NEW QUESTION # 19
Refer to the exhibit. The administrator analyzed the traffic between a branch FortiGate and the server located in the data center, and noticed the behavior shown in the diagram. When the LAN clients located behind FGT1 establish a session to a server behind DC-1, the administrator observes that, on DC-1, the reply traffic is routed over T2. even though T1 is the preferred member in the matching SD-WAN rule.
What can the administrator do to instruct DC-1 to route the reply traffic through the member with the best performance?
- A. Enable auxiliary-session under config system settings.
- B. FortiGate route lookup for reply traffic only considers routes over the original ingress interface.
- C. Enable snat-route-change under config system global.
- D. Enable reply-session under config system sdwan.
Answer: A
NEW QUESTION # 20
Refer to the exhibits. The interface details, static route configuration, and firewall policies on the managed FortiGate device are shown.
You want to configure a new SD-WAN zone, named Underlay, that contains the interfaces port1 and port2.
What must be your first action?
- A. Delete the static routes.
- B. Define port1 as an SD-WAN member.
- C. Delete the SD-WAN Zone Test.
- D. Delete the firewall policies.
Answer: C
Explanation:
In the exhibits, port2 is already assigned to the SD-WAN zone named Test. An interface can only belong to a single SD-WAN zone, so before you can add both port1 and port2 into the new SD- WAN zone Underlay, you must first delete the SD-WAN Zone Test to free port2.
NEW QUESTION # 21
The FortiGate devices are managed by ForliManager, and are configured for direct internet access (DIA). You confirm that DIA is working as expected for each branch, and check the SD- WAN zone configuration and firewall policies shown in the exhibits.
Then, you use the SD-WAN overlay template to configure the IPsec overlay tunnels. You create the associated SD-WAN rules to connect existing branches to the company hub device and apply the changes on the branches.
After those changes, users complain that they lost internet access. DIA is no longer working.
Based on the exhibit, which statement best describes the possible root cause of this issue?
- A. The SD-WAN overlay template redefines the interface gateway addresses if they are defined with metadata variables.
- B. The SD-WAN overlay template defines a zone for each underlay interface and moves the interfaces into those zones.
- C. The SD-WAN overlay template didn't configure a firewall policy to allow traffic through the overlay.
- D. The SD-WAN overlay template updates the SD-WAN template and the rules.
Answer: B
Explanation:
The SD-WAN overlay template defines a zone for each underlay interface and moves the interfaces into those zones. This statement perfectly describes the likely sequence of events. The template, when applied, re-organizes the interfaces and zones, causing the existing firewall policy that relies on the old zone configuration to fail. This is the most plausible root cause.
NEW QUESTION # 22
You want FortiGate to use SD-WAN rules to steer local-out traffic.
Which two constraints should you consider? (Choose two.)
- A. By default, FortiGate uses SD-WAN rules only for local-out traffic that corresponds to ping and traceroute.
- B. You must configure each local-out feature individually to use SD-WAN.
- C. By default, local-out traffic does not use SD-WAN.
- D. You can steer local-out traffic only with SD-WAN rules that use the manual strategy.
Answer: B,C
Explanation:
By default, local-out traffic does not use SD-WAN # FortiGate normally sends local-out traffic (e.g., DNS, NTP, FortiGuard updates) directly through its interfaces without applying SD-WAN rules.
You must configure each local-out feature individually to use SD-WAN # To steer local-out traffic via SD- WAN, you must explicitly configure the desired local-out features (e.g., DNS, FortiGuard, CAPWAP) to use SD-WAN rules.
NEW QUESTION # 23
Refer to the exhibits. The exhibits show an SD-WAN event log, the member status, and the SD- WAN rule configuration.
Which two conclusions can you draw from the information shown? (Choose two.)
- A. The administrator configured the SD-WAN rule ID 1 with the default strategy mode.
- B. FortiGate updated the outgoing interface list on the rule so it prefers port2.
- C. Port2 has a lower latency than port1.
- D. The administrator configured the service ID 1 with the highest priority member for port2.
Answer: B,C
Explanation:
The SD-WAN rule (config service edit 1) is configured with set mode priority. This means the rule selects the best interface based on a defined performance metric, as opposed to a simple static priority or SLA. The event log (image_41cfb5.png) shows Metric latency and Message Service prioritized by performance metric will be redirected in sequence order. This indicates that the rule is using latency to determine the preferred member. Given that the log message is about a change, and the most logical reason for a change in a priority mode is that a different member is now the best performer, it implies that the latency on port2 has become lower than that on port1.
The log message Service prioritized by performance metric will be redirected in sequence order confirms that FortiGate is changing the member being used for this service. Because the mode is priority, FortiGate dynamically selects the member that currently meets the best performance criteria, which in this case is latency. The log implies a new member has been selected as the most optimal, and with the default configuration, the members are sorted based on their performance, so the outgoing interface list is effectively updated to prefer the new best- performing member (port2).
