Q96 — AWS DVA-C02 Ch.2

Question 96 of 100 | ← Chapter 2

A company is delivering daily updated commodity pricing information as a publicly accessible, unauthenticated read-only API over the internet. The company uses Amazon API Gateway and AWS Lambda to develop these APIs. The service has become very popular, and the company wants to improve API response latency. Which action would help the company achieve this goal?

• A. Enable API caching in API Gateway. ✓
• B. Configure API Gateway to use an interface VPC endpoint.
• C. Enable Cross-Origin Resource Sharing (CORS) for the API.
• D. Configure usage plans and API keys in API Gateway.

Correct Answer: A. Enable API caching in API Gateway.

Explanation

Enabling API caching is an effective method to improve API response latency. It caches previous API responses, reducing requests to the backend service. While the other options are important for API management and security, they do not directly improve API response latency.
