In CMDB governance, differentCMDB Data Manager policy typesserve different validation and enforcement purposes. When the objective is to allow an assigned individual toreview and update specific fields on a CI record, the correct policy type isCertification.

ACertification policycreates actionable tasks that require the assignee tovalidate and, if necessary, correct specific CI attributes, such as lifecycle status, support group, environment, or ownership. During certification, the user can directly update CI fields to bring the record into compliance with defined standards.

Attestation(Option C) only asks the user to confirm that a CIstill existsor is still valid; it does not require or enable attribute-level updates.Audit(Option A) is used for reporting and evidence collection, not remediation.Compliance(Option D) measures adherence to rules but does not itself generate editable remediation tasks.

Certification is therefore the primary mechanism used whenhuman validation and correctionof CI data is required—making it a cornerstone of CMDB data quality management.

Hence, the correct answer isB – Certification.