NEW QUESTION # 24
Refer to the exhibit.Two hub-and-spoke groups are connected through redundant site-to-site IPsec VPNs between Hub 1 and Hub 2.
Which two configuration settings are required for the spoke A1 to establish an ADVPN shortcut with the spoke B2? (Choose two.)
- A. On hubs, auto-discovery-forwarder must be enabled on the IPsec VPNs to hubs.
- B. On hubs, auto-discovery-forwarder must be enabled on the IPsec VPNs to spokes.
- C. On hubs, auto-discovery-receiver must be enabled on the IPsec VPNs to spokes.
- D. On hubs, auto-diacovery-sender must be enabled on the IPsec VPNs to spokes
Answer: A,D
NEW QUESTION # 25
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. You can delete the virtual-wan-link zones.
- B. The overlay-factories zone contains no member.
- C. You can move HUB1-VPN3 from the HUB1 zone to the overlay-shops zone.
- D. The underlay zone contains three members.
Answer: B
Explanation:
The overlay-factories zone is shown with a red icon, indicating that it has no members assigned to it, unlike the other zones which are expandable and show member interfaces.
NEW QUESTION # 26
Refer to the exhibit that shows an SD-WAN zone configuration on the FortiManager GUI.
Based on the exhibit, how will the FortiGate device behave after it receives this configuration?
- A. The configuration instructs FortiGate to choose an ADVPN shortcut based on SD-WAN information.
- B. The configuration instructs FortiGate to establish shortcuts only for overlay interfaces that meet the SLA target HUB1_HC.
- C. The configuration instructs FortiGate to establish shortcuts only when at least two members meet the SLA target.
- D. The configuration instructs FortiGate to allow ADVPN shortcuts for the tunnels of this SD-WAN zone.
Answer: C
Explanation:
This is because the setting minimum-sla-meet-members = 2 requires at least two SD-WAN zone members (in this case, HUB2-VPN1, HUB2-VPN2, and HUB2-VPN3) to pass the defined SLA health check (HUB1_HC) before the FortiGate will establish ADVPN shortcuts. If fewer than two members meet the SLA, shortcuts will not be created.
NEW QUESTION # 27 
Refer to the exhibit that shows event logs on FortiGate.
Based on the output shown in the exhibit, what can you say about the tunnels on this device?
- A. The master tunnel HU82-VPN3 cannot accept ADVPN shortcuts.
- B. The VPN tunnel HUB1-VPN1_0 is a shortcut tunnel.
- C. There is one shortcut tunnel built from master tunnel VPN4.
- D. The device steers voice traffic through the VPN tunnel HUB1-VPN3.
Answer: B
Explanation:
Event logs (from the exhibit) show how traffic is matched to SD-WAN rules and routed. The log output indicates that voice traffic is being routed through the HUB1-VPN3 tunnel. This matches SD-WAN's application-aware steering, which uses dynamic performance metrics to select the optimal path.

NEW QUESTION # 28
You have configured the performance SLA with the probe mode as Prefer Passive.
What are two observable impacts of this configuration? (Choose two.)
- A. FortiGate can offload the traffic that is subject to passive monitoring to hardware.
- B. After FortiGate switches to active mode, the SLA performance rule falls back to passive monitoring after 3 minutes.
- C. FortiGate passively monitors the member if ICMP traffic is passing through the member.
- D. FortiGate passively monitors the member if TCP traffic is passing through the member.
- E. During passive monitoring, the SLA performance rule cannot detect dead members.
Answer: C,D
Explanation:
FortiGate passively monitors the member if TCP traffic is passing through the member → With Prefer Passive mode, FortiGate inspects existing traffic (like TCP flows) to measure performance metrics without generating its own probes.
FortiGate passively monitors the member if ICMP traffic is passing through the member → Similarly, when ICMP flows exist, FortiGate uses them for SLA checks.
NEW QUESTION # 29 
Refer to the exhibit.
You want to configure SD-WAN on a network as shown in the exhibit.
The network contains many FortiGate devices. Some are used as NGFW, and some are installed with extensions such as FortiSwitch. FortiAP. or Forti Ex tender.
What should you consider when planning your deployment?
- A. You can build an SD-WAN topology that includes all devices. The hubs can be FortiGate devices with Forti Extender.
- B. You must build multiple SD-WAN topologies. Each topology must contain only one type of extension.
- C. You must use FortiManager to manage your SD-WAN topology.
- D. You can build an SD-WAN topology that includes all devices. The hubs must be devices without extensions.
Answer: D
Explanation:
In Fortinet SD-WAN, hubs should not have extensions like FortiSwitch, FortiAP, or FortiExtender installed, as these can affect hub functionality and scalability. While all device types can be included in the topology, the hubs must be "clean" FortiGate devices without such extensions to ensure proper ADVPN and overlay management.

