20+ practice questions focused on Working with Lakeflow Jobs — one of the most tested topics on the Databricks Certified Data Engineer Associate exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Working with Lakeflow Jobs PracticeA data engineer wants to schedule a Databricks Job to run every Tuesday at 8:30 AM UTC. Which cron expression correctly represents this schedule?
Explanation: Databricks Jobs support Quartz cron syntax for precise scheduling. A valid cron expression consists of fields for seconds, minutes, hours, day of month, month, and day of week. Understanding cron syntax ensures production pipelines execute automatically at expected maintenance windows and business hours.
When configuring a Databricks Job, which notification option ensures that a team is alerted specifically when a job fails?
Explanation: In the Databricks Jobs UI, the specific setting is found under 'Notifications' where you can add an email address and select the 'On failure' trigger. The option 'Email notifications on failure' is a descriptive summary, but the UI specifically refers to 'Email notifications' with a trigger condition. Additionally, the explanation is generic and does not explain why the other options are incorrect in the context of Databricks functionality.
A data engineer is configuring a Lakeflow Job with multiple tasks. The engineer wants to ensure that the job can be repaired and that only failed tasks are re-run without re-executing successful tasks. Which TWO features or configurations enable this behavior? (Choose two.)
Explanation: Repair runs in Lakeflow Jobs allow re-execution of only failed or skipped tasks, preserving the results of successful tasks. This is enabled by the "Repair run" feature, which can be initiated from the job run details page. Autoscaling, "Run if" conditions, and frequent schedules do not provide this selective re-execution capability, so they are incorrect for this scenario.
A data engineer is configuring a Lakeflow Job with a task that runs a Python wheel. The engineer needs to ensure that the task can access a specific set of Python libraries that are not included in the Databricks Runtime. The engineer wants to avoid installing these libraries at runtime using %pip. Which TWO of the following approaches are valid for making these libraries available to the task? (Choose two.)
Explanation: The two valid approaches are attaching libraries to the job cluster as cluster-scoped libraries and specifying them in the task's dependent libraries. Both methods ensure the libraries are installed before task execution, leveraging built-in job configuration rather than runtime installation.
A data engineer is building a Lakeflow Job with three tasks: bronze_ingest, silver_transform, and gold_aggregate. The engineer wants gold_aggregate to run only when silver_transform succeeds, and wants the job to skip gold_aggregate without marking the whole job as failed when silver_transform is skipped. Which two configuration choices support this behavior? (Choose two.)
Explanation: To run a downstream task only on upstream success and to skip it without failing the job, the dependency condition must evaluate correctly when the upstream is skipped, and the job must treat skipped tasks as a non-failure. The at-least-one-succeeded condition ensures gold_aggregate runs only when silver_transform succeeds, and the job-level skip handling keeps the run from being marked failed. Other settings affect earlier edges or retries and do not satisfy the requirement.
