About this MCQ
This Hard Computer Networks MCQ checks one syllabus fact.
The question is: “Select the correct name for: a number that divides an IP address into network and host portions.”
The accepted answer is B. Subnet mask. “Select the correct name for: a number that divides an IP address into network and host portions.” is answered by Subnet mask (option B). Option A (“Router”) does not match the stem; it is a near-miss used to catch incomplete recall of Subnet mask. Option C (“IP address”) does not match the stem; it is a near-miss used to catch incomplete recall of Subnet mask. Remaining alternatives (HTTP) fall outside the same rule and should be eliminated once Subnet mask 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.
