In the context of SD-WAN, the terms underlay and overlay are commonly used to categorize links.
Which two statements about underlay and overlay links are correct? (Choose two.)

• A. Only wired connections can be used as underlay links.
• B. FortiLink interface is considered a underlay link.
• C. A VLAN is a type of overlay link.
• D. Wireless connections can be used to build overlay links.
• E. Overlay links provide routing flexibility.

An administrator is attempting to create two static routes: one for the SD-WAN zone wan-link and one pointing to a specific SD-WAN member interface that currently belongs to the wan-link zone.
Which configuration is required to make this scenario valid? (Choose one answer.)

• A. The destination subnet configured on the SD-WAN zone cannot be a default route.
• B. The destination subnets of the two static routes must be different.
• C. SD-WAN member must be an IPsec interface.
• D. Both routes must have the same administrative distance to allow equal-cost multipath (ECMP).

When you deploy SD-WAN, you can choose from several common designs. Each design best applies to specific contexts. Which two statements correctly associate a common SD-WAN design with its main indication or constraint? Choose two answers.

• A. Use a standalone design for sites with only one WAN link to the cloud.
• B. Use remote breakout to centralize traffic inspection and limit local management requirements.
• C. Use a direct internet access (DIA) design to increase the traffic security and allow local devices with limited capabilities.
• D. Use a cloud on-ramp topology to improve the performance of cloud applications.

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?

Exhibit 1

• A. Enable the applications as destinations of the SD-WAN rule feature visibility.
• B. In the Internet service field, select Facebook and LinkedIn.
• C. Install a license to allow applications as destinations of SD-WAN rules.
• D. You cannot configure applications as destinations of an SD-WAN rule on a standalone FortiGate device.

Which statement describes FortiGate behavior when you reference a zone in a static route?

• A. FortiGate installs a static route for each member in the zone.
• B. FoftiGate installs ECMP static routes for the first two members of the zone.
• C. FortiGate routes the traffic through the best performing member of the zone.
• D. FortiGate ignores the static routes defined through members referenced in the zone.
