A technician is configuring email on a mobile device. The user wants to be able to keep the original email on the server, organize it into folders, and synchronize the folders between the mobile device and the server. Which email protocol should the technician use?
- A.
MIME
- B.
POP3
- C.
SMTP
- D.
IMAP
Correct Answer
D. IMAPExplanation
IMAP (Internet Message Access Protocol) is the correct email protocol to use in this scenario. IMAP allows the user to keep the original email on the server, organize it into folders, and synchronize these folders between the mobile device and the server. This means that any changes made on the mobile device, such as moving emails to folders, will also be reflected on the server. Unlike POP3 (Post Office Protocol version 3), which downloads emails to the device and typically does not synchronize folders, IMAP provides a more robust and synchronized email experience across multiple devices. SMTP (Simple Mail Transfer Protocol) is used for sending emails, while MIME (Multipurpose Internet Mail Extensions) is a standard for encoding email attachments.Rate this question:
