About this MCQ
This Easy Computer Networks MCQ checks one syllabus fact.
The question is: “The concept in which a network security device or software that monitors and filters incoming and outgoing traffic based on rules is best known as which of these terms?”
The accepted answer is B. Firewall. “The concept in which a network security device or software that monitors and filters incoming and outgoing traffic based on rules is best known as which of these terms” is answered by Firewall (option B). Option A (“Router”) does not match the stem; it is a near-miss used to catch incomplete recall of Firewall. Option C (“VPN”) does not match the stem; it is a near-miss used to catch incomplete recall of Firewall. Remaining alternatives (IP address) fall outside the same rule and should be eliminated once Firewall 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.
