{"question_number": 8, "question": "While chairing a team session, you are telling the team members about the Azure Cosmos DB Emulator. Which of the following statements is NOT true about Azure Cosmos DB Emulator?", "correct_answer": "B", "explanation": "The correct answer is B, because the statement about the primary key is false. The Azure Cosmos DB Emulator uses a single, fixed, well-known authentication key that is hardcoded and CANNOT be changed by the user - it is the same across all emulator installations. The statement in option B implies that the key can be modified ('You can even...'), which is incorrect. Options A, C, and D are all TRUE statements: (A) The emulator provides a local development environment that mimics Cosmos DB without needing an Azure subscription. (C) The emulator does NOT support multi-region replication - it is a single-node local emulator. (D) The emulator does NOT support all consistency levels available in the cloud service; it operates with limited consistency level support. Since the question asks for the statement that is NOT true, option B is the answer.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
