Question

An engineer is configuring a firewall with three interfaces:

  • MGT connects to a switch with internet access.
  • Ethernet1/1 connects to an edge router.
  • Ethernet1/2 connects to a virtualization network.

The engineer needs to configure dynamic updates to use a dataplane interface for internet traffic.
What should be configured in Setup > Services > Service Route Configuration to allow this traffic?

A. Set DNS and Palo Alto Networks Services to use the MGT source interface.
B. Set DNS and Palo Alto Networks Services to use the ethernet1/1 source interface.
C. Set DNS and Palo Alto Networks Services to use the ethernet1/2 source interface.
D. Set DDNS and Palo Alto Networks Services to use the MGT source interface.

Answer

B. Set DNS and Palo Alto Networks Services to use the ethernet1/1 source interface.

Explanation

To allow dynamic updates to use a dataplane interface for internet traffic in the firewall configuration described, the engineer should select option:

B. Set DNS and Palo Alto Networks Services to use the ethernet1/1 source interface.

  • The Ethernet1/1 interface is the one connecting to the edge router, which typically handles internet traffic.
  • Configuring the DNS and Palo Alto Networks services to use this interface ensures that dynamic updates, which include services such as threat prevention and URL filtering, utilize the ethernet1/1 interface for internet-bound traffic.
  • This ensures that the traffic for dynamic updates goes through the appropriate interface, aligning with the requirement to use a dataplane interface for internet traffic.
