Which statement best applies to virtual CPUs?

In AIX, the number of virtual CPUs assigned to a Logical Partition (LPAR) determines its potential access to CPU resources. Virtual CPUs represent the CPU capacity that the LPAR can use, but they rely on physical CPUs to process workloads. The more virtual CPUs an LPAR has, the greater its access to CPU time, but they must be backed by physical CPU resources.References:= IBM AIX Documentation
