Question

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?

Options

  • ASet the Advanced Parameter numa.vcpu.preferHT = TRUE in the virtual machine configuration
  • BSet the Advanced Parameter numa.vcpu.preferHT = FALSE in the virtual machine configuration
  • CSet the Advanced Parameter numa.PreferHT = 1 in the ESXi host configuration file.
  • DSet the Advanced Parameter numa.PreferHT = 0 in the ESXi host configuration file.
