Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 196

Which type of interface does a firewall use to forward decrypted traffic to a security chain for inspection?

Answer options

• A. Layer 3
• B. Layer 2
• C. Tap
• D. Decryption Mirror

Correct answer: A

Explanation

The correct answer is Layer 3 because firewalls typically operate at this layer to manage IP traffic, allowing decrypted data to be forwarded appropriately for inspection. Layer 2 pertains to data link functionalities and is not used for routing traffic to security chains. Tap and Decryption Mirror are specific methods for traffic monitoring but do not represent the interface type used for forwarding decrypted traffic.
