Exam Certified Data Engineer Associate topic 1 question 37 discussion

It seems there is some confusion on what dependency means in this case. Option B is correct because adding the new task as a dependency of the original task means that the new task will run BEFORE the original task, which is the goal defined in the question.

B is the right answer.

In Databricks Jobs, you can manage task dependencies within a single job. If you want to add a new task that needs to run before the original task due to an upstream issue, the appropriate approach would be to: Create a new task: This new task would run the notebook that addresses the upstream data issue. Add it as a dependency of the original task: By making the new task dependent on the original task, you ensure that the new task runs first, and only after its successful completion will the original task run. This approach ensures that the sequence of tasks is correctly managed in a single job, with dependencies explicitly defined.

C. They can create a new task in the existing Job and then add the original task as a dependency of the new task. Why this is correct: In Databricks, you can set up a task dependency chain by adding a new task and specifying that the original task depends on the new one. This ensures that the new task will run first, followed by the original task.

Both B and C involve dependencies between tasks, but the difference is in how the dependencies are structured: B: "They can create a new task in the existing Job and then add it as a dependency of the original task." In this case, the new task is added as a prerequisite (dependency) for the original task. This means the new task will run first, and once it's completed, the original task will run. C: "They can create a new task in the existing Job and then add the original task as a dependency of the new task." In this case, the original task is added as a dependency for the new task, meaning the new task will wait for the original task to finish before running. The correct answer is B: You want the new task (the one handling the upstream issue) to run before the original task, so it should be set as a dependency of the original task.

B is correct as Redwings538 says

I think the Correct answer is C. Because as per the statement in the question "they need to set up another task to run a new notebook prior to the original task." i.e. original task should run AFTER the new task. So, By creating a new task in the existing job and setting the original task as a dependency of the new task, the data engineer ensures that the new notebook runs first, followed by the original task. This approach maintains the sequence of execution required to address the upstream data issue.

Below is the info I am convinced after checking with AI..... Here's the break down the differences between options B and C: Option B: Create a new task in the existing Job and then add it as a dependency of the original task: Result: The new task will run after the original task. Option C: Create a new task in the existing Job and then add the original task as a dependency of the new task: Result: The new task will run before the original task. Summary: Option B: Original task → New task Option C: New task → Original task In your case, Option C is the correct choice because you need the new task to run first to resolve the upstream data issue before the original task executes.

C is correct because it correctly handles the sequence of execution. By creating a new task in the existing Job and adding the original task as a dependency of the new task, the new task will run first, and once it completes successfully, the original task will run. This ensures that the upstream data issue is addressed before the original task runs.

B is the right answer.

original depends on new

C because the new task has to run prior the original one

Just got 100% on the test. B was correct.

This has become more of a English grammatical test as the word dependency is confusing people. When the Original task has a dependency on the new task this means the original task needs to depend on the new task. So it's Option C.

The data engineer can create a new task in the existing Job and then add the original task as a dependency of the new task (Option C). This way, the new task will run first, and once it’s completed, the original task will run. Here are the steps to do this: Click Workflows in the sidebar and click New and select Job. The Tasks tab appears with the create task dialog. Replace Add a name for your job… with your job name. Enter a name for the task in the Task name field. In the Type drop-down menu, select the type of task to run. Configure the cluster where the task runs. To add dependent libraries, click + Add next to Dependent libraries. You can pass parameters for your task. Please note that the exact process may vary depending on the specific configurations and permissions set up in your workspace. It’s always a good idea to consult with your organization’s IT or data governance team to ensure the correct procedures are followed.

Answer is C

I am pretty sure its B - "they need to set up another task to run a new notebook prior to the original task." - so NEW task need to run BEFORE ORIGINAL task. So NEW TASK should be DEPENDENCY of ORIGINAL TASK (or in other words: original task is dependent on new task)
