CompTIA Network+ (N10-008) — Question 315

A help desk engineer needs to configure two servers to have the same public IP addresses. Which of the following technologies should the engineer use?

Answer options

• A. NAT
• B. VIP
• C. DNS caching
• D. RFC 1918
• E. SDWAN

Correct answer: A

Explanation

NAT (Network Address Translation) allows multiple devices on a local network to be mapped to a single public IP address, which is essential for the two servers to share the same public IP. VIP (Virtual IP) could also be relevant but is typically used in load balancing scenarios. The other options, such as DNS caching and RFC 1918, do not facilitate the sharing of public IP addresses, and SDWAN is more about optimizing wide area network connections.
