Question 580
A FortiOS 7.6 team examines: A performance tuning change should preserve high-severity exploit protection on a critical server policy. 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 performance tuning change should preserve high-severity exploit protection on a critical server policy. The targeted administrative response is: Correlate IPS sensor configuration, signature workload and CPU usage before changing inspection scope or firewall capacity. The relevant failure risk is: Disabling IPS during high CPU without a constrained diagnosis can leave mission-critical services unprotected. Validate with: Comparative resource sampling shows acceptable CPU and the approved IPS tests still produce expected actions.
For the observed situation (A performance tuning change should preserve high-severity exploit protection on a critical server policy), the most specific acceptance evidence is: Comparative resource sampling shows acceptable CPU and the approved IPS tests still produce expected actions. It validates the recommended response: Correlate IPS sensor configuration, signature workload and CPU usage before changing inspection scope or firewall capacity. This addresses the documented risk: Disabling IPS during high CPU without a constrained diagnosis can leave mission-critical services unprotected.
Incorrect Answers
TLS inspection exceptions and sensitive traffic (3.1) would demonstrate or implement: Approved sensitive flows work under narrow exclusions while ordinary eligible web traffic remains inspected. The case states: A performance tuning change should preserve high-severity exploit protection on a critical server policy. The most direct paired action and test is: Correlate IPS sensor configuration, signature workload and CPU usage before changing inspection scope or firewall capacity.
Application monitoring versus blocking (3.3) addresses another technical failure: Confusing a monitor-only action with an enforcement action can leave a prohibited application available. This case instead tests Ips resource pressure and measurement; the choice measures or changes another part of the system.
Application control signature matching (3.3) would demonstrate or implement: A generic port allow does not distinguish approved from prohibited applications sharing encrypted or common ports. The paired-answer requirement concerns Ips resource pressure and measurement; this alternative does not provide the matching intervention and separate acceptance evidence.
