Question 590
An application control signature matches a cloud service but its SD-WAN steer rule directs it through a member without the needed source NAT configuration. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?
Explanation
Correct Answer
The intended applications traverse approved security policy and selected SD-WAN members with correct translation and bidirectional return traffic. This is the operational validation outcome rather than merely an enabled setting. Traffic must pass both policy and routing requirements; a correctly configured SD-WAN rule cannot override a denied firewall session or fix missing NAT. Scenario: An application control signature matches a cloud service but its SD-WAN steer rule directs it through a member without the needed source NAT configuration.
Incorrect Answers
Approved sessions recover over a permitted secondary member according to policy while unexpected fallback links remain excluded. This result would test SD-WAN implicit rules, failover decisions and session persistence but does not demonstrate the desired FortiGate outcome here. Verify instead: The intended applications traverse approved security policy and selected SD-WAN members with correct translation and bidirectional return traffic. Scenario: An application control signature matches a cloud service but its SD-WAN steer rule directs it through a member without the needed source NAT configuration.
Traffic uses the alternative route when the monitored upstream path fails, and the preferred path returns without oscillating under the configured hold-down policy. This result would test Link monitoring and static route failover triggers but does not demonstrate the desired FortiGate outcome here. Verify instead: The intended applications traverse approved security policy and selected SD-WAN members with correct translation and bidirectional return traffic. Scenario: An application control signature matches a cloud service but its SD-WAN steer rule directs it through a member without the needed source NAT configuration.
Traffic exits the intended interface through a reachable next hop and return connectivity works without a broader unapproved default route. This result would test FortiGate static default routes and interface reachability but does not demonstrate the desired FortiGate outcome here. Verify instead: The intended applications traverse approved security policy and selected SD-WAN members with correct translation and bidirectional return traffic. Scenario: An application control signature matches a cloud service but its SD-WAN steer rule directs it through a member without the needed source NAT configuration.
