If the Services field is configured in a Virtual IP (VIP), which statement is true when central NAT is used?
Correct Answer:
C
FortiGate is operating in NAT mode and is configured with two virtual LAN (VLAN) subinterfaces added to the same physical interface.
In this scenario, what are two requirements for the VLAN ID? (Choose two.)

https://community.fortinet.com/t5/FortiGate/Technical-Note-How-to-use-emac-vlan-to-share-the-same-VLAN/t 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.
A network administrator wants to set up redundant IPsec VPN tunnels on FortiGate by using two IPsec VPN tunnels and static routes.
* All traffic must be routed through the primary tunnel when both tunnels are up
* The secondary tunnel must be used only if the primary tunnel goes down
* In addition, FortiGate should be able to detect a dead tunnel to speed up tunnel failover
Which two key configuration changes are needed on FortiGate to meet the design requirements? (Choose two,)

Study Guide – IPsec VPN – IPsec configuration – Phase 1 Network.
When Dead Peer Detection (DPD) is enabled, DPD probes are sent to detect a failed tunnel and bring it down before its IPsec SAs expire. This failure detection mechanism is very useful when you have redundant paths to the same destination, and you want to failover to a backup connection when the primary connection fails to keep the connectivity between the sites up.
There are three DPD modes. On demand is the default mode. Study Guide – IPsec VPN – Redundant VPNs.
Add one phase 1 configuration for each tunnel. DPD should be enabled on both ends. Add at least one phase 2 definition for each phase 1.
Add one static route for each path. Use distance or priority to select primary routes over backup routes (routes for the primary VPN must have a lower distance or lower priority than the backup). Alternatively, use dynamic routing.
Configure FW policies for each IPsec interface.
An organization requires remote users to send external application data running on their PCs and access FTP resources through an SSL/TLS connection.
Which FortiGate configuration can achieve this goal?
Correct Answer:
B
FortiGate Infrastructure 7.2 Study Guide (p.198): "Tunnel mode requires FortiClient to connect to FortiGate. FortiClient adds a virtual network adapter identified as fortissl to the user’s PC. This virtual adapter dynamically receives an IP address from FortiGate each time FortiGate establishes a new VPN connection. Inside the tunnel, all traffic is SSL/TLS encapsulated. The main advantage of tunnel mode over web mode is that after the VPN is established, any IP network application running on the client can send traffic through the tunnel."
An SSL VPN tunnel allows remote users to establish a secure and encrypted Virtual Private Network (VPN) connection to the private network using the SSL/TLS protocol1. An SSL VPN tunnel can provide access to network resources such as FTP servers, as well as external applications running on the user’s PC1.
An SSL VPN bookmark is a web link that provides access to network resources through the SSL VPN web portal1. It does not support external applications running on the user’s PC.
Zero trust network access (ZTNA) is a security model that provides role-based application access to remote users without exposing the private network to the internet2. It does not use SSL/TLS protocol, but rather a proprietary ZTNA protocol.
SSL VPN quick connection is a feature that allows users to connect to an SSL VPN tunnel without installing FortiClient or any other software on their PC3. It requires a web browser that supports Java or ActiveX. It does not support external applications running on the user’s PC.
Which two settings can be separately configured per VDOM on a FortiGate device? (Choose two.)
Correct Answer:
CD
C: "Operating mode is per-VDOM setting. You can combine transparent mode VDOM's with NAT mode VDOMs on the same physical Fortigate.
D: "Inspection-mode selection has moved from VDOM to firewall policy, and the default inspection-mode is flow, so NGFW Mode can be changed from Profile-base (Default) to Policy-base directly in System > Settings from the VDOM" Page 125 of FortiGate_Infrastructure_6.4_Study_Guide
