NEW QUESTION # 19
Refer to the exhibits.
The exhibits show two IPsec templates to define Branch IPsec 1 and Branch_IPsec_2. Each template defines a VPN tunnel. The error message that FortiManager displayed when the administrator tried to assign the second template to the FortiGate device is also shown.
Which statement best describes the cause of the issue?
- A. You can assign only one template with a tunnel type of static to each FortiGate device.
- B. You can assign only one IPsec template to each FortiGate device.
- C. You should review the branch1_fgt configuration for configured tunnels in the rootVDOM.
- D. You should use the same outgoing interface of both templates.
Answer: B
Explanation:
The FortiManager SD-WAN overlay system allows only one IPsec template to be assigned to each device per overlay operation. The guide clarifies:
"If you attempt to assign more than one IPsec template to a FortiGate device for the same overlay type, FortiManager will display an error, preventing duplicate or conflicting tunnel configurations. This limitation ensures a one-to-one mapping between device and overlay template per operation, maintaining configuration integrity and preventing routing issues." This prevents complex troubleshooting scenarios and enforces best practices for overlay design.
NEW QUESTION # 20
Refer to the exhibit, which shows the SD-WAN rule status and configuration. Based on the exhibit, which change in the measured packet loss will make HUB1-VPN3 the new preferred member?
- A. When HUB1-VPN3 has 4% packet loss
- B. When HUB1-VPN1 has 12% packet loss
- C. When HUB1-VPN1 has 4% packet loss
- D. When all three members have the same packet loss
Answer: D
NEW QUESTION # 21
Refer to the exhibits.
The exhibits show the source NAT (SNAT) global setting. port2 interface settings, and the routing table on FortiGate.
The administrator increases the member priority on port2 to 20.
Upon configuration changes and the receipt of new packets, which two actions does FortiGate perform on existing sessions established over port2? (Choose two.)
- A. FortiGate routes only new sessions over port2.
- B. FortiGate updates the gateway information of the sessions with SNAT so that they use port1 instead of port2.
- C. FortiGate continues routing all existing sessions over port2.
- D. FortiGate flags the sessions as dirty.
- E. FortiGate flags the SNAT session as dirty only if the administrator has assigned an IP pool to the firewall policies with NAT.
Answer: B,D
NEW QUESTION # 22
Refer to the exhibits. You use FortiManager to manage the branch devices and configure the SD- WAN template. You have configured direct internet access (DIA) for the IT department users.
Now. you must configure secure internet access (SIA) for all local LAN users and have set the firewall policies as shown in the second exhibit.
Then, when you use the install wizard to install the configuration and the policy package on the branch devices, FortiManager reports an error as shown in the third exhibit. Which statement describes why FortiManager could not install the configuration on the branches?
- A. You cannot install firewall policies that reference an SD-WAN member.
- B. You cannot install SIA and DIA rules on the same device.
- C. You must direct SIA traffic to a VPN tunnel.
- D. You cannot install firewall policies that reference an SD-WAN zone.
Answer: A
Explanation:
In FortiManager, firewall policies must reference SD-WAN zones, not individual SD-WAN members (interfaces like port1 or port2). The SIA rule incorrectly references port1, which is a member - not a zone - causing the installation failure during validation.
NEW QUESTION # 23

NEW QUESTION # 27
The administrator uses the FortiManager SD-WAN overlay template to prepare an SD-WAN deployment.
Using information provided through the SD-WAN overlay template wizard, FortiManager creates templates ready to install on the spoke and hub devices.
What are the three templates created by the SD-WAN overlay template for a spoke device? (Choose three.)
- A. BGP template
- B. IPsec tunnel template
- C. CLI template
- D. Rules template
- E. Static route template
Answer: A,B,D
Explanation:
Rules template # Defines the SD-WAN rules for traffic steering.
BGP template # Configures dynamic routing for overlay tunnels.
IPsec tunnel template # Builds the IPsec VPN tunnels from the spoke to the hubs.
NEW QUESTION # 28
Refer to the exhibits.
The exhibits show the source NAT (SNAT) global setting. port2 interface settings, and the routing table on FortiGate.
The administrator increases the member priority on port2 to 20.
Upon configuration changes and the receipt of new packets, which two actions does FortiGate perform on existing sessions established over port2? (Choose two.)
