What is the difference betweenData CertificationandAttestationpolicies when managing a CI?

Within ServiceNow CMDB governance,AttestationandData Certificationserve distinct but complementary purposes. The key difference lies inwhat is being validated.

Attestationis focused onexistence and ownership confirmation. When a CI is attested, the assigned user or group is asked to confirm that the CIstill exists, is still relevant, and is still owned or managed by the appropriate team. No detailed attribute-level validation is required. This lightweight process is commonly used to prevent “ghost CIs” from lingering in the CMDB.

Data Certification, on the other hand, is more rigorous. It requires the certifier tovalidate specific attributesof the CI, such as lifecycle status, support group, environment, or service relationships. Certification ensuresdata correctness and completeness, which directly impacts CMDB Health scores and downstream processes like Change and Incident Management.

Options A, B, and C incorrectly describe these mechanisms or their assignment and scheduling capabilities. Both attestation and certification can be scheduled and assigned flexibly, but theirvalidation depthis what truly differentiates them.

Therefore,Option Dcorrectly describes the distinction: attestation confirms existence, while data certification validates CI attributes.
