SNOW-CSA Database Administration and CMDB Practice Question
This SNOW-CSA practice question tests your understanding of database administration and cmdb. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company uses Discovery to populate the CMDB. After a recent change, some CIs are incorrectly classified as 'Network Gear' instead of 'Server'. What is the most efficient way to correct the classification for these specific CIs?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Update the Discovery classification pattern and re-run Discovery on the affected IPs.
Option C is correct because Discovery classification patterns define how CIs are categorized based on probe results. Updating the pattern to correctly identify the affected CIs and re-running Discovery on their IPs ensures that the classification is corrected at the source, preventing future misclassification without manual intervention or data loss.
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.
✗
Delete the CIs and let Discovery recreate them.
Why it's wrong here
Deleting CIs is risky and not efficient; the same misclassification may occur if the pattern is not fixed.
✗
Manually change the 'Class' field on each CI.
Why it's wrong here
Manual changes are inefficient and do not fix the root cause.
✓
Update the Discovery classification pattern and re-run Discovery on the affected IPs.
Why this is correct
Correcting the pattern and re-running Discovery will reclassify the CIs correctly and prevent future issues.

✗
Run the 'Identify CI' probe again.
Why it's wrong here
If the classification pattern is wrong, re-running the probe will produce the same incorrect result.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think re-running the 'Identify CI' probe (Option D) will fix classification, but that probe only identifies CIs based on existing patterns and does not correct misclassification caused by a flawed pattern.
Detailed technical explanation
How to think about this question
Discovery uses classification patterns that include identification rules and conditions based on probe outputs (e.g., SNMP OIDs, WMI classes, SSH commands). When a pattern misclassifies a CI, updating the pattern's conditions (e.g., matching on a specific sysDescr OID or OS type) ensures that subsequent Discovery runs apply the correct CI class. Re-running Discovery on the affected IPs triggers the full identification and classification pipeline, including the updated pattern, without needing to delete or manually edit CIs.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
