Question 120
A FortiOS 7.6 team examines: A security analyst needs evidence that a CPU reduction follows a targeted policy change rather than lower traffic. 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 security analyst needs evidence that a CPU reduction follows a targeted policy change rather than lower traffic. The targeted administrative response is: Correlate FortiGate CPU utilization, busy processes, enabled security inspection and traffic changes before choosing a remediation. The relevant failure risk is: Restarting a device or disabling inspection without finding the resource consumer can hide a repeatable overload. Validate with: Sampled resource metrics identify a cause and demonstrate lower CPU under a comparable authorized traffic load.
For the observed situation (A security analyst needs evidence that a CPU reduction follows a targeted policy change rather than lower traffic), the most specific acceptance evidence is: Sampled resource metrics identify a cause and demonstrate lower CPU under a comparable authorized traffic load. It validates the recommended response: Correlate FortiGate CPU utilization, busy processes, enabled security inspection and traffic changes before choosing a remediation. This addresses the documented risk: Restarting a device or disabling inspection without finding the resource consumer can hide a repeatable overload.

Targeted traffic and event log diagnosis (1.2) addresses another technical failure: Guessing from a high-level allow counter can miss an explicit deny, policy mismatch or missing logging configuration. This choice can be useful for that problem, but it does not establish the High cpu and process-focused diagnosis control being assessed here.
Fortigate dhcp service and subnet scope (1.1) would demonstrate or implement: A test client on the approved VLAN receives the intended lease, gateway and DNS servers without duplicate assignments. This case instead tests High cpu and process-focused diagnosis; the choice measures or changes another part of the system.
Fgcp management interface separation (1.3) would demonstrate or implement: Relying only on the shared cluster management address can block direct diagnosis of an offline or standby member. The paired-answer requirement concerns High cpu and process-focused diagnosis; this alternative does not provide the matching intervention and separate acceptance evidence.
