What is the importance of an audit trail in CPPA transactions?

• A. It stores medical records.
• B. It is optional and rarely used.
• C. It replaces the need for error logs.
• D. It provides traceability and supports regulatory compliance and error resolution.

Answer: (D)

An audit trail in CPPA transactions records who did what, when, and what data was affected. This creates traceability so you can reconstruct events, hold individuals accountable, and detect any unauthorized activity. It also supports regulatory compliance by providing verifiable evidence of how data was accessed or changed, and it helps with error resolution by letting you identify exactly where a mistake occurred and who approved the action. The audit trail does not store the actual medical records themselves; it logs the actions taken. It isn’t optional or rarely used—it's a fundamental part of maintaining data integrity and security, working alongside other logs and controls to ensure accountability and smooth investigation of issues.
