Question 480
At Oakridge Public Services, the municipal network protection team administers FortiGate-based protection for citizen services and remote public offices under requirements for restricted data exchange and defensible access policy. An independent validation is requested for: FortiGate cannot categorize web requests because its FortiGuard rating connectivity or licensing is unavailable and operators treat the problem as an access-list error. Which observed outcome BEST demonstrates that the intended correction works?
Explanation
Correct Answer
The firewall successfully retrieves category ratings and logs the intended classification decision for a controlled destination. This outcome validates the intended correction for: FortiGate cannot categorize web requests because its FortiGuard rating connectivity or licensing is unavailable and operators treat the problem as an access-list error. The associated approved corrective action is: Verify service registration, rating server connectivity and supported fail-behavior settings before adjusting local web rules. The Oakridge Public Services reviewer can therefore distinguish observable protection from an untested configuration claim.
Incorrect Answers
The event identifies the effective IPS action for the specific signature and a subsequent approved sensor change behaves consistently. This would verify a separate corrective action: Inspect the matched firewall policy, assigned IPS sensor and signature override precedence for the controlled traffic. That separate change addresses: A large policy estate duplicates different IPS sensors with conflicting overrides and an engineer cannot determine which one applied to a particular connection. It does not validate the current Oakridge Public Services issue: FortiGate cannot categorize web requests because its FortiGuard rating connectivity or licensing is unavailable and operators treat the problem as an access-list error. The relevant acceptance evidence is: The firewall successfully retrieves category ratings and logs the intended classification decision for a controlled destination.
The offending workload is identified and CPU falls after a targeted safe sensor adjustment while core IPS checks remain active. This would verify a separate corrective action: Correlate IPS engine resource metrics, relevant session rates and signature processing before tuning the sensor scope. That separate change addresses: A FortiGate IPS scan reports high CPU but administrators cannot distinguish inspection workload from unrelated system processes. It does not validate the current Oakridge Public Services issue: FortiGate cannot categorize web requests because its FortiGuard rating connectivity or licensing is unavailable and operators treat the problem as an access-list error. The relevant acceptance evidence is: The firewall successfully retrieves category ratings and logs the intended classification decision for a controlled destination.
An authorized ordinary DNS resolution succeeds and a controlled disallowed encrypted-DNS client is blocked or explicitly audited. This would verify a separate corrective action: Evaluate supported application-control signatures or managed endpoint controls to restrict unauthorized encrypted DNS services. That separate change addresses: An application starts using encrypted DNS-over-HTTPS to evade approved DNS filtering and the firewall does not recognize its traffic type. It does not validate the current Oakridge Public Services issue: FortiGate cannot categorize web requests because its FortiGuard rating connectivity or licensing is unavailable and operators treat the problem as an access-list error. The relevant acceptance evidence is: The firewall successfully retrieves category ratings and logs the intended classification decision for a controlled destination.
