Overview
The Ingest domain covers how data gets into the CMDB — from the Identification and Reconciliation Engine (IRE) that prevents duplicates, to Service Graph Connectors that pull data from external sources like AWS, Azure, and Dynatrace. Understanding the full data pipeline is critical.
Why It Matters for the Exam
Ingest accounts for 19% of the CIS-DF exam. The IRE is central to CMDB data integrity — you must understand identification rules, reconciliation rules, and how CI reclassification works. Service Graph Connectors and import sets are the primary methods for populating the CMDB.
Key Concepts to Master
💡 Exam Tips & Strategy
Pay attention to IRE properties and their defaults (e.g., skip_duplicates threshold of 5). Know the difference between Regular and Lookup identifier entry types. Understand how Service Graph Connectors use IRE for data insertion.
