Explanation
{"question_number": 6, "question": "What is a difference between REST and RPC API styles?", "correct_answer": "D", "explanation": "REST (Representational State Transfer) is inherently stateless - each HTTP request must contain all information necessary to process it, with no session state stored on the server between requests. RPC (Remote Procedure Call) can be stateful, maintaining session context between calls. Option A is wrong because both REST and RPC commonly use JSON (REST also supports XML, plain text, etc.; RPC doesn't dictate HTML). Option B is incorrect - REST has defined constraints/styles, while RPC has multiple implementations (gRPC, XML-RPC, JSON-RPC). Option C is inaccurate; RPC uses various verbs (CALL), while REST uses HTTP methods semantically (GET, POST, PUT, DELETE) according to resource actions.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
