Question 460
A FortiOS 7.6 team examines: A previously permitted software site changes classification and access failures need evidence. 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 previously permitted software site changes classification and access failures need evidence. The targeted administrative response is: Correlate the matched firewall policy, applied web-filter profile, user identity and observed rating to diagnose unexpected web access. The relevant failure risk is: An apparent web-filter failure can arise from a different matched policy or an authentication group mismatch. Validate with: Web-filter and traffic events identify which identity, category and policy produced the blocked or allowed result.
For the observed situation (A previously permitted software site changes classification and access failures need evidence), the most specific acceptance evidence is: Web-filter and traffic events identify which identity, category and policy produced the blocked or allowed result. It validates the recommended response: Correlate the matched firewall policy, applied web-filter profile, user identity and observed rating to diagnose unexpected web access. This addresses the documented risk: An apparent web-filter failure can arise from a different matched policy or an authentication group mismatch.
Incorrect Answers
Ips resource pressure and measurement (3.5) would demonstrate or implement: Disabling IPS during high CPU without a constrained diagnosis can leave mission-critical services unprotected. The case states: A previously permitted software site changes classification and access failures need evidence. The most direct paired action and test is: Correlate the matched firewall policy, applied web-filter profile, user identity and observed rating to diagnose unexpected web access.
Application signatures and false-positive review (3.3) would demonstrate or implement: A targeted approved application completes while an unauthorized signature test remains blocked after the adjustment. This case instead tests Web-filter authentication and policy mismatch diagnosis; the choice measures or changes another part of the system.
Certificate inspection visibility versus decrypted inspection (3.1) addresses another technical failure: Certificate-only inspection cannot inspect arbitrary encrypted application payload content for threats. The paired-answer requirement concerns Web-filter authentication and policy mismatch diagnosis; this alternative does not provide the matching intervention and separate acceptance evidence.
