NSE7-SSE-AR-26: Fortinet NSE 7 - FortiSASE 26 Architect

With passive measurement enabled and Facebook and YouTube specified in the SD-WAN rule, FortiGate separately collects SLA information for those applications and calculates the member SLA metrics from the relevant application data; where multiple applications are specified, the metric is their average. Passive WAN health measurement analyzes session information from TCP traffic allowed by the firewall policy. A passive health check uses live traffic rather than declaring a member dead merely because this application traffic is absent.
