Which system preserves messages for later retrieval by authorized personnel?

• A. Fax machine
• B. Email
• C. Voice mail
• D. Calendar

Answer: (C)

When a system is meant to keep messages so they can be retrieved later by someone with permission, the key idea is stored, retrievable messaging with access control. Voice mail fits this role best: it records and stores a caller’s message in the recipient’s mailbox, and it remains there until the authorized user signs in and listens to it. The message is preserved in the voicemail system with a defined retention period and security like a PIN, so someone authorized can access it later. A fax machine is mainly for sending documents and doesn’t serve as a persistent, account-based message store for later retrieval by an authorized person. Email does preserve messages, but it’s primarily a general communication channel rather than a dedicated, permission-controlled message mailbox. A calendar stores events, not messages.
