The correct answer is A. When all three members have the same packet loss.

In this rule, SD-WAN is using Best Quality with link-cost-factor packet-loss and link-cost-threshold 0.
That means FortiGate always selects the member with the lowest packet loss, and only if the packet loss is equal it uses the priority-members list (6 4 5) as a tiebreaker.
If all three members have the same loss, the highest-priority member (seq 6 = HUB1-VPN3) becomes the preferred one.

Option C is wrong because if HUB1-VPN1 has 12% loss, the losses are:

HUB1-VPN1: 12%

HUB1-VPN2: 4%

HUB1-VPN3: 12%

The lowest loss is 4%, so HUB1-VPN2 would be selected, not HUB1-VPN3.
I don´t understand why select C in the solution.

OH , the test mode said ""priority"", ""not"" ""Best quality"", in priority mode the correct is C Because the question assumes priority mode with tie-breaker: when HUB1-VPN1 reaches 12%, it is no longer the best, and the system may re-evaluate based on configured priorities (members 6 4 5). If HUB1-VPN1 becomes unhealthy or exceeds threshold, HUB1-VPN3 could be selected due to priority order.

Best answer is A , when all three have the same packet loss , it will select based on the configured priority

From the Fortinet Guide --> If you set link-cost-threshold to 0, then FortiGate performs a strict metric comparison. That is, there is no advantage, and the member with the best metric becomes preferred. If two or more members have the same metric, FortiGate uses the member priority (configuration order) as the tiebreaker.
