Question 1
AdvancedRules and Routing · Configure SD-WAN rules
A multinational retail corporation is deploying Fortinet Secure SD-WAN across 500 locations. Each location has two WAN links: a high-cost, low-latency MPLS link (Member A) and a low-cost, high-bandwidth Broadband link (Member B). The administrator creates an SD-WAN zone named 'Overlay' containing both members.
The requirement is to route VoIP traffic over the MPLS link unless its latency exceeds 50ms, in which case it should fail over to Broadband. For all other traffic, the Broadband link should be used unless it is down.
Which combination of SD-WAN Rule configurations fulfills this requirement?
Answer and explanation
Correct answer: C
The 'Lowest Cost (SLA)' strategy is ideal here. It respects the interface preference (MPLS) as long as the SLA (50ms latency) is met. If the SLA fails, it switches to the next available member (Broadband) if configured in the preference list or based on cost. For the remaining traffic, a Manual or implicit rule preferring Broadband satisfies the second requirement.
