Exam Certified Data Engineer Professional topic 1 question 153 discussion

Actual exam question from Databricks's Certified Data Engineer Professional
Question #: 153
Topic #: 1
[All Certified Data Engineer Professional Questions]

The data engineering team is configuring environments 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 wants to develop and test against data as similar to production data as possible.

A junior data engineer suggests that production data can be mounted to the development and 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?

  • A. All development, testing, and production code and data should exist in a single, unified workspace; creating separate environments for testing and development complicates administrative overhead.
  • B. In environments where interactive code will be executed, production data should only be accessible with read permissions; creating isolated databases for each environment further reduces risks.
  • C. Because access to production data will always be verified using passthrough credentials, it is safe to mount data to any Databricks development environment.
  • D. 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.

Selected Answer: B
Production data should be maximum secured against intentional and unintentional modifications by developers or workspace/UC admins. So setting it up with read only access and in different catalog or schema/database per environment is best approach.
