Certification Summary

The ServiceNow CIS-Data Foundations certification is for CMDB admins and platform architects who spend their shifts fixing discovery duplicates and fighting with teams over broken CI classes. You sit this exam if you are the person the bridge call leader pings when the CMDB health dashboard stays red and the identification engine fails to reconcile incoming hardware data.

Expect to spend your time on Govern at 35 percent, which covers the reconciliation rules and data audits that stop the CMDB from becoming a junk drawer. Ingest and Insight make up 39 percent of the exam, focusing on how data enters the system and how you report on its health, while Configure and CSDM Fundamentals cover the remaining 26 percent. You will see questions about setting up identification and reconciliation rules for specific CI classes and mapping business services to infrastructure using the common service data model.