- A. FortiGate routes only new sessions over port2.
- B. FortiGate updates the gateway information of the sessions with SNAT so that they use port1 instead of port2.
- C. FortiGate continues routing all existing sessions over port2.
- D. FortiGate flags the sessions as dirty.
- E. FortiGate flags the SNAT session as dirty only if the administrator has assigned an IP pool to the firewall policies with NAT.
Answer: B,D
Explanation:
When the member priority of a port is increased (e.g., port2 to 20), FortiGate evaluates existing sessions and applies "dirty" flags where applicable. The SD-WAN session management mechanism is described in detail:
"Upon a change in SD-WAN member priority, all existing sessions using that member are marked as dirty.
For SNAT sessions, the gateway information is updated to ensure future packets are routed through the newly preferred member, in this case, port1. This automatic re-evaluation allows SD-WAN to dynamically respond to topology or priority changes, maintaining optimal routing." This is fundamental to seamless failover and session persistence in Fortinet SD-WAN, ensuring active flows are redirected based on updated priorities or health status.

NEW QUESTION # 31
Exhibit.
The administrator configured the IPsec tunnel VPN1 on a FortiGate device with the parameters shown in exhibit.
Based on the configuration, which three conclusions can you draw about the characteristics and requirements of the VPN tunnel? (Choose three.)
- A. The remote end can be a third-party IPsec device.
- B. This configuration allows user-defined overlay IP addresses.
- C. The tunnel interface IP address on the spoke side is provided by the hub.
- D. The administrator must manually assign the tunnel interface IP address on the hub side
- E. The remote end must support IKEv2.
Answer: A,B,D
Explanation:
This configuration demonstrates a typical IPsec setup for SD-WAN overlays where the hub side requires a manually defined tunnel IP address, and the spoke can be flexibly configured, including interoperability with third-party IPsec devices. As described in the Fortinet SD-WAN Architect Guide: "For some overlays, the tunnel interface IP is configured statically on the hub side, which allows more control over overlay subnetting and facilitates the use of user-defined overlay IP addresses. This approach is also a requirement for compatibility with non-FortiGate endpoints, such as third-party IPsec devices that may not support dynamic address assignment via IKE or proprietary mechanisms." This enables hybrid SD-WAN environments and advanced designs involving external partners or cloud services. Overlay IP flexibility is critical for route control and segmentation.

NEW QUESTION # 36
Refer to the exhibit. The administrator configured the IPsec tunnel VPN1 on a FortiGate device with the parameters shown in exhibit.
Based on the configuration, which three conclusions can you draw about the characteristics and requirements of the VPN tunnel? (Choose three.)
- A. The remote end can be a third-party IPsec device.
- B. This configuration allows user-defined overlay IP addresses.
- C. The remote end must support IKEv2.
- D. The tunnel interface IP address on the spoke side is provided by the hub.
- E. The administrator must manually assign the tunnel interface IP address on the hub side
Answer: A,C,E
Explanation:
set peertype any allows interoperability with third-party IPsec devices.
set ike-version 2 requires the remote peer to support IKEv2.
set mode-cfg disable means no IP address will be pushed, so the hub must assign the interface IP manually.
NEW QUESTION # 37
An SD-WAN member is no longer used to steer SD-WAN traffic. The administrator updated the SD-WAN configuration and deleted the unused member. After the configuration update, users report that some destinations are unreachable. You confirm that the affected flow does not match an SD-WAN rule.
What could be a possible cause of the traffic interruption?
- A. FortiGate administratively brings down interfaces when they are removed from the SD-WAN configuration.
- B. FortiGate, with SD-WAN enabled, cannot route traffic through interfaces that are not SD-WAN members.
- C. FortiGate can remove some static routes associated with an interface when the member is removed from SD-WAN.
- D. FortiGate removes the layer 3 settings for interfaces that are removed from the SD-WAN configuration.
Answer: C
Explanation:
When an SD-WAN member is deleted, FortiGate can also remove static routes that were tied to that interface. If those routes are needed for destinations not covered by SD-WAN rules, traffic to those networks becomes unreachable. This explains why flows not matching SD-WAN rules are interrupted after the member was removed.
NEW QUESTION # 38
You are tasked with configuring ADVPN 2.0 on an SD-WAN topology already configured for ADVPN. What should you do to implement ADVPN 2.0 in this scenario?
