SNOW-CSA Database Administration and CMDB Practice Question
Which THREE of the following are best practices for CMDB data maintenance? (Choose exactly 3.)
⚠ Common exam trap
ServiceNow often tests the misconception that disabling discovery is a valid maintenance strategy, when in fact it is the opposite; the trap here is confusing 'maintenance' with 'preventing change' rather than 'ensuring data accuracy through automation'.

Correct answer & explanation
✓
Scheduled reconciliation to identify and merge duplicates
Scheduled reconciliation is a core CMDB best practice that uses identification rules to automatically detect and merge duplicate CIs, ensuring a single source of truth. This process relies on the CMDB's reconciliation engine, which compares CI attributes against defined identification and reconciliation rules to resolve conflicts without manual intervention.
