NSE7 Enterprise Firewall and VDOMs Practice Question
This NSE7 practice question tests your understanding of enterprise firewall and vdoms. 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.
Which TWO statements about VDOM limits on FortiGate are correct? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VDOM support requires a valid FortiGate license
Option C is correct because VDOM support on FortiGate is a licensed feature. Without a valid FortiGate license (e.g., an Advanced or Enterprise license bundle), the VDOM functionality is disabled, and the device operates in a single-VDOM (split-task) mode. This licensing requirement ensures that only authorized models and configurations can utilize VDOM isolation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
The maximum number of VDOMs is fixed per model and cannot be exceeded
Why this is correct
Each model has a hardware limit.

✗
VDOMs can be added without additional memory
Why it's wrong here
Each VDOM consumes memory.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume VDOMs are a free feature available on all models without licensing, or that VDOM count is unlimited, when in fact both a valid license and model-specific hard limits apply.
Detailed technical explanation
How to think about this question
Under the hood, each VDOM on FortiGate operates as an independent virtual firewall with its own routing table, firewall policies, and administrative domains. The maximum number of VDOMs is hard-coded per model (e.g., FortiGate 100F supports up to 10 VDOMs, while FortiGate 600F supports up to 500 VDOMs) and cannot be exceeded even with a license; the license only enables the feature. In real-world deployments, exceeding the VDOM limit without proper memory planning can cause performance degradation or crash the VDOM daemon (vdmd).

TExam Day Tips
→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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
