Databricks Certified Data Engineer - Associate

The correct answer is E. Merge.

Explanation:

Databricks Repos provides integrated Git functionality for many common operations, but there are limitations:

1. Commit - Can be performed within Databricks Repos
2. Pull - Can be performed within Databricks Repos
3. Push - Can be performed within Databricks Repos
4. Clone - Can be performed within Databricks Repos (you can clone repositories directly into Databricks)
5. Merge - Cannot be performed within Databricks Repos. Merge operations must be performed outside of Databricks, typically using Git command line or other Git tools.

Databricks Repos supports basic Git operations for version control, but more complex operations like merging branches require external Git tools. This is because Databricks Repos is designed for collaborative development and version control of notebooks and other workspace objects, but doesn't include all the advanced Git features available in full Git clients.
