Free CompTIA CySA+ CS0-003 Practice Question
A security analyst observes that the processor utilization on a server spikes to 95-100% at intermittent periods throughout the workday when typical usage previously averaged around 40%.

Review the task manager or resource monitor to identify high-CPU-usage processes.
Check for pending operating system updates or failed update installations.
Verify network throughput to rule out excessive traffic as a cause for high CPU usage.
Run a full antivirus scan on the server to search for any infections.
