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?

A. Create an Amazon CloudFront distribution in front of the API Gateway Regional API endpoint with a maximum TTL of 24 hours.
B. Create a Regional AWS WAF web ACL with a rate-based rule. Associate the web ACL with the API Gateway stage.
C. Use Amazon CloudWatch metrics to monitor the Count metric and alert the security team when the predefined rate is reached.

Rta B: AWS WAF es un firewall de aplicaciones web que ayuda a proteger las aplicaciones web y las API de ataques. Le permite configurar un conjunto de reglas (denominadas lista de control de acceso web (Web ACL)) que permiten, bloquean o cuentan solicitudes web en función de las reglas y condiciones de seguridad web personalizables que defina.
