An administrator is building a large virtual machine that will require as many vCPUs as the host can support. An ESXi 6.x host has these specifications: Four 24-core Intel Xeon Processors 256 GB of…

64 vCPUs is well below both the ESXi 6.x per-VM limit and the physical core count, and does not represent the maximum the platform supports.

96 matches the number of physical cores on the host but ignores ESXi's ability to over-provision vCPUs beyond physical cores and is not the documented per-VM maximum.

ESXi 6.x supports a maximum of 128 vCPUs per virtual machine as a platform-defined limit. Although the host has 4 x 24 = 96 physical cores (192 logical with hyperthreading enabled), the VM cannot be allocated more than 128 vCPUs - the per-VM ceiling imposed by ESXi 6.x is the binding constraint, not the physical core count.

192 matches the logical processor count with hyperthreading enabled, but ESXi 6.x enforces a hard per-VM cap of 128 vCPUs, making 192 an invalid allocation.
