Question 630
A FortiOS 7.6 team examines: A branch changes routing and an established policy now matches a different outgoing interface zone. Select TWO complementary choices: the most appropriate corrective action AND the specific evidence confirming success.
Explanation
Correct Answers
For the observed situation (A branch changes routing and an established policy now matches a different outgoing interface zone), the most specific acceptance evidence is: Traffic logs and route diagnostics show both the intended route and an approved first-match firewall policy. It validates the recommended response: Diagnose routing eligibility, outgoing interface, firewall policy and NAT as separate required decisions for a FortiGate connection. This addresses the documented risk: A successful route lookup does not itself authorize a packet, and an allow rule does not create a missing return route.
The reported FortiOS 7.6 condition is: A branch changes routing and an established policy now matches a different outgoing interface zone. The targeted administrative response is: Diagnose routing eligibility, outgoing interface, firewall policy and NAT as separate required decisions for a FortiGate connection. The relevant failure risk is: A successful route lookup does not itself authorize a packet, and an allow rule does not create a missing return route. Validate with: Traffic logs and route diagnostics show both the intended route and an approved first-match firewall policy.
Incorrect Answers
Sd-wan performance sla probes (4.2) addresses another technical failure: An unreachable or unsuitable probe target can make a healthy WAN look failed or fail to detect real application degradation. The case states: the most appropriate corrective action AND the specific evidence confirming success. The most direct paired action and test is: Traffic logs and route diagnostics show both the intended route and an approved first-match firewall policy.
Sd-wan members and zones (4.2) would demonstrate or implement: An omitted WAN member or wrong zone can prevent an uplink from participating even while the physical port is operational. This choice can be useful for that problem, but it does not establish the Routing versus firewall policy separation control being assessed here.
Sd-wan rule order and route interaction (4.2) would demonstrate or implement: A test flow records the expected SD-WAN rule, selected member, eligible route and firewall policy. The paired-answer requirement concerns Routing versus firewall policy separation; this alternative does not provide the matching intervention and separate acceptance evidence.
