Add the following multiple choice questions and answers and explanations verbatim (DO NOT change the given wording). ----------------------------------------------------- New Question 1: "Which of the following is an example of direct service exposure or accurately describes direct service exposure in a microservices architecture?" Choice A: "Using a single endpoint to handle requests for all microservices." Choice B: "Interacting with separate endpoints for file uploads, downloads, and metadata retrieval." Choice C: "Utilizing a cloud service that combines all operations into one endpoint." Choice D: "Accessing file upload and download functionalities through a unified API." Correct answer: B Explanation: In a cloud storage service, clients directly interact with different endpoints for various functionalities. Direct service exposure requires clients to manage multiple endpoints, complicating interactions. ----------------------------------------------------- New Question 2: "What is a possible drawback of using an API Gateway?" Choice A: "It eliminates the need for any security measures." Choice B: "It can introduce a single point of failure in the architecture." Choice C: "It requires more endpoints for client interactions." Choice D: "It reduces the control clients have over individual services." Correct answer: B Explanation: API Gateways can create single points of failure, which is a significant concern in system architecture. ----------------------------------------------------- New Question 3: "What is a significant security feature provided by an API Gateway?" Choice A: "Automatic scaling of services" Choice B: "Direct access to all databases" Choice C: "Centralized billing for services" Choice D: "Centralized authentication and SSL termination" Correct answer: D Explanation: The API Gateway enhances security through centralized authentication and the termination of SSL, adding a layer of protection. ----------------------------------------------------- -----------------------------------------------------
