Databricks-DE-Pro Debugging and Deploying Practice Question
A data engineer is using Databricks Repos to manage a project. They need to ensure that the production job always uses the code from the 'main' branch, even if developers push changes to other branches. Which Git reference should be used in the job configuration to achieve this?
⚠ Common exam trap
The trap here is assuming that a tag or commit hash provides the same automatic updates as a branch, when in fact they are static references.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The branch name 'main'
In Databricks Repos, job configurations can reference a Git branch, tag, or commit. To always use the latest code from the 'main' branch, the job should be configured with the branch name 'main'. At runtime, Databricks checks out the latest commit on that branch. Using a commit hash or tag would pin to a specific version and not automatically update, which is unsuitable for continuous deployment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The branch name 'main'
Why this is correct
Specifying the branch name 'main' in the job configuration ensures that the job checks out the latest commit on that branch at runtime. This means any new commits pushed to 'main' will be used in subsequent job runs, satisfying the requirement to always use production code from 'main'.
- ✗
A specific commit hash
Why it's wrong here
Using a specific commit hash pins the job to an exact version, but it does not automatically update when the 'main' branch changes. The job would run stale code unless the hash is manually updated. This does not meet the requirement of always using the latest code from 'main'.
- ✗
The remote URL of the repository
Why it's wrong here
The remote URL alone does not specify a branch or commit; it only identifies the repository. Without a branch or commit, the job cannot determine which code to use. This option is incomplete and would likely cause an error or default to the default branch, which may not be 'main'.
- ✗
A tag named 'production'
Why it's wrong here
Tags are static references to specific commits. Using a tag would not automatically pick up new changes to 'main' unless the tag is moved, which is not standard practice. This would require manual intervention to update the tag, failing the requirement for automatic updates.
