Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 222

When you configure a Layer 3 interface, what is one mandatory step?

Answer options

• A. Configure virtual routers to route the traffic for each Layer 3 interface.
• B. Configure Interface Management profiles, which need to be attached to each Layer 3 interface.
• C. Configure Security profiles, which need to be attached to each Layer 3 interface.
• D. Configure service routes to route the traffic for each Layer 3 interface.

Correct answer: A

Explanation

The correct answer is A because configuring virtual routers is necessary to enable routing for the Layer 3 interfaces. Options B and C refer to profiles that may enhance management and security but are not mandatory for Layer 3 configuration. Option D, while related to traffic management, does not address the required setup for Layer 3 interfaces specifically.
