Which command displays CPU utilization?

B

The correct command to display CPU utilization on Cisco devices is "show processes". Therefore, the correct answer is B.

The "show processes" command displays information about active processes on the device, including CPU utilization statistics. By default, the output will show the top five processes consuming the most CPU resources, along with their process ID (PID), status, and utilization percentage.

For example, the output of the "show processes" command might look like this:

Router# show processes CPU utilization for five seconds: 35%/10%; one minute: 45%; five minutes: 50% PID   Runtime(ms)   Invoked      uSecs    5Sec    1Min    5Min  TTY  Process ---   -----------   -------   ---------   -----   -----   -----  ---  -------   1           312         1         312   0.00%   0.00%   0.00%   0   Chunk Manager   2          4164       292          14   0.00%   0.00%   0.00%   0   Load Meter   3           220       174           1   0.00%   0.00%   0.00%   0   IPC Periodic Tim   4        546688   1198793          45  22.61%  17.52%  16.83%   0   IP Input   5           244         1         244   0.00%   0.00%   0.00%   0   Ethernet Msec Ti 

In this example, the CPU utilization for the past five seconds is 35%, while the CPU utilization for the past one minute and five minutes is 45% and 50%, respectively. The top CPU-consuming process is process ID 4 (IP Input), which has consumed 22.61% of the CPU resources in the past five seconds.

Note that the "show system" command displays system-wide information, but not CPU utilization specifically. The "show protocols" command displays information about configured protocols, while the "show version" command displays information about the device's software version and hardware platform.
