Question 680
A FortiOS 7.6 team examines: A new overlay WAN member has correct health but no valid route to the intended remote destination. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.
Explanation
Correct Answers
For the observed situation (A new overlay WAN member has correct health but no valid route to the intended remote destination), the most specific acceptance evidence is: A test flow records the expected SD-WAN rule, selected member, eligible route and firewall policy. It validates the recommended response: Check SD-WAN service-rule order, route availability and firewall policy together when traffic does not follow intended member steering. This addresses the documented risk: A matching SD-WAN rule cannot guarantee a working connection if candidate routes or the zone firewall policy are absent.
The reported FortiOS 7.6 condition is: A new overlay WAN member has correct health but no valid route to the intended remote destination. The targeted administrative response is: Check SD-WAN service-rule order, route availability and firewall policy together when traffic does not follow intended member steering. The relevant failure risk is: A matching SD-WAN rule cannot guarantee a working connection if candidate routes or the zone firewall policy are absent. Validate with: A test flow records the expected SD-WAN rule, selected member, eligible route and firewall policy.
Incorrect Answers
Static route next-hop reachability (4.1) would demonstrate or implement: A route to an unreachable next hop can blackhole permitted packets even when its configuration appears syntactically valid. This choice can be useful for that problem, but it does not establish the Sd-wan rule order and route interaction control being assessed here.
Equal-cost route redundancy and path verification (4.1) would demonstrate or implement: Controlled client tests demonstrate permitted traffic distribution and recovery after one approved path becomes unavailable. The required paired action and test concerns Sd-wan rule order and route interaction; a passing result for this alternative could leave that requirement unresolved.
Longest-prefix match and route lookup (4.1) addresses another technical failure: A broad default route cannot override an installed more-specific matching prefix solely because its interface is healthy. The paired-answer requirement concerns Sd-wan rule order and route interaction; this alternative does not provide the matching intervention and separate acceptance evidence.
