Databricks Certified Data Engineer - Associate

Explanation

Correct Answer: D - Databricks Repos supports the use of multiple branches

Why this is correct:

1. Multiple Branch Support: Databricks Repos integrates with Git repositories (GitHub, GitLab, Bitbucket, etc.), which inherently support branching workflows. This allows teams to:

   • Create feature branches for new development
   • Use development/staging/production branches
   • Implement GitFlow or similar branching strategies
   • Collaborate on different versions simultaneously

2. Built-in Notebook Versioning Limitations: While Databricks' built-in notebook versioning does allow reverting to previous versions (option A), it lacks Git integration features like:

   • Branching and merging capabilities
   • Pull request workflows
   • Code review processes
   • Integration with CI/CD pipelines

3. Analysis of Other Options:

   • A: Both built-in versioning and Databricks Repos allow reverting to previous versions, so this is not a unique advantage of Repos.
   • B: Both solutions are housed within the Databricks platform, so this is not a distinguishing advantage.
   • C: Commenting on specific changes is typically a feature of Git platforms (like GitHub/GitLab) rather than Databricks Repos itself, though Repos enables this workflow through Git integration.

Key Takeaway: The primary advantage of Databricks Repos over built-in notebook versioning is its Git integration, which enables modern software development practices including branching, pull requests, and collaboration workflows that are essential for team-based development and production deployments.
