Add the following multiple choice questions and answers and explanations verbatim (DO NOT change the given wording). ========================================== New Question 1: What does the "clear contract" advantage of RPC refer to? Choice A: The use of standard HTTP methods. Choice B: The explicit definition of procedures between client and server. Choice C: The ability to handle multiple data formats. Choice D: The independence from server-side implementations. Correct answer: B Explanation: The "clear contract" in RPC means that the procedures or methods are explicitly defined between the client and server, outlining how they interact. ========================================== New Question 2: In what scenario is REST more appropriate than RPC according to the article? Choice A: When implementing tightly coupled server operations. Choice B: For internal microservices communication requiring high efficiency. Choice C: For public APIs requiring scalability and a uniform interface. Choice D: When requiring stateful interactions between client and server. Correct answer: C Explanation: REST is generally more suited for web services and public APIs where scalability, caching, and a uniform interface are important. ========================================== New Question 3: What distinguishes REST as an architectural style compared to RPC as a protocol? Choice A: REST uses binary data formats, while RPC uses text-based formats. Choice B: REST relies on standard HTTP methods, while RPC focuses on remote method execution. Choice C: REST is tightly coupled to server methods, while RPC is resource-oriented. Choice D: REST maintains client context between requests, while RPC is stateless. Correct answer: B Explanation: REST is an architectural style that uses standard HTTP methods to manipulate resources, whereas RPC is a protocol focused on executing remote methods. ========================================== New Question 4: Which data serialization format is specifically associated with enhancing RPC performance? Choice A: XML Choice B: JSON Choice C: Protocol Buffers Choice D: YAML Correct answer: C Explanation: Protocol Buffers, used in binary RPC implementations like gRPC, improve performance by being more efficient in data transfer. ==========================================
