The key difference lies in the scope and depth of verification. Attestation is a process to confirm that a CI still exists and that its ownership is correct. It is a high-level acknowledgement. Data Certification, conversely, is a more granular process that requires a user to validate the correctness of specific attributes (fields) on a CI record against a predefined template. It focuses on ensuring the accuracy of the data within the CI record itself, not just its existence.

A. This option incorrectly reverses the definitions of Attestation and Data Certification.

B. Both Attestation and Data Certification policies can be scheduled to run at regular intervals.

C. Both Attestation and Data Certification tasks can be assigned to either individual users or to groups.
