Answer: They can create a new task in the existing Job and then add it as a dependency of the original task.
## Explanation **Correct Answer: B** **Why Option B is correct:** 1. The requirement is to run a new notebook **prior to** the original task 2. In Databricks Jobs, task dependencies define execution order - when Task A depends on Task B, Task B must complete successfully before Task A can start 3. By creating a new task and adding it as a dependency of the original task, the new task will run first, then the original task **Why other options are incorrect:** - **Option A**: Cloning and updating the existing task would replace the original task rather than adding a new task to run before it - **Option C**: This would make the original task a dependency of the new task, meaning the original task would run first (opposite of what's needed) - **Option D**: Creating a new job from scratch is unnecessary and would require additional setup; it's more efficient to modify the existing job **Key Concept:** In Databricks Jobs, task dependencies control execution order. To run Task A before Task B, make Task A a dependency of Task B.
