Databricks-DE-Assoc Working with Lakeflow Jobs Practice Question
A data engineer is creating a Lakeflow Job that must run a Python script stored in DBFS. The engineer wants to ensure the script is executed with the correct dependencies and environment. Which task type should be used?
⚠ Common exam trap
The trap here is assuming a notebook task can run any Python file; notebook tasks specifically require a notebook format and do not execute standalone .py scripts.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Python script task
Lakeflow Jobs offer a dedicated Python script task type that runs a Python file from DBFS or other storage locations. It supports specifying libraries and environment settings, ensuring the script runs with the correct dependencies. Notebook, JAR, and pipeline tasks serve different purposes and cannot directly execute a standalone Python script with its own environment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
JAR task
Why it's wrong here
JAR tasks are used to run Java applications packaged as JAR files. They are not suitable for executing Python scripts, as they expect a Java main class and JVM environment. Using a JAR task for a Python script would fail because the script cannot be executed by the Java runtime.
- ✗
Notebook task
Why it's wrong here
Notebook tasks are designed to run Databricks notebooks, not standalone Python scripts stored in DBFS. While you can use %run or import mechanisms within a notebook, the task type itself expects a notebook path. It does not directly execute a .py file from DBFS with its own environment, so it is not the correct choice.
- ✗
Pipeline task
Why it's wrong here
Pipeline tasks are used to trigger Delta Live Tables pipelines, which are defined in declarative notebooks or SQL. They are not designed to run arbitrary Python scripts. While a pipeline can contain Python code, it operates within the DLT framework and does not execute a standalone script from DBFS.
- ✓
Python script task
Why this is correct
The Python script task type in Lakeflow Jobs allows you to specify a Python file stored in DBFS, Unity Catalog volumes, or cloud storage. It executes the script with the specified libraries and environment, making it ideal for running standalone Python scripts with dependencies. This directly matches the requirement.