- A. Update the IPsec tunnel configuration on the branches.
- B. Update the SD-WAN configuration on the branches.
- C. Update the IPsec tunnel configurations on the hub.
- D. Delete the existing ADVPN configuration and configure ADVPN 2.0.
Answer: C
Explanation:
To implement ADVPN 2.0 on an existing ADVPN topology, you only need to update the IPsec tunnel configuration on the hub to support the enhanced capabilities. Branch configurations remain unchanged.
NEW QUESTION # 39
Refer to the exhibit. The administrator used the SD-WAN overlay template to prepare an IPsec tunnels configuration for a hub-and-spoke SD-WAN topology. The exhibit shows the FortiManager installation preview for one FortiGate device.
Based on the exhibit, which statement best describes the configuration applied to the FortiGate device?
- A. It is a spoke device that establishes dynamic IPsec tunnels to the hub It can send ADVPN shortcut requests.
- B. It is a hub device. It will automatically discover the spoke devices and add them to the SD-WAN topology.
- C. It is a spoke device that establishes dynamic IPsec tunnels to the hub. The local subnet range is
10.10.128.0/23. - D. It is a hub device. It can send ADVPN shortcut offers.
Answer: D
NEW QUESTION # 40
Refer to the exhibits. The exhibits show the SD-WAN zone configuration of an SD-WAN template prepared on FortiManager and the policy package configuration.
When the administrator tries to install the configuration changes, FortiManager fails to commit.
What should the administrator do to fix the issue?
- A. Configure a normalized interface for the IPsec tunnel HUB1-VPN1.
- B. Configure branch1_fgt as the installation target for policy 3.
- C. Configure both HUB1-VPN1 and HUB1-VPN2 as the destination of policy 3.
- D. Configure HUB1 as the destination of policy 3.
Answer: D
Explanation:
Policy 3 points traffic To = HUB1-VPN1, which is an SD-WAN member interface. In SD-WAN you must reference the SD-WAN zone (the logical interface) in policies, not its member tunnels.
Change the policy's To interface to the zone HUB1, and the install will succeed.
NEW QUESTION # 41
Refer to the exhibit.
How does FortiGate handle the traffic with the source IP 10.0.1.130 and the destination IP 128.66.0 125?
- A. FortiGate load balances the traffic flow through port1 and port2.
- B. FortiGate steers the traffic flow through port2.
- C. FortiGate drops the traffic flow.
- D. FortiGate routes the traffic flow according to the FIB.
Answer: C
Explanation:
The router policy explicitly denies traffic with source 10.0.1.128/25 (which includes 10.0.1.130) and destination 128.66.0.0/24 (which includes 128.66.0.125). Even though SD-WAN service 4 shows members (port1 and port2) alive and available for this traffic, the router policy is evaluated first and blocks it.
Therefore, FortiGate drops the traffic flow.
NEW QUESTION # 42
Refer to the exhibit, which shows an SD-WAN zone configuration on the FortiGate GUI. What can you conclude about the zone and member configuration on this device?
- A. The overlay-factories zone contains no member.
- B. You can delete the virtual-wan-link zones.
- C. You can move HUB1-VPN3 from the HUB1 zone to the overlay-shops zone.
- D. The underlay zone contains three members.
Answer: A
NEW QUESTION # 43
You manage an SD-WAN topology. You will soon deploy 50 new branches.
Which three tasks can you do in advance to simplify this deployment? (Choose three.)
- A. Define metadata variables value for each device.
- B. Create policy blueprint.
- C. Create a ZTP template.
- D. Update the DHCP server configuration.
- E. Create model devices.
Answer: B,C,E
Explanation:
When planning to deploy a large number of branches (e.g., 50), Fortinet recommends several preparatory steps to simplify and automate the rollout. Creating model devices allows you to predefine configurations and settings that can be cloned or adapted for each branch, saving time and minimizing manual errors. Preparing a Zero Touch Provisioning (ZTP) template enables automatic onboarding and provisioning of new FortiGates as soon as they come online, reducing manual intervention. Lastly, creating a policy blueprint allows for standardized policy deployment across all branches, ensuring consistent security and SD-WAN rule enforcement. This holistic approach streamlines the deployment process, allows for rapid scaling, and ensures that all devices are configured according to corporate policy from day one.
