IPA IP 2021 Question 84
A question IPA Japan published in 令和3年度 ITパスポート試験 公開問題 問84, translated into English. ITPEC is based on the same exams.
Mail software has been newly installed on a PC. Which of the following corresponds to a protocol that needs to be set up at that time?
Explanation
POP3 — the protocol mail software uses to receive e-mails from the mail server, so its server has to be set when the software is installed.
When mail software is set up, it must be told which servers to use: the receiving server (POP3, or IMAP4) with the account name and password, and the sending server (SMTP). POP3 (Post Office Protocol version 3) downloads the messages stored in the user's mailbox on the mail server to the PC. Of the options, it is the only one that is a mail protocol configured in the mail software.
Answer (d)
Why not others:
- •(a) DNS — translates domain names into IP addresses; the PC's network settings or DHCP provide the DNS server, not the mail software
- •(b) FTP — a protocol for transferring files between computers, not used for e-mail
- •(c) MIME — a standard for attaching files and non-ASCII text to e-mail; the mail software handles it by itself, with nothing to set
Key rule: Mail software is set up with its receiving server (POP3 or IMAP4) and its sending server (SMTP); DNS, FTP and MIME are not configured there.
