A. When all three members have the same packet loss
B. When HUB1-VPN1 has 4% packet loss
C. When HUB1-VPN1 has 12% packet loss
D. When HUB1-VPN3 has 4% packet loss

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.
