NSE7 Advanced Networking and SD-WAN Practice Question
A FortiGate is configured with two static routes to the same destination 0.0.0.0/0 with equal distance but different priorities. The priority values are 10 and 20. Which route will be used for traffic matching the default route?
⚠ Common exam trap
Watch out — candidates often confuse priority with administrative distance or assume higher priority is better, but FortiGate uses lower priority values as more preferred, opposite to the common intuition from other vendors like Cisco where a lower metric is better but the term 'priority' can be misleading.

Correct answer & explanation
✓
The route with priority 10 will be used.
In FortiGate, when multiple static routes have the same distance (administrative distance) to the same destination, the route with the lowest priority value is selected. Priority is a FortiGate-specific metric that breaks ties among routes with equal distance. Since priority 10 is lower than 20, the route with priority 10 will be installed in the routing table and used for traffic matching 0.0.0.0/0.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The route with priority 20 will be used.
Why it's wrong here
Higher priority number is lower preference.
- ✗
The route with lower distance will be used.
Why it's wrong here
Distance is equal, so not a factor.
- ✓
The route with priority 10 will be used.
Why this is correct
Priority 10 is higher preference than 20.
- ✗
Both routes will be used for load balancing.
Why it's wrong here
Equal distance but different priority; only the higher priority route is used.
