A company with a hub-and-spoke SD-WAN topology uses FortiGates at each site. The hub has two WAN links: MPLS (10 Mbps) and broadband (100 Mbps). The spokes connect only via MPLS. The company deploys a new real-time application that requires low latency and low jitter. The network administrator creates an SD-WAN rule for this application with 'best quality' strategy and both MPLS and broadband as members. The SLA for MPLS is configured with latency < 10 ms and jitter < 5 ms. The SLA for broadband is configured with latency < 50 ms and jitter < 20 ms.

A company has two internet connections: a primary fiber link (port1, 100 Mbps) and a backup DSL link (port2, 20 Mbps). They are using SD-WAN to load balance traffic based on volume, with a rule that sends 70% of traffic to port1 and 30% to port2. Recently, users report that video conferencing applications are experiencing high latency and jitter. The network team finds that the SD-WAN performance SLA for the fiber link shows 80% packet loss and high latency. The SD-WAN rule action is set to 'best quality' with a latency threshold of 150 ms. The current latency on port1 is 200 ms, and on port2 is 40 ms. What should the administrator do to ensure that video conferencing traffic uses the DSL link while the fiber link is degraded?
