A FortiGate is experiencing high CPU usage due to a large number of sessions. Which TWO actions can the admin take to mitigate the issue? (Choose two.)

An administrator is troubleshooting an SD-WAN scenario where traffic from a branch office to a critical SaaS application is experiencing high latency. The SD-WAN rule uses the best quality SLA strategy. The administrator runs 'diagnose sys sdwan neighbor' and sees that both WAN links have SLA compliance above 90%. However, traffic still uses the slower link. The administrator then runs 'diagnose sys sdwan health-check list' and notices that the health-check server IP is different from the SaaS application's server IP. What is the MOST likely reason the traffic is not using the best-performing link?

An administrator is testing failover in an HA cluster. They unplug the primary FortiGate's port1 (the heartbeat interface) but the secondary does not take over. The heartbeat is configured on port1. What is the MOST likely cause?

A FortiGate is deployed as the edge firewall for a medium-sized enterprise. The network has three internal zones: Trust (10.10.0.0/16), DMZ (172.16.0.0/24), and Guest (192.168.0.0/24). The FortiGate has an IPSec VPN to a branch office (10.20.0.0/16). Users in the Trust zone report intermittent connectivity to a web server in the DMZ (172.16.0.10, TCP port 443). The FortiGate logs show occasional 'session denied' messages for traffic from Trust to DMZ with reason 'denied by forward policy check'. The security policy has an explicit allow rule for Trust to DMZ HTTPS. The administrator has verified routing is correct and there are no address overlaps. When the issue occurs, the administrator runs 'diag debug flow' and sees that the packet matches the correct policy but still gets denied. The debug output also shows 'forward policy check: denied'. What is the most likely cause and recommended action?
