Fortinet FCSS_SDW_AR-7.4 Dumps Questions Answers

Based on the provided scenario, when initiating a ping test to a device (10.0.1.101) behind the branch FortiGate, the test traffic is steered through port1. This is determined by analyzing the SD-WAN rules, interface priorities, and routing table on the branch device. In typical Fortinet SD-WAN configurations, the port used for steering is determined by a combination of static routes, SD-WAN rules, and interface health checks. If port1 is the preferred member for that traffic—due to route metrics, health check status, or explicit SD-WAN rule configuration—then all eligible traffic from the LAN to the destination will be forwarded through port1. This not only ensures optimal traffic flow but also leverages SD-WAN’s dynamic path selection features to provide resilience and application steering.

When referencing a zone in a static route, FortiGate’s behavior is described as:

"Referencing a zone in a static route causes FortiGate to install a static route for each member interface of the zone. This enables ECMP (Equal-Cost Multi-Path) and load balancing where supported and ensures that traffic can be steered over any valid zone member according to SD-WAN rules or standard routing."

This mechanism is fundamental to Fortinet’s implementation of SD-WAN and simplifies large, multi-interface deployments.

In FortiOS SD-WAN configurations, when setting up Direct Internet Access (DIA) using the GUI, you cannot select applications as thedestinationin SD-WAN rules. The destination field in these rules is designed for IP subnets or address objects only, due to how DIA policies are structured within FortiOS. This is a platform limitation: while application steering is supported forsourceor for application-aware routing, the destination field in DIA scenarios does not accept applications. Therefore, the GUI does not present the option, and administrators must instead define DIA SD-WAN rules by specifying IP addresses or address objects for destinations. This restriction helps maintain rule clarity and performance efficiency in large deployments.
