A Trusted Agent handles which of the following credentials?

• A. Digital signature credentials
• B. Passport copies
• C. Email addresses
• D. URLs

Answer: (A)

This item tests what kinds of credentials a Trusted Agent is responsible for handling. A Trusted Agent manages digital signature credentials because these cryptographic materials prove identity and authorize actions in digital systems. That includes private keys used to generate signatures and the certificates or public keys used by others to verify them. The Trusted Agent safeguards these keys, stores them securely (often in hardware security modules or secure vaults), and handles issuing, renewing, and revoking certificates to keep signing trust intact.

Passport copies are personal documents and not credentials used for cryptographic signing. Email addresses are identifiers that may be used in identity systems, but they aren’t the cryptographic credentials a Trusted Agent primarily handles. URLs are addresses of resources and also not credentials for signing or authentication.
