SNOW-CSA Database Administration and CMDB Practice Question
Exhibit
A CMDB Health Dashboard shows a metric: 'Completeness: 85%', with a note: 'Fields with missing data: asset_tag, model_id, cost_center'.
Refer to the exhibit. What action should the administrator take to improve the completeness score?
⚠ Common exam trap
A common mix-up: candidates confuse adjusting the CMDB Health weight (a scoring mechanism) with actually fixing data quality issues, leading them to select option D instead of recognizing that a data certification policy directly enforces data population.

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
✓
Configure a data certification policy with required fields.
A data certification policy in ServiceNow allows administrators to define required fields for CI classes. When a data certification policy is configured with required fields, the system automatically validates that those fields are populated during certification runs, directly improving the completeness score by ensuring critical data is present. This is a proactive, automated approach that aligns with CMDB Health best practices.
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 scheduled job to populate common fields with default values.
Why it's wrong here
Default values may not be accurate and could create data quality issues.
- ✗
Manually edit each CI that has missing fields.
Why it's wrong here
Manual editing does not scale and is not sustainable.
- ✓
Configure a data certification policy with required fields.
Why this is correct
Data certification enforces completeness by requiring those fields during periodic review.
- ✗
Increase the CMDB Health weight for completeness.
Why it's wrong here
Changing the weight only affects scoring, not data quality.
