A system administrator needs to monitor resource usage and performance in real time to identify a process that is consuming an unusually high percentage of CPU resources. Which of the following commands provides the BEST solution for this requirement?
cat /proc/cpuinfo
ps aux --sort -%cpu
top
pscat
The 'top' command is the correct answer because it displays a real-time view of system processes, including CPU usage, memory consumption, and other important metrics. By using 'top', the administrator can easily identify processes that are using a high percentage of CPU resources. Other commands listed either do not provide real-time monitoring, or they address different aspects of system management.
