Explanation
{"question_number": 1, "correct_answer": "B", "explanation": "Data masking replaces sensitive or real data with fictitious but structurally similar placeholders. The goal is to render the data useless to unauthorized parties (e.g., in a breach) while preserving its format and utility for testing, reporting, or analytics. In this scenario, refugee status, income, ID numbers, and other PII are substituted with randomized values - the defining characteristic of data masking. Data encoding converts data into a specific format (e.g., Base64), data recoding changes categorical values (e.g., 'Male' → 1), and data formatting adjusts presentation/structure - none of these match the described privacy-preserving substitution.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
