Complete Answer Key

October 2026 practice

Checked against Apache Airflow 3.3.2, the stable release dated 17 September 2026. New DAG files import from airflow.sdk. Dataset was renamed to Asset. @task is the default for Python. PythonOperator still runs, and it is the migration path from older DAGs.

The answer key matches the practice set. It does not grant an external certificate. Explanations that mention a schedule should say schedule, not schedule_interval, and Asset, not Dataset, when they mean the Airflow 3 object.
