NSE4 System and Network Administration Practice Question
An administrator configures a policy route to send all traffic from subnet 172.16.1.0/24 to a specific next-hop 10.0.0.2. However, the traffic is still using the default route. What could be the reason?
⚠ Common exam trap
A common mix-up: candidates assume policy routes automatically override static routes, but FortiGate uses a priority-based selection where the default route's implicit priority of 0 can supersede a policy route with a higher priority value.

Correct answer & explanation
✓
The policy route has a lower priority than the default route.
Policy routes in FortiGate are evaluated based on their priority value, where a lower number indicates higher priority. If the policy route has a higher priority value (e.g., 10) than the default route (which is implicitly 0), the default route will be preferred. The administrator must ensure the policy route's priority is lower than the default route's priority to override it.
