NSE7 Enterprise Firewall and VDOMs Practice Question
Exhibit
config system interface edit "port1" set vdom "root" set ip 10.0.1.1 255.255.255.0 set allowaccess ping https ssh snmp set type physical set role wan next end config system admin edit "admin" set trusthost1 192.168.1.0 255.255.255.0 next end
Refer to the exhibit. A FortiGate is configured with the above settings. The FortiManager at 192.168.1.100 cannot establish a management connection to the FortiGate. What is the most likely cause?
⚠ Common exam trap
The trap here is that candidates may focus on the HTTPS access or trusthost settings, but the exhibit clearly shows the subnet mismatch between the FortiGate's port1 IP (10.0.1.1) and the FortiManager's IP (192.168.1.100), which is the fundamental Layer 3 connectivity issue that prevents the management session from being established.
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
✓
The FortiGate's port1 IP is not in the same subnet as the FortiManager
The FortiGate's port1 IP (10.0.1.1/24) is on a different subnet (10.0.1.0/24) than the FortiManager's IP (192.168.1.100), which is on the 192.168.1.0/24 subnet. For a management connection to be established, the FortiGate and FortiManager must be able to route to each other, typically requiring them to be on the same subnet unless a gateway or static route is configured. Since no routing is mentioned, the subnet mismatch is the most likely cause of the failure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
HTTPS access is not enabled on port1
Why it's wrong here
HTTPS is enabled in allowaccess.
- ✗
The admin user 'admin' is not configured correctly
Why it's wrong here
The admin user is present.
- ✓
The FortiGate's port1 IP is not in the same subnet as the FortiManager
Why this is correct
The management IP is 10.0.1.1, but FortiManager is on 192.168.1.0/24, so they are on different subnets.
- ✗
The trusthost configuration does not include the FortiManager IP
Why it's wrong here
The trusthost includes 192.168.1.0/24, which covers 192.168.1.100.
