                                                      • B. Utilize Airflow logs (scheduler, worker) to analyze detailed error messages and stack traces.
                                                      • C. Rely on the error message displayed on the Airflow UI, even if it's generic.
                                                      • D. Inspect the code of failed tasks directly within the Airflow web Ul for potential issues.

                                                      You're building an Airflow DAG that consists of multiple interdependent ETL pipelines. How can you ensure they execute in the correct order and avoid conflicts?

                                                      • A. Schedule each pipeline separately with appropriate scheduling intervals.
                                                      • B. Utilize Airflow sub-DAGs to group related tasks and define dependencies between them.
                                                      • C. Run all pipelines simultaneously, assuming they are independent.
                                                      • D. Implement a custom script to manage the execution order of the pipelines.
