Fortinet Fortinet NSE 4 - FortiOS 7.2 NSE4_FGT-7.2 Exam Dumps: Updated Questions & Answers (October 2025)

FortiGate Security 7.2 Study Guide (p.235): "If FortiGate receives a trusted SSL certificate, then it generates a temporary certificate signed by the built-in Fortinet_CA_SSL certificate and sends it to the browser. If the browser trusts the Fortinet_CA_SSL certificate, the browser completes the SSL handshake. Otherwise, the browser also presents a warning message informing the user that the site is untrusted. In other words, for this function to work as intended, you must import the Fortinet_CA_SSL certificate into the trusted root CA certificate store of your browser."

When FortiGate is operating in NAT mode, it means that it uses network address translation (NAT) to modify the source or destination IP addresses of the traffic passing through it1. NAT mode allows FortiGate to hide the IP addresses of the internal network from the external network, and to conserve IP addresses by using a single public IP address for multiple private IP addresses1.

A virtual LAN (VLAN) subinterface is a logical interface that allows traffic from different VLANs to enter and exit the FortiGate unit2. A VLAN subinterface is created by adding a VLAN ID to a physical interface or an aggregate interface2. A VLAN ID is a numerical identifier that distinguishes one VLAN from another2.

In this scenario, there are two requirements for the VLAN ID of the VLAN subinterfaces added to the same physical interface:

The two VLAN subinterfaces must have different VLAN IDs. This is because the VLAN ID is used to tag the traffic with the appropriate VLAN information, and to separate the traffic into different VLANs2. If the two VLAN subinterfaces have the same VLAN ID, they will not be able to distinguish the traffic from each other, and they will not be able to forward the traffic to the correct destination.

The two VLAN subinterfaces can have the same VLAN ID, only if they belong to different VDOMs. This is because VDOMs are virtual instances of FortiGate that can have their own interfaces, policies, and routing tables3. Each VDOM operates independently from other VDOMs, and can have its own VLAN subinterfaces with different or identical VLAN IDs3. However, this requires inter-VDOM links to allow traffic between different VDOMs3.

FortiGate Security 7.2 Study Guide (p.385): "The IPS engine is responsible for most of the features shown in this lesson: IPS and protocol decoders. It’s also responsible for application control, flow-based antivirus protection, web filtering, and email filtering."

When a packet arrives, how does FortiGate find a matching policy? Each policy has match criteria, which

you can define using the following objects:

• Incoming Interface

• Outgoing Interface

• Source: IP address, user, internet services

• Destination: IP address or internet services

• Service: IP protocol and port number

• Schedule: Applies during configured times
