Question 610
A FortiOS 7.6 team examines: A route looks correct in the configuration export but never becomes eligible for use after an interface goes down. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.
Explanation
Correct Answers
The reported FortiOS 7.6 condition is: A route looks correct in the configuration export but never becomes eligible for use after an interface goes down. The targeted administrative response is: Check the static route destination, outgoing interface and reachable next-hop gateway before altering policy or NAT. The relevant failure risk is: A route to an unreachable next hop can blackhole permitted packets even when its configuration appears syntactically valid. Validate with: A bounded trace and route lookup show the gateway is reachable and the authorized flow leaves by the intended interface.
For the observed situation (A route looks correct in the configuration export but never becomes eligible for use after an interface goes down), the most specific acceptance evidence is: A bounded trace and route lookup show the gateway is reachable and the authorized flow leaves by the intended interface. It validates the recommended response: Check the static route destination, outgoing interface and reachable next-hop gateway before altering policy or NAT. This addresses the documented risk: A route to an unreachable next hop can blackhole permitted packets even when its configuration appears syntactically valid.

Sd-wan health failover and session evidence (4.2) would demonstrate or implement: The intended new sessions recover on healthy members and the test documents behavior of established flows. The case states: A route looks correct in the configuration export but never becomes eligible for use after an interface goes down. The most direct paired action and test is: Check the static route destination, outgoing interface and reachable next-hop gateway before altering policy or NAT.
Sd-wan performance sla probes (4.2) would demonstrate or implement: An unreachable or unsuitable probe target can make a healthy WAN look failed or fail to detect real application degradation. The required paired action and test concerns Static route next-hop reachability; a passing result for this alternative could leave that requirement unresolved.
Sd-wan best-quality application steering (4.2) addresses another technical failure: A generic load-balancing rule can send latency-sensitive sessions through poor-quality links if no app-specific strategy wins. The paired-answer requirement concerns Static route next-hop reachability; this alternative does not provide the matching intervention and separate acceptance evidence.