NEW QUESTION # 30
Refer to the exhibit. An administrator is troubleshooting SD-WAN on FortiGate. A device behind branch1_fgt generates traffic to the 10.0.0.0/8 network.
The administrator expects the traffic to match SD-WAN rule ID 1 and be routed over HUB1- VPN1.
However, the traffic is routed over HUB1-VPN3.
Based on the output shown in the exhibit, which two reasons, individually or together, could explain the observed behavior? (Choose two.)
- A. HUB1-VPN3 has a lower route priority value (higher priority) than HUB1-VPN1.
- B. HUB1-VPN1 does not have a valid route to the destination
- C. HUB1-VPN3 has a higher member configuration priority than HUB1-VPN1
- D. The traffic matches a regular policy route configured with HUB1-VPN3 as the outgoing device
Answer: B,D
Explanation:
NEW QUESTION # 31
Refer to the exhibits.
Exhibit A
Exhibit B
Exhibit A shows a policy package definition. Exhibit B shows the install log that the administrator received when he tried to install the policy package on FortiGate devices.
Based on the output shown in the exhibits, what can the administrator do to solve the issue?
- A. Create dynamic mapping for the LAN interface for all devices in the installation target list.
- B. Policies can refer to only one LAN source interface. Keep only the D-LAN, which is the dynamic LAN interface.
- C. Use a metadata variable instead of a dynamic interface to define the firewall policy.
- D. Dynamic mapping should be done automatically. Review the LAN interface configuration for branch2_fgt.
Answer: A
NEW QUESTION # 32
Within the context of SD-WAN, what does SIA correspond to?
- A. Local Breakout
- B. Remote Breakout
- C. Secure Internet Authorization
- D. Software Internet Access
Answer: B
NEW QUESTION # 33
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 removes the layer 3 settings for interfaces that are removed from the SD-WAN configuration.
- B. FortiGate can remove some static routes associated with an interface when the member is removed from SD-WAN.
- C. FortiGate, with SD-WAN enabled, cannot route traffic through interfaces that are not SD-WAN members.
- D. FortiGate administratively brings down interfaces when they are removed from the SD-WAN configuration.
Answer: B
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 # 34
Which two statements correctly describe what happens when traffic matches the implicit SD-WAN rule? (Choose two.)
- A. The session information output displays no SD-WAN service id.
- B. Traffic does not match any of the entries in the policy route table.
- C. FortiGate flags the session with may_dirty and vwl_def ault.
- D. The traffic is distributed, regardless of weight, through all available static routes.
- E. Traffic is load balanced using the algorithm set for the v4-ecmp-mode setting.
Answer: A,B
NEW QUESTION # 35
When you use the command diagnose sys session list, how do you identify the sessions that correspond to traffic steered according to SD-WAN rules?
- A. You identify sessions steered according to SD-WAN rules with the data vwl_mbr_seq.
- B. You identify sessions steered according to SD-WAN rules with the data 3dwan_service_id.
- C. You cannot identify SD-WAN sessions. You must use the sdwar. session filter.
- D. You identify sessions steered according to SD-WAN rules with the flag vwl.
Answer: B
Explanation:
When using the diagnose sys session list command, SD-WAN-specific session steering is indicated by the presence of the sdwan_service_id field in the session data. This identifier ties the session directly to a specific SD-WAN rule or service. As noted in the Fortinet documentation: "Sessions that are handled according to SD- WAN rules will include a service ID tag (sdwan_service_id) in their session listing. This allows administrators to correlate live sessions with SD-WAN policy matches for troubleshooting and visibility." This is a crucial diagnostic tool, as it distinguishes between traffic managed by traditional routing and that explicitly controlled by SD-WAN steering logic, aiding in operational insight and troubleshooting.

NEW QUESTION # 36
Refer to the exhibit. You configure SD-WAN on a standalone FortiGate device. You want to create an SD-WAN rule that steers Facebook and Linkedin traffic through the less costly internet link. The FortiGate GUI page appears as shown in the exhibit.
What should you do to set Facebook and LinkedIn as destinations?
- A. In the Internet service field, select Facebook and LinkedIn.
- B. You cannot configure applications as destinations of an SD-WAN rule on a standalone FortiGate device.
- C. Enable the applications as destinations of the SD-WAN rule feature visibility.
- D. Install a license to allow applications as destinations of SD-WAN rules.
Answer: A
Explanation:
In an SD-WAN rule, you can steer application traffic by using Internet Service Database (ISDB) entries. Facebook and LinkedIn are predefined ISDB objects in FortiGate, so the correct way is to select them in the Internet service field under Destination. This ensures that all traffic to these applications is matched and routed through the chosen (less costly) link.
NEW QUESTION # 37
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. The administrator must manually assign the tunnel interface IP address on the hub side
- C. The remote end must support IKEv2.
- D. The tunnel interface IP address on the spoke side is provided by the hub.
- E. This configuration allows user-defined overlay IP addresses.
Answer: A,B,C
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.
