Databricks Certified Data Engineer Professional — Question 29

A junior developer complains that the code in their notebook isn't producing the correct results in the development environment. A shared screenshot reveals that while they're using a notebook versioned with Databricks Repos, they're using a personal branch that contains old logic. The desired branch named dev-2.3.9 is not available from the branch selection dropdown.
Which approach will allow this developer to review the current logic for this notebook?

Answer options

• A. Use Repos to make a pull request use the Databricks REST API to update the current branch to dev-2.3.9
• B. Use Repos to pull changes from the remote Git repository and select the dev-2.3.9 branch.
• C. Use Repos to checkout the dev-2.3.9 branch and auto-resolve conflicts with the current branch
• D. Merge all changes back to the main branch in the remote Git repository and clone the repo again
• E. Use Repos to merge the current branch and the dev-2.3.9 branch, then make a pull request to sync with the remote repository

Correct answer: B

Explanation

The correct answer is B because it directly addresses the need to pull the latest changes from the remote repository and switch to the desired branch dev-2.3.9. Options A, C, D, and E involve unnecessary steps or do not effectively achieve the goal of reviewing the current logic in the correct branch.
