(Refer to the exhibits.

From the SD-WAN rule configuration (service ID 3 , name " Corp " ), the rule is configured as:

set mode sla

set load-balance enable

set hash-mode source-ip-based

set priority-members 3 4 5

Two SLAs are referenced under config sla

In the diagnose firewall proute list output for service=3 (Corp) , FortiGate shows the actual members considered for this rule and their SLA pass status:

oif=19 (HUB1-VPN1) num_pass=2

oif=20 (HUB1-VPN2) num_pass=2

oif=21 (HUB1-VPN3) num_pass=1

Because the rule is SLA-based , FortiGate selects only members that meet the SLA requirements for the rule. The output indicates that HUB1-VPN1 and HUB1-VPN2 pass both SLA checks (num_pass=2) , while HUB1-VPN3 passes only one (num_pass=1) and therefore is not selected as an eligible forwarding interface for this rule.

Since load-balance is enabled and the rule uses hash-mode source-ip-based, FortiGate will consistently choose an eligible member based on the source IP hash. For traffic sourced from 10.0.1.101 , the session can be steered through either HUB1-VPN1 or HUB1-VPN2 (whichever the hash selects), but not HUB1-VPN3.

Therefore, the correct answer is B .
