Question

Consider the SMTP. Which of the following statements is FALSE?

Group of answer choices
a) SMTP messages must be in 7-bit ASCII
b) SMTP uses persistent connections
c) SMTP is used to transfer messages from a mail

Answer 1

The FALSE statement regarding SMTP is option b) "SMTP uses persistent connections."

Step-by-step explanation:

SMTP (Simple Mail Transfer Protocol) is a text-based protocol used for the transmission of electronic mail. Contrary to option b, SMTP typically uses transient, not persistent, connections. In SMTP, a connection is established, and the mail transfer occurs. Once the transfer is complete, the connection is terminated. This is in contrast to persistent connections, which remain open for multiple transactions. Option a correctly states that SMTP messages must be in 7-bit ASCII, adhering to its character encoding requirements. Option c accurately describes SMTP's purpose of transferring messages from a mail client to a server or between mail servers.

Option B is the answer, as SMTP commonly employs transient connections rather than persistent ones.
