Answer:
A) As an API Gateway for routing and filtering
Explanation:
Spring Cloud Zuul is used as an API Gateway that provides routing and filtering functionalities in a microservices architecture. Zuul acts as a front door for all requests, routing them to the appropriate microservices based on the defined rules. It also offers features like authentication, authorization, rate limiting, and logging, which can be applied to incoming requests before they reach the backend services.
Zuul helps centralize cross-cutting concerns, making it easier to manage and secure communication between clients and microservices.
