PCNSA Device Management and Services Practice Question
Which TWO of the following are required when configuring a new virtual router on a Palo Alto Networks firewall?
⚠ Common exam trap
Test-takers frequently assume a dynamic routing protocol like OSPF is mandatory, but Palo Alto firewalls allow static routes as a perfectly valid and minimal routing configuration for a virtual router.

Correct answer & explanation
✓
Define at least one static route or enable a dynamic routing protocol
When configuring a new virtual router on a Palo Alto Networks firewall, you must assign at least one Layer 3 interface to it (Option E) so that the virtual router can participate in routing. Additionally, you must define at least one static route or enable a dynamic routing protocol (Option B) to provide a path for traffic; otherwise, the virtual router has no forwarding information and cannot route packets.
