CIS-DF Questions Bank

The Correctness scorecard evaluates whether CI data accurately represents the real environment. It includes the Duplicate , Orphan , and Staleness metrics.

Duplicate identifies cases where the same real-world configuration item is represented by multiple CMDB records. Orphan identifies CIs that lack expected relationships or supporting context. Staleness identifies records that have not been updated within the configured period and may no longer represent active infrastructure.

The other choices belong to different CMDB Health KPIs. Audit belongs to Compliance because it evaluates whether CI values satisfy defined standards or desired-state conditions. Required and Recommended belong to Completeness because they measure whether mandatory and useful attributes are populated.

Therefore, Duplicate, Orphan, and Staleness are the metrics shown under Correctness.

Principal Classes are a key CMDB configuration concept used to control which CI classes are selectable in reference fields across ITSM processes. This helps reduce noise, prevent incorrect CI selection, and improve data quality.

In ServiceNow, Principal Classes are designated within the CI Class Manager. This tool allows CMDB administrators to manage the CI class hierarchy, define ownership, and explicitly mark classes as principal. Once a class is marked as principal, its CIs become available in CI reference fields such as those on Incident, Change, and Problem forms.

Option A (CMDB Workspace) provides operational and analytical views but does not control schema-level class behavior. Option C (System Properties) does not manage class designation. Option D (CMDB Data Manager) governs lifecycle and data quality policies, not reference field behavior.

By configuring Principal Classes in the CI Class Manager, organizations ensure that only relevant, high-value CI classes are exposed to end users, aligning with Data Foundations best practices.

Therefore, the correct answer is B – CI Class Manager.

The Management tab provides the direct administrative path to CMDB Data Manager. Under Management tools, the administrator can open Data Manager to create, edit, review, publish, and track lifecycle policies. ServiceNow’s documented procedure for creating a policy begins by selecting CMDB Workspace > Management > Data Manager > Policies .

The Home tab also provides access through its Quick Links section. The Data Manager quick link opens the same policy-management capability and allows authorized administrators to create, review, publish, and monitor policies.

The My Work tab is used primarily to review and process tasks generated after policies run; it is not the policy-configuration entry point. CMDB 360 is used for multisource data visibility, while Insights focuses on analytical and adoption information. Therefore, the two tabs providing access are Management and Home.

Enabling Multisource CMDB makes the CMDB 360 experience available in CMDB Workspace. CMDB 360 provides visibility into the different discovery and integration sources contributing information to a CI. Administrators can compare source-level attribute values, identify data gaps and conflicts, and investigate how reconciliation determines the final value stored on the CI.

The Home tab provides general workspace navigation and summary information. The Management tab contains administrative capabilities such as CMDB Data Manager policies. The Insights tab provides adoption, health, and analytical information, but it is not the primary Multisource CMDB work area.

The study guide specifically states that CMDB 360 saved queries are viewed and created through the Saved Queries area on the CMDB 360 tab. It also explains that Multisource CMDB retains source contributions and supports analysis of differing or missing values across sources. Therefore, enabling the feature populates the CMDB 360 tab.
