- (Exam Topic 1) A network administrator wants to set up redundant IPsec VPN tunnels on FortiGate by using two IPsec VPN tunnels and static routes. * All traffic must be routed through the primary tunnel when both tunnels are up * The secondary tunnel must be used only if the primary tunnel goes down * In addition, FortiGate should be able to detect a dead tunnel to speed up tunnel failover Which two key configuration changes are needed on FortiGate to meet the design requirements? (Choose two,)
A. Configure a high distance on the static route for the primary tunnel, and a lower distance on the static route for the secondary tunnel
B. Enable Dead Peer Detection
C. Configure a lower distance on the static route for the primary tunnel, and a higher distance on the static route for the secondary tunnel
D. Enable Auto-negotiate and Autokey Keep Alive on the phase 2 configuration of both tunnels
