CMDB Data Manager supports multiple governance policy types because CMDB lifecycle management is broader than simply deleting or certifying records. The complete set represented here is Retire, Archive, Attestation, Certification, and Delete. Retire policies support lifecycle transition of CIs that should no longer be active. Archive policies remove records from active operational use while preserving them according to retention requirements. Delete policies permanently remove records when they no longer need to be retained. Attestation policies validate that a CI still exists or is still relevant. Certification policies require users to validate and potentially correct specific CI attribute values. Options B, C, and D are incomplete because each omits at least one major CMDB Data Manager policy type. Option A is therefore the best answer because it includes both lifecycle/removal policy types and validation-focused policy types.
