In ServiceNow, the Compliance dimension of the CMDB Health Dashboard is driven by Data Certification. To surface meaningful compliance results—such as identifying servers that are not on the latest patch—the platform requires a combination of Certification Policies, Data Filters, and Scheduled Jobs.

Certification Policies define what data must be validated and which attributes are subject to compliance checks (for example, patch level, OS version, or last update date). Data Filters scope the population—such as server classes only—ensuring the compliance evaluation targets the correct CIs. Scheduled Jobs automate when certifications run, keeping compliance scores current and reflective of the latest state.

Options A and C are incorrect because audits and stale/orphan/duplicate checks relate to other health dimensions (correctness and completeness), not compliance. Option B focuses on service modeling and group alignment, which does not directly drive compliance scoring for patch currency.

Therefore, configuring Certification Policies, Data Filters, and Scheduled Jobs is required to accurately measure and display patch compliance on the CMDB Health Dashboard.
