An engineer received an alert affecting the degraded performance of a critical server. Analysis showed a heavy CPU and memory load. What is the next step the engineer should take to investigate this resource usage?
A.
Run "ps -d" to decrease the priority state of high load processes to avoid resource exhaustion.
B.
Run "ps -u" to find out who executed additional processes that caused a high load on a server.
C.
Run "ps -ef" to understand which processes are taking a high amount of resources.
D.
Run "ps -m" to capture the existing state of daemons and map required processes to find the gap.
The “ps” command is used to display information about the processes running on a system. The “-ef” option shows the full format listing, which includes the process ID, the user, the CPU and memory usage, the command name, and other details. This can help the engineer identify which processes are consuming the most resources and causing the degraded performance of the server. The other options are either invalid or irrelevant, as they do not provide the necessary information or perform the required action. References := Cisco Cybersecurity
