Messages may not be canceled by

Messages may not be canceled by

• A. a service message
• B. a direct reply from the sender
• C. an automatic system purge
• D. a confirmation from the recipient

Answer: (A)

Cancellation of a sent message is not accomplished through routine service communications. A service message is used to convey administrative or routing information about the message flow, not to revoke or nullify the original content. Because it lacks the authority and formality required for cancellation, it cannot cancel the message. The other mechanisms—like a direct reply from the sender, an automatic system purge, or a recipient’s confirmation—do not serve as official cancellation channels either, whereas a formal cancellation directive from the appropriate authority would be the proper means.
