[All Databricks Certified Data Engineer Associate Exam Questions]

A Delta Live Table pipeline includes two datasets defined using streaming live table. Three datasets are defined against Delta Lake table sources using live table.

The table is configured to run in Production mode using the Continuous Pipeline Mode.

What is the expected outcome after clicking Start to update the pipeline assuming previously unprocessed data exists and all definitions are valid?

AAll datasets will be updated once and the pipeline will shut down. The compute resources will be terminated.

BAll datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist to allow for additional testing.

CAll datasets will be updated once and the pipeline will shut down. The compute resources will persist to allow for additional testing.

DAll datasets will be updated at set intervals until the pipeline is shut down. The compute resources will be deployed for the update and terminated when the pipeline is stopped.

Show Suggested Answer

Suggested Answer: D

In Delta Live Tables (DLT), when configured to run in Continuous Pipeline Mode, particularly in a production environment, the system is designed to continuously process and update data as it becomes available. This mode keeps the compute resources active to handle ongoing data processing and automatically updates all datasets defined in the pipeline at predefined intervals. Once the pipeline is manually stopped, the compute resources are terminated to conserve resources and reduce costs. This mode is suitable for production environments where datasets need to be kept up-to-date with the latest data.

I'm not sure, but I think it might be D. The compute resources will be deployed for the update and terminated when the pipeline is stopped.

I think the answer is B. The pipeline will continuously update the datasets at set intervals until it's shut down, and the compute resources will persist for further testing.

I agree with you. It makes sense that the compute resources would stay active for testing purposes.
