Question

Which one of the following is a standard mail protocol used to receive emails from a remote server to a local email client?

1. A. SMI
2. B. POP3 (Correct answer)
3. C. SNMP
4. D. UDP

Correct Answer

Option B — POP3

Detailed Solution & Explanation

The correct answer is POP3.

Key Points

• POP3 (Post Office Protocol version 3) is a standard internet mail protocol used to retrieve email from a mail server to a local email client (such as Outlook or Thunderbird).
• POP3 downloads emails to your device and typically removes them from the server.
• It operates on port 110 (or 995 for SSL).
• SMTP is used for sending email; IMAP is used for accessing email while keeping it on the server; SNMP is a network management protocol; UDP is a transport-layer protocol -- none of these retrieve emails to a local client.
