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
✓
Store configuration backups in a version-controlled repository before each change
Storing configuration backups in a version-controlled repository before each change ensures that a known good state is available for rollback, even if subsequent changes occur.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a single source of truth like NetBox
Why it's wrong here
NetBox tracks intended state, not operational configuration snapshots.
- ✓
Store configuration backups in a version-controlled repository before each change
Why this is correct
This ensures a recoverable snapshot exists for any rollback.

Use the 'check mode' only
Why it's wrong here
Check mode does not create backups.
- ✗
Disable rollback pipelines
Why it's wrong here
Disabling rollback is not a best practice.
