XK0-006 Practice Question: A junior administrator needs to monitor system…
A junior administrator needs to monitor system resource usage on a production server. Which TWO commands should the administrator use to check CPU and memory utilization in real-time? (Choose two.)
⚠ Common exam trap
The Linux+ exam often tests the distinction between commands that show real-time resource usage versus those that show static or historical data, and the trap here is that candidates might choose `uptime` thinking it shows CPU utilization, when it only shows load averages.
