Configuration Management Database Questions
CI Class Manager, CMDB Health Dashboard, tables, reclassification, and identification and reconciliation rules.
About Configuration Management Database
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 This Matters for Your 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
Master the CMDB table structure (cmdb_ci and extensions), CI Class Manager for class management, CMDB Health Dashboard metrics (Completeness, Compliance, Correctness), and how identification rules prevent duplicates.
Exam Tips
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.
