CompTIA Security+ (SY0-601) — Question 634

A security administrator needs to publish multiple application URLs that will run on different internal web servers but use only one external IP address. Which of the following is the best way for the administrator to achieve this goal?

Answer options

• A. Jump server
• B. Reverse proxy
• C. MAC filtering
• D. Source NAT

Correct answer: B

Explanation

The best solution for this scenario is a Reverse proxy, as it can route requests to multiple internal servers based on the URL while presenting a single external IP address to clients. A Jump server is not designed for this purpose, MAC filtering is related to device access control, and Source NAT primarily deals with address translation rather than URL routing.
