Hands-On Quiz — Production Operations & Governance

Practice Exercises

Exercise 1: Custom Role

Create a role that can view DAG run history and task logs but cannot trigger runs, edit Connections, or manage users. Verify a user assigned only that role actually can't perform those restricted actions.

Exercise 2: SLA Miss Handling

Add an sla_miss_callback to a DAG and a task with a deliberately short SLA. Trigger it against a task that takes longer than the SLA and confirm the callback fires.

Exercise 3: Safe Backfill

Take a DAG using the delete-then-insert idempotency pattern from the Best Practices module, and backfill 7 days of historical data. Confirm re-running the same backfill a second time produces identical results rather than duplicate rows.
