Câu 69: Databricks Certified Data Engineer Professional

A Databricks job has been configured with 3 tasks, each of which is a Databricks notebook. Task A does not depend on other tasks. Tasks B and C run in parallel, with each having a serial dependency on Task A. If task A fails during a scheduled run, which statement describes the results of this run?

1. A. Because all tasks are managed as a dependency graph, no changes will be committed to the Lakehouse until all tasks have successfully been completed.
2. B. Tasks B and C will attempt to run as configured; any changes made in task A will be rolled back due to task failure.
3. C. Unless all tasks complete successfully, no changes will be committed to the Lakehouse; because task A failed, all commits will be rolled back automatically.
4. D. Tasks B and C will be skipped; some logic expressed in task A may have been committed before task failure. — đáp án hiện tại
