NSE7 Troubleshooting and Diagnostics Practice Question
A FortiGate administrator wants to check if the device is experiencing high CPU usage due to a specific process. Which command should they use to display real-time process CPU usage?
⚠ Common exam trap
Test-takers frequently confuse 'show system resource' (overall stats) with per-process diagnostics, or they mistakenly think 'get system performance status' provides process-level detail, when it only shows aggregate performance metrics.
