{"question_number": 2, "question": "A 401 HTTP response code is returned when calling a REST API. What is the error state identified by this response code?", "correct_answer": "C", "explanation": "The correct answer is C. HTTP 401 'Unauthorized' means the request lacks valid authentication credentials. The client must authenticate (e.g., provide a valid token or credentials) before access is granted. It does not mean the client is recognized but lacks permission-that would be 403 Forbidden (answer B). Answer A describes a 400 Bad Request error. Answer D describes a 404 Not Found error. The subtle but important distinction: 401 = not authenticated yet; 403 = authenticated but not authorized.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
