An administrator is troubleshooting a CPU issue for a virtual machine. The following is seen in esxtop:
CPU0 is at 100% usage
The remaining logical CPUs are close to 0%
%RDY value is consistently above 10%
What is likely the cause of the CPU issue?
A. The virtual machine has a CPU limit configured.
B. The virtual machine’s guest operating system is configured for SMP.
C. The virtual machine has CPU affinity configured.
D. The virtual machine is configured with a CPU reservation.
Correct Answer: C

Explanation:
Using CPU Affinity
By specifying a CPU affinity setting for each virtual machine, you can restrict the assignment of virtual machines to a subset of the available processors in multiprocessor systems. By using this feature, you can assign each virtual machine to processors in the specified affinity set.
CPU affinity specifies virtual machine-to-processor placement constraints and is different from the relationship created by a VM-VM or VM-Host affinity rule, which specifies virtual machine-to-virtual machine host placement constraints.
