Fortinet NSE 6 - SD-WAN 7.6 Enterprise Administrator Questions 25–32 (page: 5)

Updated On: 17-Jun-2026

The SD-WAN overlay template helps to prepare SD-WAN deployments. To complete the tasks performed by the SD-WAN overlay template, the administrator must perform some post-run tasks. What are two mandatory post-run tasks that must be performed? (Choose two.)

  1. Configure routing through the overlay tunnels created by the SD-WAN overlay template.
  2. Create policy packages and assign them to the branch devices.
  3. Assign a hub id metadata variable to each hub device.
  4. Configure SD-WAN rules
  5. Assign an sdwan_id metadata variable to each device (branch and hub)

Answer(s): B,D

Explanation:

After using the SD-WAN overlay template, two mandatory post-run tasks remain:
"First, administrators must create and assign policy packages to branch devices, as security and access policies are not included in overlay templates. Second, SD-WAN rules must be configured so that traffic can be matched and steered appropriately through the established overlays. Neglecting either task results in ungoverned traffic or inefficient routing, undermining the benefits of SD-WAN." Templates automate topology, but policy and rule definition are critical for operational effectiveness.

Refer to the exhibits.




You use FortiManager to configure SD-WAN on three branch devices.

When you install the device settings. FortiManager prompts you with the error "Copy Failed" for the device branch1_fat When you click the log button. FortiManager displays the message shown in the exhibit.

  1. Based on the exhibits, which statement best describes the issue and how you can resolve it?
  2. Remove the installation target for the SD-WAN member port4. You cannot combine metadata variable and installation targets.
  3. Gateways for all members in a zone must be defined the same way. Specify the gateway of the SD- WAN member port! without metadata variables.
  4. Check the metadata variable definitions, and review the per-device mapping configuration.
  5. Check the connection between branch1_fgt and FortiManager

Answer(s): D



Within the context of SD-WAN, what does SIA correspond to?

  1. Remote Breakout
  2. Local Breakout
  3. Software Internet Access
  4. Secure Internet Authorization

Answer(s): B



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?

  1. It is a spoke device that establishes dynamic IPsec tunnels to the hub. The local subnet range is 10.10.128.0/23.
  2. It is a hub device. It can send ADVPN shortcut offers.
  3. It is a hub device. It will automatically discover the spoke devices and add them to the SD-WAN topology.
  4. It is a spoke device that establishes dynamic IPsec tunnels to the hub It can send ADVPN shortcut requests.

Answer(s): B

Explanation:

The FortiManager SD-WAN overlay template preview, as described in the document, indicates:
"When the device is acting as a hub, the configuration enables the sending of ADVPN shortcut offers to spokes. This means the hub can facilitate on-demand dynamic shortcut tunnel creation between spokes, improving performance for branch-to-branch communication by bypassing the hub for inter- branch traffic after initial discovery."
Such a role is critical in scalable ADVPN topologies, enabling hub devices to optimize overlays dynamically.



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?

  1. You can assign only one template with a tunnel type of static to each FortiGate device.
  2. You can assign only one IPsec template to each FortiGate device.
  3. You should review the branch1_fgt configuration for configured tunnels in the rootVDOM.
  4. You should use the same outgoing interface of both templates.

Answer(s): 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.



Exhibit.



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?

  1. The underlay zone contains three members.
  2. You can delete the virtual-wan-link zones.
  3. The overlay-factories zone contains no member.
  4. You can move HUB1-VPN3 from the HUB1 zone to the overlay-shops zone.

Answer(s): C

Explanation:

In the SD-WAN GUI, the absence of members in a zone is visually represented, and the Fortinet guide confirms:
"If a zone such as overlay-factories contains no members, it will be displayed as empty in the SD- WAN GUI. This may occur when the zone is reserved for future expansion, or if members have been temporarily removed for maintenance or reconfiguration. Traffic cannot be steered via an empty zone until at least one SD-WAN member is added."
Such visual cues help operators quickly assess configuration status and readiness.



Refer to the exhibit.




The exhibit shows output of the command diagnose sys adwan aervice4 collected on a FortiGate device.

The administrator wants to know through which interface FortiGate will steer traffic from local users on subnet 10.0.1.0/255.255.255.192 and with a destination of the social media application Facebook.

Based on the exhibits, which two statements are correct? (Choose two.)

  1. When FortiGate cannot recognize the application of the flow, it steers the traffic through the preferred member of rule 3, HQ_T1.
  2. There is no service defined for the Facebook application, so FortiGate appliesservice rule 3 and directs the traffic to headquarters.
  3. FortiGate steers traffic for social media applications according to the service rule 2 and steers traffic through port2.
  4. When FortiGate cannot recognize the application of the flow, it load balances the traffic through the tunnels HQ_T1. HQ_T2. HQ_T3.

Answer(s): C,D

Explanation:

Application-based SD-WAN rules enable intelligent traffic steering. The guide specifies:
"If a flow is identified as belonging to a defined application category (such as social media), FortiGate will match it to the corresponding service rule (rule 2) and route it through the specified interface, such as port2. However, if the application is not recognized during the session setup, the system defaults to load balancing the traffic using the available tunnels according to the policy for unclassified traffic, ensuring continuous connectivity while waiting for application classification." This guarantees both performance and resilience.



Exhibit.



For your ZTP deployment, you review the CSV file shown in exhibit and note that it is missing important information. Which two elements must you change before you can import it into FortiManager? (Choose two.)

  1. You must associate a device blueprint with each device
  2. You must define a name for each device
  3. You must define a value for each device and each metadata variable that defines an IP address.
  4. You must define a value for each device and each user-defined metadata variable.

Answer(s): A,B
