Question

A financial company hosts a web application on AWS. The application uses an Amazon API Gateway Regional API endpoint to give users the ability to retrieve current stock prices. The company’s security team has noticed an increase in the number of API requests. The security team is concerned that HTTP flood attacks might take the application offline. A solutions architect must design a solution to protect the application from this type of attack. Which solution meets these requirements with the LEAST operational overhead?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Create a Regional AWS WAF web ACL with a rate-based rule. Associate the web ACL with the API Gateway stage. Amazon API Gateway is a fully managed front door for creating and securing APIs at scale. AWS WAF protects web applications from common exploits and malicious requests.
