About this MCQ
This Easy Computer Networks MCQ checks one syllabus fact.
The question is: “The concept in which a protocol used for sending email messages between servers is best known as which of these terms?”
The accepted answer is A. SMTP. “The concept in which a protocol used for sending email messages between servers is best known as which of these terms” is answered by SMTP (option A). Option B (“Network hub”) does not match the stem; it is a near-miss used to catch incomplete recall of SMTP. Option C (“FTP”) does not match the stem; it is a near-miss used to catch incomplete recall of SMTP. Remaining alternatives (Packet switching) fall outside the same rule and should be eliminated once SMTP is identified. Computer Networks questions of this type reward precise definitions rather than approximate associations. Computer Networks recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
