Exam DBDEA Topics: cicd Difficulty: medium

A data engineer is refactoring ingestion notebooks on the `feature/dq-checks` branch checked out in their Git Folder. While waiting for CI, they must also reproduce a bug that a teammate already fixed on the `hotfix/schema-fix` branch, running both branches' notebooks in the same workspace at the same time to compare outputs. What should the engineer do?

  1. A. Keep switching the existing Git Folder between feature/dq-checks and hotfix/schema-fix whenever they need to execute the other branch's code
  2. B. Create an additional Git Folder for the same repo with hotfix/schema-fix checked out, so both branches coexist in the workspace
  3. C. Run a %git checkout hotfix/schema-fix command as the first cell of the buggy notebook to load the teammate's version for that notebook only
  4. D. Ask the teammate to merge the fix into feature/dq-checks so that both changes can be tested in a single branch
