{"question_number": 5, "question_summary": "AWS Glue feature for incremental data processing of files uploaded to S3", "correct_answer": "C", "explanation": "AWS Glue Job Bookmarks track the state of a job run - specifically which S3 objects (or rows) have already been processed - so that subsequent runs only process new or changed data. This is the native AWS Glue mechanism for incremental processing with no custom tracking code required. Workflows (option A) orchestrate multiple Glue jobs and crawlers but do not themselves filter already-processed data. Triggers (option B) schedule or event-drive job executions but do not track data state. Classifiers (option D) identify the schema/format of data sources and have nothing to do with incremental processing.", "generated_by": "claude-sonnet", "llm_judge_score": 5}
