AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 225

What must be added to your web server configuration to view the true requesting IP address?

Answer options

• A. X-Actual-IP
• B. X-Forwarded-Proto
• C. X-Amzn-Trace-ID
• D. X-Forwarded-For

Correct answer: D

Explanation

The X-Forwarded-For header is specifically designed to carry the originating IP address of a client connecting to a web server through an HTTP proxy or load balancer. The other options do not serve this purpose; for instance, X-Actual-IP is not a standard header used for this functionality, while X-Forwarded-Proto and X-Amzn-Trace-ID relate to protocol and tracing, respectively.
