Questions 1–5

   An SD-WAN rule uses the 'Lowest Cost (SLA)' strategy. The administrator notices that the rule is not using the cheapest link, even though the preferred (more expensive) link is meeting the SLA. The administrator checks the SLA target map and sees that the preferred link's latency is 50ms, which is below the threshold of 80ms defined in the target map. What is the most likely reason the cheaper link is not being used?

   • AThe cheaper link is also meeting the SLA, but the strategy is configured to always use the preferred link when both meet the SLA.
   • BThe preferred link is meeting the SLA, so the Lowest Cost (SLA) strategy continues to use it, even though it is more expensive.
   • CThe SLA target map is not applied to the SD-WAN rule, so the strategy is not using the SLA thresholds correctly.
   • DThe cheaper link has a higher cost metric, so the strategy is not considering it as a viable option.

   What is the primary goal of the 'load balancing' strategy in an SD-WAN rule?

   • ATo minimize the cost of the links used.
   • BTo distribute traffic across multiple WAN links to utilize bandwidth efficiently.
   • CTo ensure all traffic uses the primary link unless it is down.
   • DTo always use the link with the lowest latency.

   A FortiGate has a single SD-WAN rule that matches traffic to a specific application and uses the 'Load Balancing' strategy. All other traffic is handled by the implicit SD-WAN rule. The administrator wants to change the steering for the implicit rule to use the 'Best Quality' strategy. Where should this configuration be made?

   • AIn the SD-WAN settings, under the implicit rule, change the strategy to 'Best Quality'.
   • BChange the firewall policy that allows the traffic to use the 'Best Quality' strategy, overriding the SD-WAN rule.
   • CModify the existing SD-WAN rule to include all traffic by removing the application criteria, and set its strategy to 'Best Quality'.
   • DCreate a new user-defined SD-WAN rule with no criteria and set its strategy to 'Best Quality', placing it at the bottom of the rule list.

   In the FortiGate SD-WAN dashboard, what does the 'Status' column for an SD-WAN rule indicate?

   • AWhether the rule is currently enabled or disabled.
   • BThe number of packets that have matched the rule.
   • CThe performance metrics of the links selected by the rule.
   • DThe operational state of the rule, such as whether it is active and being used for steering.
