A Trusted Agent (TA) will maintain a transaction log for which of the following?

• A. Issued Tokens
• B. Recovered or tokens that are turned in
• C. Lost Tokens
• D. All of the above

Answer: (D)

Maintaining a transaction log relies on documenting every event that changes a token’s state. When tokens are issued, the log should record details such as the token identifier, who issued it, and the exact time. When tokens are recovered or turned in, the log should note the token, who turned it in, where it’s returned, and the timestamp. When tokens are lost, the log should capture the loss report, any investigation status, and any follow-up actions like replacements.

Having entries for all these events provides a complete, auditable trail of token activity. It supports accountability, traceability, and reconciliation, and it helps detect discrepancies or unusual activity quickly. That’s why the transaction log should cover issued tokens, recovered or turned-in tokens, and lost tokens—that all of the above are essential parts of a full record.
