CompTIA Network+ (N10-007) — Question 124

A server in a LAN was configured to act as a gateway between all company computers and an external network. Which of the following networking devices offers the ability to increase both performance and security?

Answer options

• A. Load balancer
• B. IDS
• C. Proxy server
• D. Wireless controller

Correct answer: C

Explanation

The correct answer is C, as a Proxy server can efficiently manage requests between clients and external servers, improving performance through caching and enhancing security by hiding internal IP addresses. The other options, while useful in their own right, do not provide the same combination of performance improvement and security features as a Proxy server.
