Question 30
At Highland Education, the education network defense team administers FortiGate-based protection for online learning networks and regional offices under requirements for protected student services and remote connectivity. An independent validation is requested for: A newly deployed FortiGate cannot resolve FortiGuard service names even though it has an otherwise valid internet default route. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
FortiGate diagnostic resolution returns supported service addresses and FortiGuard connectivity succeeds without changing unrelated firewall rules. This outcome validates the intended correction for: A newly deployed FortiGate cannot resolve FortiGuard service names even though it has an otherwise valid internet default route. The associated approved corrective action is: Configure reliable system DNS resolvers and verify the FortiGate local-out DNS path independently of client forwarding policies. The Highland Education reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The cloud service reports the intended CNF integration and policy controls without requiring an unsupported manual appliance attachment. This would verify a separate corrective action: Select the documented FortiGate CNF service workflow for the supported cloud provider and keep VM deployments as a distinct model. That separate change addresses: A security team conflates FortiGate Cloud-Native Firewall with manually managing a general-purpose FortiGate VM and chooses the wrong onboarding workflow. It does not validate the current Highland Education issue: A newly deployed FortiGate cannot resolve FortiGuard service names even though it has an otherwise valid internet default route. The relevant acceptance evidence is: FortiGate diagnostic resolution returns supported service addresses and FortiGuard connectivity succeeds without changing unrelated firewall rules.
The corrected cluster displays the documented primary and secondary roles with healthy heartbeat paths and no policy changes made blindly. This would verify a separate corrective action: Inspect HA status, uptime, priorities, override and monitored-interface health to identify the actual election cause. That separate change addresses: An HA cluster shows an unexpected primary member after startup, but engineers change traffic policies instead of diagnosing heartbeat and election state. It does not validate the current Highland Education issue: A newly deployed FortiGate cannot resolve FortiGuard service names even though it has an otherwise valid internet default route. The relevant acceptance evidence is: FortiGate diagnostic resolution returns supported service addresses and FortiGuard connectivity succeeds without changing unrelated firewall rules.
HA diagnostics show synchronized configurations and the standby node contains the intended policy after the supported sync operation. This would verify a separate corrective action: Investigate HA checksums, heartbeat status and supported configuration synchronization prerequisites before applying the change again. That separate change addresses: A firewall change made on the primary FGCP node never reaches the other node because HA configuration synchronization reports an error. It does not validate the current Highland Education issue: A newly deployed FortiGate cannot resolve FortiGuard service names even though it has an otherwise valid internet default route. The relevant acceptance evidence is: FortiGate diagnostic resolution returns supported service addresses and FortiGuard connectivity succeeds without changing unrelated firewall rules.
