NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator manages a FortiGate 500E with multiple VDOMs. The administrator needs to configure a new VDOM named 'Partner' and ensure that the Partner VDOM can use a dedicated physical interface for WAN connectivity. The FortiGate has an unused interface 'port5'. The administrator wants to assign port5 to the Partner VDOM and configure it with an IP address. Which sequence of steps is correct?
⚠ Common exam trap
The trap here is attempting to configure the interface IP address before moving it to the VDOM, or trying to create a new interface within the VDOM; physical interfaces must be moved from global first.
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
✓
In the global configuration, edit port5 and set its VDOM to 'Partner'. Then, within the Partner VDOM, configure the IP address on port5.
Physical interfaces are assigned to VDOMs from the global configuration by editing the interface and setting its VDOM attribute. Once the interface belongs to the Partner VDOM, you can enter that VDOM and configure the IP address and other settings. This is the correct and only method to dedicate a physical interface to a VDOM.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
In the global configuration, edit port5 and set its VDOM to 'Partner'. Then, within the Partner VDOM, configure the IP address on port5.
Why this is correct
To assign a physical interface to a VDOM, you must first move the interface to that VDOM in the global configuration. After the interface is in the Partner VDOM, you can then configure its IP address and other settings within that VDOM's context. This two-step process is required because interface ownership is defined at the global level.
- ✗
Enable 'vdom-link' on port5 and assign it to the Partner VDOM, then configure the IP address.
Why it's wrong here
A VDOM link is a virtual interface pair used for inter-VDOM routing, not a physical interface assignment. Enabling 'vdom-link' on port5 is not a valid configuration; VDOM links are created separately. This would not assign the physical interface to the Partner VDOM and would not provide WAN connectivity.
- ✗
In the global configuration, create a virtual interface and bind it to port5, then assign it to the Partner VDOM.
Why it's wrong here
Virtual interfaces (like VLANs) are created within a VDOM, not globally, and they are bound to a parent interface. However, the requirement is to use the physical interface port5 directly, not a virtual interface. Creating a virtual interface would add unnecessary complexity and not meet the goal.
- ✗
Within the Partner VDOM, create a new interface and map it to port5 using the 'set interface' command.
Why it's wrong here
There is no command to create a new interface and map it to a physical port within a VDOM. Physical interfaces are predefined and must be moved to a VDOM from the global configuration. The 'set interface' command is not used for this purpose, and attempting this would fail.
