PCNSA Practice Question: Has multiple virtual routers on a single firewall
An organization has multiple virtual routers on a single firewall. Traffic between two virtual routers must be inspected by security policies. How should this be configured?
⚠ Common exam trap
Many candidates assume static routes or a global setting can enable inter-VR traffic with security inspection, but they overlook that PAN-OS requires explicit zone-based security rules to inspect traffic between virtual routers.

Correct answer & explanation
✓
Place each virtual router's interfaces into different zones, then create inter-zone security rules.
Inter-zone security rules are required to enforce security policies on traffic between different virtual routers. Each virtual router's interfaces must be assigned to distinct zones, and inter-zone rules inspect traffic crossing from one zone to another, ensuring the firewall applies security controls (e.g., App-ID, User-ID) to the traffic between the virtual routers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Place each virtual router's interfaces into different zones, then create inter-zone security rules.
Why this is correct
This ensures traffic is inspected by the security policy.
- ✗
Configure static routes between the virtual routers.
Why it's wrong here
Routes enable path but do not enforce security.
- ✗
Enable inter-virtual router routing under the global settings.
Why it's wrong here
This would bypass security policies.
- ✗
Apply security policies that match the virtual router as a source or destination.
Why it's wrong here
Security policies use zones, not virtual routers.
