CPU and Memory Thresholding
One of the ways to monitor whether an attack is occurring on a device is through the simple
monitoring of device resources, including CPU and memory utilization. This is done
by configuring the use of CPU or memory threshold monitoring. Both of these features
can be combined with a remote management server to notify an organization when the
CPU and memory conditions on a device become critical.
I think answer c is correct
The question asks: CONFIGURABLE Cisco IOS feature.
