The correct answer is to configure route leaking using route maps and the `set vrf` command under VRF1's routing process. This works because FortiGate’s multi-VRF implementation relies on route maps to selectively match prefixes from the source VRF, and the `set vrf` command then redistributes those matched routes into the destination VRF’s routing table, enabling controlled inter-VRF communication without needing VDOMs or static route workarounds. On the Fortinet NSE 7 Advanced Security exam, this question tests your understanding of policy-based route leaking versus simpler static methods—a common trap is assuming a static route or VDOM interlink is required, but the exam emphasizes that route maps with `set vrf` are the native, scalable approach for selective leaking between VRFs. A helpful memory tip: think “match and set”—match the routes with a route map, then set the target VRF to complete the leak.
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 has multiple VRFs. The administrator wants to leak a route from VRF1 to VRF2. Which configuration is required?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure route leaking using route maps and set vrf command under VRF1's routing process
Option A is correct because route leaking between VRFs on a FortiGate is achieved by configuring route maps with the `set vrf` command under the source VRF's routing process. This allows specific routes from VRF1 to be imported into VRF2, enabling controlled inter-VRF communication without requiring a VDOM or static route workaround.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Configure route leaking using route maps and set vrf command under VRF1's routing process
Why this is correct
Route leaking between VRFs is achieved by configuring route maps with set vrf and applying them under the routing process of the source VRF.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use the config router vrf-leak command to define leaking rules
Why it's wrong here
There is no such command; route leaking is done via route maps applied to the routing protocol.
✗
Enable inter-VRF routing on the VDOM
Why it's wrong here
Inter-VRF routing is not a simple toggle; it requires explicit route leaking configuration.
✗
Configure a static route in VRF2 pointing to the next-hop in VRF1 with a different administrative distance
Why it's wrong here
Static routes cannot directly reference a next-hop in another VRF without route leaking.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the FortiGate-specific route leaking method (route maps with `set vrf`) with generic Cisco-style VRF leaking commands or assume that a static route with a different administrative distance can bypass VRF isolation, which fails because VRFs are isolated at Layer 3 and require explicit route redistribution.

Detailed technical explanation
How to think about this question
Under the hood, FortiGate uses VRF (Virtual Routing and Forwarding) instances that maintain separate routing tables. Route leaking leverages route maps to match specific routes (e.g., by prefix or tag) and applies the `set vrf` action to copy them into the target VRF's routing table. This is commonly used in MPLS L3VPN environments where a service provider needs to leak a default route or specific customer routes between VRFs for centralized services like internet access or shared firewalls.

→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

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.
