Palo Alto Networks Certified Network Security Administrator (PCNSA) — Question 203

What must exist in order for the firewall to route traffic between Layer 3 interfaces?

Answer options

• A. Virtual router
• B. Virtual wires
• C. Traffic Distribution profile
• D. VLANs

Correct answer: A

Explanation

A Virtual router is essential for a firewall to route traffic between Layer 3 interfaces, as it manages the forwarding of packets between different IP networks. The other options, such as Virtual wires, Traffic Distribution profiles, and VLANs, do not specifically facilitate routing at Layer 3, thus making them inadequate for this function.
