What is the name for a technique that maps multiple private IP addresses to a single public IP address?
Difficulty: Hard
About this MCQ
This Hard Computer Networks MCQ checks one syllabus fact.
The question is: “What is the name for a technique that maps multiple private IP addresses to a single public IP address?”
The accepted answer is A. NAT. NAT is the fact required by “What is the name for a technique that maps multiple private IP addresses to a single public IP address” (option A). Option B (“Bandwidth”) does not match the stem; it is a near-miss used to catch incomplete recall of NAT. Option C (“UDP”) does not match the stem; it is a near-miss used to catch incomplete recall of NAT. Remaining alternatives (DNS) fall outside the same rule and should be eliminated once NAT 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.
