- A
VDOM configuration, including interfaces and policies, is synchronized between cluster members.
All configuration, including VDOM-specific settings, is synchronized in an HA cluster.
- B
In active-passive HA, traffic for each VDOM can be distributed across cluster members.
Why wrong: In active-passive, only one unit is active for all VDOMs; traffic distribution is not supported.
- C
Each VDOM can have its own HA mode (active-passive or active-active) independent of the global HA mode.
Why wrong: HA mode is global for the entire FortiGate; VDOMs cannot have independent HA modes.
- D
The HA virtual MAC address feature can be enabled per VDOM to handle ARP issues during failover.
Virtual MAC can be configured per VDOM to ensure seamless failover.
- E
If one VDOM fails, the entire HA cluster fails over to the standby unit.
Why wrong: VDOM failure does not trigger HA failover; HA monitors the entire FortiGate health.
Quick Answer
The correct answer is that the HA virtual MAC address feature can be enabled per VDOM to handle ARP issues during failover. This is correct because in a FortiGate active-passive HA cluster, VDOM synchronization ensures that all configuration elements—including interfaces, policies, and routing—are fully replicated from the active unit to the passive unit, so both members share an identical configuration for each VDOM. On the Fortinet NSE 7 Advanced Security NSE7 exam, this concept tests your understanding of how granular synchronization works across VDOMs, and a common trap is assuming that only global settings are synced or that per-VDOM virtual MACs are optional only for transparent mode. Remember that without per-VDOM virtual MACs, ARP tables on upstream switches can become stale during failover, causing traffic blackholing. A helpful memory tip: “VDOM sync is full, but ARP needs a virtual MAC to stay stable.”
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.
A FortiGate HA cluster is configured with VDOMs. Each VDOM is assigned to different physical interfaces. The cluster is in active-passive mode. Which TWO statements about VDOM synchronization in HA are correct?
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
VDOM configuration, including interfaces and policies, is synchronized between cluster members.
Option A is correct because in a FortiGate HA cluster, VDOM configuration—including interfaces, policies, and other settings—is fully synchronized between cluster members. This ensures that both the active and passive units have identical VDOM configurations, enabling seamless failover without manual reconfiguration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse VDOM-level failover behavior with global HA failover, mistakenly thinking a single VDOM failure triggers a full cluster failover, when in reality FortiGate HA only fails over on unit-level failures.
Detailed technical explanation
How to think about this question
VDOM synchronization in HA relies on the FortiGate's configuration synchronization mechanism, which uses the HA heartbeat link to replicate all VDOM-specific settings, including interface assignments, firewall policies, and routing tables. The virtual MAC address feature (Option D) is critical in active-passive HA to prevent ARP table flapping during failover; it assigns a unique virtual MAC per VDOM interface, ensuring that the standby unit can seamlessly take over traffic without requiring ARP updates from connected switches.
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.
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 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.
