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.

Catalog listing of the 5 preview questions for this quiz.

Question 1

A CMDB administrator must diagnose a payload that contains a dependent CI and a second payload item that lacks enough data for unique identification. The administrator wants to determine whether the dependent relationship was processed, whether the valid item was committed, and whether the unidentifiable item can be retried later. Select all statements that correctly describe the available evidence.

Answer choices

  • A. Identification Simulation can show input, IRE logs, and output for a simulated run without committing CMDB updates.

  • B. A partial item can be stored for potential later processing when it has a recoverable identification-related error.

  • C. An incomplete item is stored for logging and is not processed again.

  • D. A simulated output proves that the corresponding createOrUpdateCI API call already committed the CMDB changes.

  • E. A dependent CI can be generated without supplying information for its required dependency because IRE resolves all dependencies from the class name alone.

  • F. A payload with duplicate CIs is accepted by IRE and processed using the first matching CI.

Question 2

A Data Foundations advisor scope contains Server as a principal class. An administrator then changes the instance principal-class configuration outside the advisor by adding Database and removing Server. The advisor scope itself is not changed. When the administrator subsequently opens the Data Foundations advisor dashboard, what does the discrepancy between these two configurations cause the advisor to do?

Answer choices

  • A. The advisor replaces its stored scope with the current instance configuration without requiring the administrator to review the change.

  • B. The advisor compares its stored scope with the current instance principal-class configuration and notifies the administrator that the configurations are out of sync.

  • C. The advisor recalculates the principal classes from incident, problem, and change activity before determining whether the two configurations differ.

  • D. The advisor discards its stored scope because principal-class changes made outside the advisor invalidate the advisor configuration.

Question 3

An administrator wants principal-class filtering on Incident and Change records but finds that a task CI lookup includes too many non-principal CIs. Which statements correctly describe the control point? Select all that apply.

Answer choices

  • A. The com.snc.task.principal_class_filter property is a comma-separated list of task types.

  • B. Filtering is applied to the cmdb_ci field for task types listed in that property.

  • C. Removing a task type from the property can stop principal-class filtering for that task type without clearing the Principal Class designation on CI classes.

  • D. The property causes the Principal Class setting to derive automatically to every descendant class.

  • E. The property changes which CI classes are designated as principal in cmdb_class_info.

  • F. The default task-type list includes incident, problem, and change_request families.

Question 4

A dynamic CI group is being considered for a service instance and for a Technology management service. Which distinction determines whether service associations and impact analysis are expected?

Answer choices

  • A. Service-instance groups represent interdependent CIs, so service associations and impact analysis are expected; Technology management service groups can collect unrelated CIs for individual management.

  • B. Technology management service groups represent interdependent CIs, while service-instance groups collect unrelated CIs without impact analysis.

  • C. Both service types require identical service associations because every dynamic CI group propagates impact.

  • D. Neither service type uses service associations because dynamic CI groups are limited to task assignment.

Question 5

A CMDB Health design must limit duplicate-metric evaluation to Server and Network CIs, while preserving the relationship between duplicate results and IRE identification behavior. Which statements correctly describe the design? Select all that apply.

Answer choices

  • A. A health inclusion rule can limit the duplicate metric to Server and Network CIs.

  • B. Health inclusion rules can be defined per domain, but duplicate-metric health inclusion is supported in the global domain.

  • C. Identification inclusion rules can also affect which duplicate CIs appear because the dashboard uses IRE for duplicate identification.

  • D. Dot-walking is supported in duplicate-metric health inclusion rules and is required to identify descendant CIs.

  • E. A health inclusion rule on cmdb_ci can filter results for every descendant class without affecting any other health metric.

  • F. Duplicate-metric inclusion is controlled by Data Certification tasks rather than by health inclusion or identification inclusion rules.
