CompTIA Network+ (N10-009) — Question 42

Which of the following best describes what an organization would use port address translation for?

Answer options

• A. VLANs on the perimeter
• B. Public address on the perimeter router
• C. Non-routable address on the perimeter router
• D. Servers on the perimeter

Correct answer: C

Explanation

Port address translation is primarily used to allow internal non-routable addresses to communicate with external networks by translating these addresses to a routable address on the perimeter router. Options A, B, and D do not pertain directly to the function of port address translation, which specifically relates to handling non-routable addresses.
