Which protocol enables clients to manage emails on the server and retrieve messages, without downloading them permanently?

• A. IMAP
• B. POP3
• C. SMTP
• D. FTP

Answer: (A)

This question hinges on how email retrieval protocols differ in where messages live and how they’re accessed. The protocol that lets you manage mail directly on the server while you retrieve messages is designed so the messages stay on the server until you explicitly delete them, and actions you take (read/unread, move to folders, flag, delete) stay synchronized across devices. That behavior is what IMAP provides: it keeps a live view of your mailbox on the server, so you can organize and access messages from multiple devices without downloading them permanently. POP3, on the other hand, is geared toward downloading messages to the client; once downloaded, they’re typically removed from the server (unless you configure it to leave copies), which makes cross-device management harder. SMTP is used for sending messages, not retrieving. FTP is a general file transfer protocol and has nothing to do with email retrieval or mailbox management. So the protocol that matches the ability to manage emails on the server and retrieve messages without permanently downloading them is IMAP.
