Q4. 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.

A. Set the Advanced Parameter numa.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.
