NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator wants to isolate tenant traffic in a single FortiGate by creating separate virtual firewalls with independent routing tables, administrators, and policies. Which feature should the administrator use?
⚠ Common exam trap
Many candidates confuse VLANs (Layer 2 segmentation) with VDOMs (Layer 3+ virtual firewall isolation), leading candidates to pick VLANs because they think network segmentation alone achieves tenant isolation, but VLANs lack independent routing tables and administrative 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
✓
Virtual Domains (VDOMs)
VDOMs (Virtual Domains) are the correct feature because they partition a single FortiGate into multiple independent virtual firewalls, each with its own routing table, administrator access, and security policies. This allows complete tenant isolation within one physical appliance, meeting the administrator's requirement for separate virtual firewalls with independent routing, administration, and policy control.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Virtual Domains (VDOMs)
Why this is correct
Correct.
- ✗
Policy-based routing (PBR)
Why it's wrong here
PBR controls route selection, not tenant isolation.
- ✗
Virtual Router Redundancy Protocol (VRRP)
Why it's wrong here
VRRP provides high availability, not logical separation.
- ✗
Virtual LANs (VLANs)
Why it's wrong here
VLANs segment Layer 2, but do not provide independent firewall contexts.
