NSE7 Advanced Networking and SD-WAN Practice Question
An administrator wants to segment traffic between two departments (Engineering and Finance) using the same FortiGate. Each department must have its own routing table with overlapping IP addresses. Which feature should be enabled to achieve this without creating separate VDOMs?
⚠ Common exam trap
Test-takers frequently confuse VRF with VDOMs, assuming that only VDOMs can provide routing isolation, but VRF achieves the same within a single VDOM without the overhead of separate management domains.
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
✓
VRF
VRF (Virtual Routing and Forwarding) allows a single FortiGate to maintain multiple independent routing tables, enabling overlapping IP address spaces for different departments without requiring separate VDOMs. Each VRF instance isolates routing decisions, forwarding tables, and interfaces, meeting the segmentation requirement while preserving a unified management plane.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
VRF
Why this is correct
VRF provides separate routing tables within a VDOM, allowing overlapping IP addresses.
- ✗
Policy-based routing
Why it's wrong here
PBR can steer traffic but not maintain separate routing tables.
- ✗
Virtual IP (VIP)
Why it's wrong here
VIP is for NAT destination mapping, not routing segmentation.
- ✗
Multiple VDOMs
Why it's wrong here
VDOMs would also work but are more resource-intensive and require separate management.
