The CMDB Data Manager uses Certification policies to generate tasks for assigned individuals or groups to review and update CI data. This process, known as data certification, ensures that CI information is accurate and current. The generated certification tasks explicitly allow the assignee to verify and correct fields on the CI record, fulfilling the requirement to enable updates.

A. Audit: While related to compliance, "Audit" is not a specific policy type within CMDB Data Manager that creates user tasks for updating fields.

C. Attestation: Attestation policies create tasks that ask users to simply confirm if the existing data is correct, rather than prompting them to update it.

D. Compliance: Compliance is a broader concept and a goal of data management, not a specific type of Data Manager policy that creates update tasks.
