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 ServiceNow administrator wants to archive old CMDB history records that are older than 12 months to improve performance. Which approach should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the 'Archive Old Records' functionality in CMDB Workspace
Option C is correct because the CMDB Workspace provides a built-in 'Archive Old Records' functionality specifically designed to move old CMDB history records (e.g., from the `cmdb_ci_history` table) to an archive table, improving performance without data loss. This approach is supported by ServiceNow's recommended best practices for managing CMDB history data, as it preserves records for compliance while reducing the active table size.
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.
✗
Increase the 'CMDB History Pruning Frequency' property
Why it's wrong here
Pruning removes records permanently, not archives them.
✗
Manually delete rows from the 'cmdb_ci_history' table using SQL
Why it's wrong here
Direct database manipulation is not supported and can cause issues.
✓
Use the 'Archive Old Records' functionality in CMDB Workspace
Why this is correct
This is the designed feature to safely archive old history records.

✗
Run a scheduled report to export and then delete records
Why it's wrong here
No built-in export-delete mechanism; manual deletion would be needed.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'pruning' (which deletes records) with 'archiving' (which moves records to a separate table), leading them to choose Option A, or they incorrectly assume that manual SQL operations are acceptable in ServiceNow, which is a common anti-pattern tested on the CSA exam.
Detailed technical explanation
How to think about this question
The 'Archive Old Records' functionality in CMDB Workspace uses a dedicated archive table (e.g., `cmdb_ci_history_archive`) and a scheduled job to move records older than a configurable threshold, typically 12 months, based on the `sys_updated_on` field. Under the hood, it performs a batch move operation that respects database transaction boundaries, ensuring no data loss during the process, and the archived records remain queryable via the CMDB History Explorer. In real-world scenarios, this is critical for large enterprises with millions of CI history records, where direct table operations would cause performance degradation or lock contention.
KKey Concepts to Remember

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.
