SNOW-CSA Database Administration and CMDB Practice Question
This SNOW-CSA practice question tests your understanding of database administration and cmdb. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator is troubleshooting why a CMDB CI's last discovered date is not updating after a successful discovery run. The CI is in a valid state and the discovery schedule runs. What could be the cause?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The reconciliation rule is set to 'Manual' and the discovered data conflicts with existing data.
Option C is correct because when a reconciliation rule is set to 'Manual', the CMDB will not automatically update CI attributes with discovered data if there is a conflict with existing data. The CI remains in its last discovered state until a manual reconciliation is performed, even if the discovery run succeeds and the CI is valid.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 CMDB identification rule has a condition that excludes this CI from updates.
Why it's wrong here
If the CI is discovered, the condition likely allows matching.
✗
The discovery source is set to 'ServiceNow' but the CI was created manually.
Why it's wrong here
Discovery source does not affect the update; manual CIs can still be updated.
✓
The reconciliation rule is set to 'Manual' and the discovered data conflicts with existing data.
Why this is correct
Manual reconciliation prevents automatic updates when conflicts arise, so the date stays unchanged.

✗
The CI is a parent class and child class discovery is updating child records.
Why it's wrong here
Parent CIs can still be updated directly by discovery.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse reconciliation rules with identification rules or assume that a successful discovery run always updates the last discovered date, overlooking the impact of manual reconciliation settings on attribute updates.
Detailed technical explanation
How to think about this question
Reconciliation rules in ServiceNow control how discovered data is merged with existing CI data. When set to 'Manual', any conflict between discovered attributes and existing values requires an administrator to manually approve the update, which means the last discovered date field (sys_updated_on) is not automatically refreshed. This is distinct from identification rules, which handle CI matching, and discovery schedules, which control when discovery runs.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SNOW-CSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
