Which process could be used to increase compute resources to a virtual machine (VM) without first
powering down?
A.
Increase the CPU Share value on the VM.
B.
vMotion the VM to an ESXi host with greater CPU capacity.
C.
Add a vCPU to the VM using CPU hot add.
D.
Move the VM into a Resource Pool with a larger CPU resource allocation.
A

not sure for answer (D or A ) , but for sure C does not require a VM shutdown (Hot add components – CPU and Memory)

C = to add more compute resources, using CPU Hot add can only enabled if the virtual machine is TURNED OFF or POWERED DOWN

C is not the answer here

Zach in your own link it says pretty clear:
“You can now add CPUs even if the virtual machine is turned on.”
So it looks like hot add works on machine that is running (don’t confuse with hot plug)

But the answer is saying that you can do it with “hot add” where as the link says that it can be done using “hot plug”. I have a hard time saying that it is C simply because of verbiage.

But C would only be valid if “CPU Hot Add” is already enabled. If not you have to first power down, enable that option and then you can add cpus online
