Databricks-Certified-Professional-Data-Engineer: Databricks Certified Data Engineer Professional Junior Practice Questions

The data engineer team is configuring environment for development testing, and production before beginning migration on a new data pipeline. The team requires extensive testing on both the code and data resulting from code execution, and the team want to develop and test against similar production data as possible. A junior data engineer suggests that production data can be mounted to the development testing environments, allowing pre production code to execute against production data. Because all users have Admin privileges in the development environment, the junior data engineer has offered to configure permissions and mount this data for the team. Which statement captures best practices for this situation?

• AA. Because access to production data will always be verified using passthrough credentials it is safe to mount data to any Databricks development environment.
• BB. All developer, testing and production code and data should exist in a single unified workspace; creating separate environments for testing and development further reduces risks.
• CC. In environments where interactive code will be executed, production data should only beaccessible with read permissions; creating isolated databases for each environment further reduces risks.
• DD. Because delta Lake versions all data and supports time travel, it is not possible for user error or malicious actors to permanently delete production data, as such it is generally safe to mount production data anywhere.

A junior data engineer has configured a workload that posts the following JSON to the Databricks REST API endpoint 2.0/jobs/create. Assuming that all configurations and referenced resources are available, which statement describes the result of executing this workload three times?

• AA. Three new jobs named "Ingest new data" will be defined in the workspace, and they will each run once daily.
• BB. The logic defined in the referenced notebook will be executed three times on new clusters with the configurations of the provided cluster ID.
• CC. Three new jobs named "Ingest new data" will be defined in the workspace, but no jobs will be executed.
• DD. One new job named "Ingest new data" will be defined in the workspace, but it will not be executed.
• EE. The logic defined in the referenced notebook will be executed three times on the referenced existing all purpose cluster.
