Which format line will be used in Code Dress messages when the called station is required to deliver or refile the messages without decrypting it?

• A. 4
• B. 2
• C. 3
• D. 1

Answer: (A)

The key idea is how a secure message is handled when it must pass through hops without exposing its content. In Code Dress messages, the format line that directs the called station to deliver or refile the message without decrypting it is used precisely for this situation. It tells intermediate stations to treat the message as ciphertext and forward it unchanged, so only the final recipient, who has the decryption keys, can read it. This preserves confidentiality across the routing path. Other format lines would imply decrypting at an intermediate hop or altering the message in some way, which would expose the contents or break the intended handling. By choosing the line that mandates not decrypting, the system maintains end-to-end security while still ensuring the message reaches its destination.
