The exhibit shows that the traffic's source IP (10.0.1.130) falls within the 10.0.1.128/255.255.255.128 subnet, and the destination IP (128.66.0.125) falls within the 128.66.0.0/255.255.255.0 subnet. This means the traffic explicitly matches the standard router policy configured under edit 1. The action for this policy route is set to deny. In FortiOS architecture, configuring a policy route with a deny action does not drop the traffic. Instead, it instructs the routing engine to halt policy route evaluation—effectively bypassing all subsequent policy routes and SD-WAN rules—and forces the FortiGate to route the traffic using standard static or dynamic routes found in the active routing table, which is the Forwarding Information Base (FIB).

A. FortiGate drops the traffic flow. Setting a deny action in a policy route stops policy-based routing evaluation; it does not drop the packet. Packet dropping is exclusively handled by firewall policies.

C. FortiGate load balances the traffic flow through port7 and port8. Because the traffic matches the standard deny policy route, it bypasses SD-WAN rule evaluation entirely, preventing SD-WAN load balancing algorithms from processing the flow.

D. FortiGate steers the traffic flow through port7. The deny action in the matched standard policy route preempts all SD-WAN rule processing. Therefore, traffic will not be steered by any configured SD-WAN service members or SLAs.
