An administrator is troubleshooting a performance problem with a virtual machine (VM). The VM and ESXi host configuration is as follows:

The application which runs within the virtual machine is highly sensitive to memory latency, but
has low processor utilization.
The virtual machine has 6 vCPUs.
The ESXi host CPU topology has 2 Physical CPU Sockets, each with 8 Logical CPUs.
The ESXi host CPU has Hyper Threading enabled.
The administrator would like to improve CPU performance for this VM. Other VMs on the host
have no performance issues. Which action should the administrator take to resolve the issue?

 
A.Set the Advanced Parameternuma.vcpu.preferHT = TRUE in the virtual machine configuration file.
B.Set the Advanced Parameter numa.vcpu.preferHT = FALSE in the virtual machine configuration
file.
C.Set the Advanced Parameter numa.PreferHT = 1 in the ESXi host configuration file.
D.Set the Advanced Parameter numa.PreferHT = 0 in the ESXi host configuration file.
