A vSphere administrator needs to add a CPU to a virtual machine, but upon editing the VM settings the option is grayed out.
What would explain this behavior?
A. The virtual machine is running
B. The virtual machine has been configured with a CPU limit
C. CPU Hot-add has not been enabled on the virtual machine
D. The virtual machine is in a resource pool with no available CPU resources
Correct Answer: AC
Explanation/Reference:
Explanation:
CPU Hot-add is not enabled by default. To enable it, the VM must be powered off. This will enable you to add a CPU while the VM is running. To add a CPU without using the CPU Hot-add feature, the VM must be powered off.
Incorrect Answers:
B: The CPU limit is configured via resource allocation. This will not result in the option being grayed out in the VM settings.
D: Even if the virtual machine is in a resource pool with no available CPU resources, will not result in the option being grayed out in the VM settings.
