Which two statements about the Hub Selection Method in FortiSASE Secure Private Access (SPA) are...

According to the NSE7 SASE Enterprise Guide (Pages 64 & 153), FortiSASE utilizes an intelligent engine to manage connectivity to private resources through various selection methods:

Hub Health and Priority: FortiSASE incorporates a built-in SD-WAN engine for intelligent routing selection among established IPsec links. The health check IP address periodically receives performance metrics, including jitter, latency, and packet loss, for each service connection. In this mode, FortiSASE evaluates the available hubs and selects the one with the highest priority (the most preferred value) within each POP, provided that the hub meets the defined service-level agreement (SLA) requirements. For this configuration to function correctly, both FortiSASE and the SPA hub must use the same Autonomous System Number (ASN).

BGP Multiple Exit Discriminator (MED): This method leverages the standard BGP MED attribute, which allows an autonomous system to signal its preferred entry point to a peer. FortiSASE learns the MED values advertised by the configured hubs. The architecture is designed so that the lower the MED value, the more preferred the path is to the receiving router. Consistent with the "Zero Trust" and "Secure Access" principles, even when using BGP MED, the selection is gated by the health engine; therefore, the hub is only selected if it also satisfies the configured SLA thresholds.

While SLA thresholds can be configured, the primary logic for hub selection focuses on how priority and dynamic routing attributes (like MED) interact with the real-time health of the tunnel.
