Q16 — AWS DVA-C02 Ch.2

Question 16 of 100 | ← Chapter 2

A company is building an application on AWS. The application’s backend includes a REST API in Amazon API Gateway. Frontend application developers need to continue working before the backend API is ready for integration. The company requires a solution enabling frontend developers to proceed with development. Which solution satisfies these requirements with maximum operational efficiency?

• A. Configure mock integrations for the API Gateway API methods. ✓
• B. Integrate a Lambda function with API Gateway and return mock responses.
• C. Add a new API endpoint to the API Gateway stage and return mock responses.
• D. Configure proxy resources for the API Gateway API methods.

Correct Answer: A. Configure mock integrations for the API Gateway API methods.

Explanation

Option A recommends configuring mock integrations for API Gateway API methods. Mock integrations simulate backend responses without requiring actual backend services or functions, allowing frontend developers to proceed immediately and independently. This approach is operationally most efficient. Options B, C, and D require deploying and managing Lambda functions or actual backend infrastructure, introducing unnecessary overhead and complexity when only mock behavior is needed.
