   An administrator is configuring an ICMP-based SLA probe on a FortiGate SD-WAN member. The probe target is a public server at 8.8.8.8. The administrator wants to ensure the probe is sent from the correct source interface so that the response returns via the same link. Which configuration is required?

   • ASet the destination port to 8.8.8.8.
   • BSet the source IP to the IP address of the SD-WAN member's interface.
   • CSet the probe interval to 1 second to ensure the source interface is used.
   • DSet the packet size to 64 bytes to match the default ICMP size.

   When configuring an SLA target on an SD-WAN interface in FortiGate, which elements must be specified?

   • AMonitoring protocol, probe interval, and threshold values for latency, jitter, and packet loss
   • BFirewall policy ID, source address, and destination address
   • CInterface IP address, subnet mask, and default gateway
   • DVPN tunnel name, encryption algorithm, and pre-shared key

   A company's SD-WAN link to a branch office is experiencing intermittent voice quality issues. The administrator suspects the ISP is prioritizing certain traffic, which might affect the real user experience. The current SLA uses ICMP probes to a public IP. The administrator wants to measure the link quality in a way that more closely reflects actual voice traffic. Which approach should be taken?

   • AConfigure a passive monitoring method that inspects actual voice traffic flowing through the FortiGate to measure latency, jitter, and loss.
   • BKeep ICMP probes but increase the probe packet size to 1400 bytes to better simulate voice payloads.
   • CUse a TCP-based probe to a well-known port (e.g., 443) on a public server to simulate a real session.
   • DChange the probe target to the ISP's gateway IP address to reduce the number of hops.

   In FortiGate SD-WAN, where do you configure the action to take when an SLA target fails?

   • AIn the firewall policy, by enabling 'sla-failover'
   • BIn the SD-WAN rule, by specifying the preferred members and the members to use when the preferred members fail SLA
   • CIn the SLA target configuration, by setting a 'failover-action' parameter
   • DIn the interface configuration, by setting 'sla-action'
