Explanation

{"question_number": 4, "question": "A developer needs to upload a local file by using the REST API and gets an error code using cURL.", "correct_answer": "B", "explanation": "The most common cause of an error when accessing a REST API without any authentication-related header is an HTTP 401 Unauthorized response. The fix is to add an Authorization header containing the access token (e.g., 'Authorization: Bearer <token>'). Option A is wrong because changing Content-Type to JSON would not fix an authentication error, and file uploads typically use multipart/form-data. Option C (username-password) may apply to Basic Auth, but when an API uses token-based auth, an access token header is the correct approach. Option D is wrong because uploading a file requires a POST/PUT, not GET.", "generated_by": "claude-sonnet", "llm_judge_score": 3}
