Which practice supports maintaining complete, auditable records in CBM T6?

• A. Full audit trails and traceability to origin with controlled access.
• B. Regular backups only.
• C. Retention is optional.
• D. Data can be deleted after use.

Answer: (A)

Maintaining complete auditable records means creating a trustworthy, verifiable history of all data and actions: who did what, when, and where the data originated. Full audit trails capture every event with timestamps and user identities, so each change can be traced back to its source. When access to records is controlled, only authorized people can view or modify them, protecting the integrity of that history and preventing tampering.

This combination—comprehensive event logs, traceability to origin, and restricted access—provides the accountability and verifiability needed for audits, investigations, and regulatory compliance within CBM T6.

Regular backups are important for recovering data after a loss, but they don’t by themselves establish who changed what or ensure data can be audited. Optional retention creates gaps in the record, and deleting data after use destroys the evidence needed to verify the history.
