Configuration Management Database
ServiceNow CIS-Discovery Study Guide
Overview
Discovery populates the CMDB with configuration items (CIs) and their relationships. Understanding CI class hierarchy, identification rules, reconciliation, and CMDB health monitoring is essential for successful Discovery implementation.
Why It Matters for the Exam
CMDB Integration is 15% of the CIS-Discovery exam. Questions focus on CI Class Manager, CMDB Health Dashboard KPIs, identification and reconciliation rules, data source precedence, and de-duplication.
Key Concepts to Master
💡 Exam Tips & Strategy
Know the CMDB Health KPIs: Completeness (mandatory fields), Compliance (audits), Correctness (orphan, staleness, duplicates). Understand how CI identifiers use criterion attributes. Remember that Discovery doesn't populate Assets directly—it creates CIs which trigger asset creation via model categories.
