Question 310
An engineer changes a latency rule but the old long-lived sessions remain pinned to their previous SD-WAN member, confusing validation results. Which observable result BEST demonstrates that the intended FortiGate security or connectivity requirement is satisfied?
Explanation
Correct Answer
Voice or business transactions follow eligible links meeting their defined SLA while bulk traffic uses permitted alternatives without starving priority services. This is the operational validation outcome rather than merely an enabled setting. A link showing the highest bandwidth is not necessarily the best choice for latency-sensitive traffic, and SD-WAN SLA measurements must match actual critical paths. Scenario: An engineer changes a latency rule but the old long-lived sessions remain pinned to their previous SD-WAN member, confusing validation results.
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: Voice or business transactions follow eligible links meeting their defined SLA while bulk traffic uses permitted alternatives without starving priority services. Scenario: An engineer changes a latency rule but the old long-lived sessions remain pinned to their previous SD-WAN member, confusing validation results.
An impaired member is correctly classified and a tested policy change restores traffic without hiding intermittent loss or creating new path asymmetry. This result would test SD-WAN diagnostics, route changes and link-quality evidence but does not demonstrate the desired FortiGate outcome here. Verify instead: Voice or business transactions follow eligible links meeting their defined SLA while bulk traffic uses permitted alternatives without starving priority services. Scenario: An engineer changes a latency rule but the old long-lived sessions remain pinned to their previous SD-WAN member, confusing validation results.
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: Voice or business transactions follow eligible links meeting their defined SLA while bulk traffic uses permitted alternatives without starving priority services. Scenario: An engineer changes a latency rule but the old long-lived sessions remain pinned to their previous SD-WAN member, confusing validation results.
