A. A CPU hour is a unit of measurement that indicates the number of hours a CPU core has been actively processing data.

A CPU hour is calculated by multiplying the number of CPU cores used by the number of hours that they were active. For example, using 16 cores for 1 hour would equate to 16 CPU hours.
