Astronomer Apache Airflow 3 Fundamentals: Monitoring, the UI, and the CLI Practice Questions

5 free sample questions from the Monitoring, the UI, and the CLI domain, with answers and explanations. The full Apache Airflow 3 Fundamentals bank has 55 questions across 4 domains. Questions are scenario-based and written from the official Astronomer exam guide.

1.

Which Airflow UI view shows a grid of DAG runs and their task instances over time, making it easy to spot failures across runs?

  • A. The Admin menu
  • B. The Grid view✓ Correct
  • C. The Variables page
  • D. The Connections page
Explanation

The Grid view displays DAG runs as columns and tasks as rows, color-coded by state, so you can quickly see which task instances failed across runs. Connections (D) and Variables (C) are admin config pages, and the Admin menu (A) is navigation, not a run-monitoring view.

2.

Which CLI command lists all DAGs known to the Airflow instance?

  • A. airflow dags list✓ Correct
  • B. airflow variables get
  • C. airflow webserver
  • D. airflow tasks run
Explanation

airflow dags list prints the DAGs Airflow has parsed. tasks run (D) runs a task, variables get (B) reads a variable, and webserver (C) starts the UI server — none lists DAGs.

3.

Which UI view helps you see on which calendar days a DAG ran and how those runs turned out over time?

  • A. The Variables page
  • B. The Calendar view✓ Correct
  • C. The Graph view
  • D. The Connections page
Explanation

The Calendar view shows DAG run history by date, giving a heatmap-like overview of runs and their outcomes over time. The Connections (D) and Variables (A) pages are configuration, and the Graph view (C) shows task structure for a run, not a calendar history.

4.

Which Airflow UI view displays the DAG's tasks and their dependencies as a graph?

  • A. The Grid view
  • B. The Graph view✓ Correct
  • C. The Calendar view
  • D. The Logs tab only
Explanation

The Graph view renders the DAG's tasks and dependency edges, showing the workflow structure and each task's state for a selected run. The Grid view (A) is a time grid, the Calendar view (C) shows run history by date, and Logs (D) show task output.

5.

You fixed a bug and want to re-run a failed task (and its downstream) for a specific DAG run. What is the standard UI action?

  • A. Drop the metadata database
  • B. Clear the task instance(s), which re-queues them to run again✓ Correct
  • C. Delete the entire DAG
  • D. Change the dag_id
Explanation

Clearing a task instance resets its state so the scheduler re-runs it (optionally with downstream tasks) — the standard retry/rerun action in the UI. Deleting the DAG (C), changing the dag_id (D), or dropping the database (A) are destructive and incorrect.
