NSE7 Enterprise Firewall and VDOMs Practice Question
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?
⚠ Common exam trap
A common mix-up: candidates 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.
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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
VDOM configuration, including interfaces and policies, is synchronized between cluster members.
Why this is correct
All configuration, including VDOM-specific settings, is synchronized in an HA cluster.
- ✗
In active-passive HA, traffic for each VDOM can be distributed across cluster members.
Why it's wrong here
In active-passive, only one unit is active for all VDOMs; traffic distribution is not supported.
- ✗
Each VDOM can have its own HA mode (active-passive or active-active) independent of the global HA mode.
Why it's wrong here
HA mode is global for the entire FortiGate; VDOMs cannot have independent HA modes.
- ✓
The HA virtual MAC address feature can be enabled per VDOM to handle ARP issues during failover.
Why this is correct
Virtual MAC can be configured per VDOM to ensure seamless failover.
- ✗
If one VDOM fails, the entire HA cluster fails over to the standby unit.
Why it's wrong here
VDOM failure does not trigger HA failover; HA monitors the entire FortiGate health.
