Last updated May 15, 2026
Correct Answer:
Option B —
POP3
Understanding the Protocols
POP3 (Post Office Protocol): Think of this like a physical post office. You go in, pick up your mail, and take it home. Once you have it, it's no longer at the post office.
IMAP (Internet Message Access Protocol): This is the main alternative to POP3. It syncs your mail across devices, meaning the mail stays on the server so you can see the same inbox on your phone and your laptop.
Why the other options are incorrect:
A) SMI (Structure of Management Information): Used in network management to define the objects managed by SNMP.
C) SNMP (Simple Network Management Protocol): Used for collecting and organizing information about managed devices on IP networks (like routers, switches, and printers).
D) UDP (User Datagram Protocol): A communications protocol used across the internet for especially time-sensitive transmissions such as video playback or DNS lookups. It is a "transport layer" protocol, not an email protocol.
