Amazon API Gateway is purpose-built for this use case—it provides a scalable, fully managed API service enabling developers to create, publish, maintain, monitor, and secure REST and WebSocket APIs of any size. By leveraging API Gateway, the company establishes a single entry point to route and manage all consumer-facing service requests, while benefiting from AWS scalability and elasticity to accommodate growth and change. Therefore, the correct answer is D.
