CompTIA Network+ (N10-009) — Question 287

A firewall administrator is mapping a server's internal IP address to an external IP address for public use. Which of the following is the name of this function?

Answer options

• A. NAT
• B. VIP
• C. PAT
• D. BGP

Correct answer: A

Explanation

NAT, or Network Address Translation, is the process that allows for the mapping of an internal IP address to an external one, enabling public access to a server. The other options, such as VIP (Virtual IP), PAT (Port Address Translation), and BGP (Border Gateway Protocol), serve different functions in networking and do not specifically refer to the mapping of IP addresses as described in the question.
