In FortiOS SD-WAN, what is a virtual SD-WAN interface?

A loopback interface used for management traffic only.

A physical interface that is dedicated to SD-WAN traffic only.

A software-defined interface that requires a separate license for each member.

A logical interface that groups multiple physical WAN members for SD-WAN policy and routing.

Which scenario best describes the SD-WAN use case of WAN aggregation?

Using multiple WAN links together to increase total bandwidth for all traffic.

Replacing all physical links with a single virtual circuit.

Using a single high-cost MPLS link for all traffic to ensure reliability.

Keeping one link idle as a backup and only using it when the primary fails.

What does the 'quality status' of an SD-WAN link indicate?

The health of the link based on measured metrics like latency, jitter, and packet loss.

The cost of the link per megabyte.

The amount of bandwidth currently used on the link.

The physical condition of the cable connecting the router to the ISP.

In FortiOS SD-WAN, what is the primary function of an SD-WAN rule?

To configure the IP address of each physical WAN interface.

To enable or disable the SD-WAN feature globally.

To define which applications or destinations use which WAN members and how traffic is load-balanced.

To set the administrative distance for all routes.

In SD-WAN load balancing, what is the purpose of configuring a 'preferred member' in an SD-WAN rule?

To enable NAT on that interface.

To define the administrative distance for that link.

To specify which WAN link should be used first for the matched traffic, with others as backup.

To set the maximum bandwidth for that link.
