- A
The PBR rule uses a route map that references an incorrect prefix list.
Why wrong: While possible, the most common mistake is applying PBR on the wrong interface or direction.
- B
The PBR rule is applied on the wrong interface or direction.
PBR must be applied to the ingress interface where traffic arrives. If applied to the wrong interface or direction, traffic will not match.
- C
The PBR rule has a higher priority than the SD-WAN rule, but the traffic is hitting the SD-WAN rule first because of firewall policy order.
Why wrong: PBR is evaluated before firewall policies, so order of firewall policies does not affect PBR.
- D
The traffic is generated locally from the FortiGate and PBR does not affect locally generated traffic.
Why wrong: PBR can affect locally generated traffic if configured appropriately; the question implies transit traffic.
Quick Answer
The answer is that the PBR rule is applied on the wrong interface or direction. Policy-based routing on FortiGate is evaluated only on the ingress interface where traffic first enters the device, meaning the rule must be attached to the interface receiving the traffic and configured for the correct incoming direction. If an administrator mistakenly applies the PBR policy to the egress interface or selects the wrong direction, the traffic will never be matched, even if all other conditions like source, destination, and protocol are correct. On the Fortinet NSE 7 Advanced Security NSE7 exam, this is a common trap designed to test your understanding that PBR operates at the point of entry, not exit, and it often appears alongside questions about route lookup order or policy routing versus static routing. A reliable memory tip is “PBR is for Packets Before Routing”—the rule must catch the packet as it arrives, not after it has already been routed out.
NSE7 Advanced Networking and SD-WAN Practice Question
This NSE7 practice question tests your understanding of advanced networking and sd-wan. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A FortiGate is configured with policy-based routing (PBR) to route certain traffic through a specific next hop. However, some traffic that should match the PBR rule is not being affected. What is a likely reason?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The PBR rule is applied on the wrong interface or direction.
Policy-based routing is applied on the ingress interface. If the administrator applied it to the egress interface or forgot to apply it to the correct ingress interface, the traffic will not match.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 PBR rule uses a route map that references an incorrect prefix list.
Why it's wrong here
While possible, the most common mistake is applying PBR on the wrong interface or direction.
- ✓
The PBR rule is applied on the wrong interface or direction.
Why this is correct
PBR must be applied to the ingress interface where traffic arrives. If applied to the wrong interface or direction, traffic will not match.

- ✗
The PBR rule has a higher priority than the SD-WAN rule, but the traffic is hitting the SD-WAN rule first because of firewall policy order.
Why it's wrong here
PBR is evaluated before firewall policies, so order of firewall policies does not affect PBR.
- ✗
The traffic is generated locally from the FortiGate and PBR does not affect locally generated traffic.
Why it's wrong here
PBR can affect locally generated traffic if configured appropriately; the question implies transit traffic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the NSE7 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles
2 more ways this is tested on NSE7
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A FortiGate is configured with policy-based routing to force traffic from subnet 10.0.1.0/24 to go through a WAN interface. The administrator notices that traffic from 10.0.1.0/24 is still using the default route. Which debug command can confirm if the policy-based routing is being applied?
medium- A.diagnose debug routing ip-probe 10.0.1.1 8.8.8.8
- ✓ B.diagnose debug flow policy-based-route
- C.diagnose debug enable && diagnose debug router policy
- D.get router info policy-based-route
Variation 2. You want to use policy-based routing (PBR) to send traffic from a specific subnet to a different next-hop than the default route. Which configuration is required?
medium- ✓ A.Configure a route map under 'config router policy'
- B.Create a firewall policy with 'set policy-based-route enable'
- C.Enable 'set pbr-enforce-symmetric' on the interface
- D.Configure a prefix list and apply to the static route
Why A: Policy-based routing is configured under 'config router policy' with source/destination addresses and a set-next-hop action.
