Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 430

An organization conducts research on the benefits of leveraging the Web Proxy feature of PAN-OS 11.0.

What are two benefits of using an explicit proxy method versus a transparent proxy method? (Choose two.)

Answer options

• A. No client configuration is required for explicit proxy, which simplifies the deployment complexity.
• B. Explicit proxy supports interception of traffic using non-standard HTTPS ports.
• C. It supports the X-Authenticated-User (XAU) header, which contains the authenticated username in the outgoing request.
• D. Explicit proxy allows for easier troubleshooting, since the client browser is aware of the existence of the proxy.

Correct answer: C, D

Explanation

The correct answers are C and D because the explicit proxy method can utilize the X-Authenticated-User (XAU) header, allowing for better user identification, and it provides clearer troubleshooting since the client is aware of the proxy's existence. Options A and B are incorrect because explicit proxies do require client configuration and the ability to intercept non-standard HTTPS ports is not a unique benefit of explicit proxies.
