Sample Questions

Question 1
What is the primary advantage of using the @task decorator (TaskFlow API) over the classic PythonOperator?
The @task decorator allows tasks to run on separate Kubernetes pods automatically
The @task decorator eliminates boilerplate: return values automatically become XCom, and passing return values between @task functions creates implicit dependencies
The @task decorator runs tasks faster because it bypasses the metadata database
The @task decorator enables tasks to access global Python variables at parse time
Question 2
In the following TaskFlow API snippet, what is the task dependency created? ```python @dag def my_dag(): data = extract() result = transform(data) load(result) ```
All three tasks run in parallel
extract → transform → load, with XCom values passed between them automatically
Only extract and load are connected; transform is independent
The dependencies must be explicitly set with >> operators as well
Question 3
How do you mix a classic BashOperator with a TaskFlow API @task function and create a dependency where the @task runs after the BashOperator?
It is not possible to mix classic operators with TaskFlow API in the same DAG
Use the >> operator: bash_task >> taskflow_func()
Wrap the BashOperator in a @task decorator to make it compatible
Use the depends_on=[bash_task] parameter in the @task decorator
Question 4
What does the @task.branch decorator (TaskFlow API) return, and what effect does it have on downstream tasks?
It returns a boolean; True continues all downstream tasks, False skips them
It returns a task_id string (or list of task_ids); only those tasks run, the rest are marked skipped
It returns an XCom value that BranchPythonOperator reads to decide the branch
It returns a DAG run configuration that changes the schedule
Question 5
A DAG uses BranchPythonOperator to choose between branch_a and branch_b. A final 'notify' task must run regardless of which branch executes. What trigger_rule should 'notify' have?
all_success (default)
all_done
none_failed_min_one_success
none_failed
