Refer to the exhibits.
Exhibit A -
Exhibit B -
Exhibit A shows the source NAT (SNAT) global setting and exhibit B shows the routing table on FortiGate.
Based on the exhibits, which two actions does FortiGate perform on existing sessions established over port2, if the administrator increases the static route priority on port2 to 20? (Choose two.)
When the priority of the static route on port2 is increased, the route selection may change, which affects existing sessions that were originally routed through port2. If SNAT is enabled and the SNAT route change feature is configured, FortiGate will update the gateway information for sessions using SNAT to route them through the new path, which in this case is port1. Additionally, the existing sessions will be flagged as dirty, making the system aware that the routing information has changed and needs to be updated.
B & C is correct. This is details on page 156 in the SD-WAN 7.2 study guide.
