The correct answer is B. Average ESXi highest latency, in milliseconds C. Average virtual machine operating system latency per command, in milliseconds. When the storage array is performing poorly or became a bottleneck, you will see the average ESXi highest latency in milliseconds. Moreover, the average virtual machine operation system latency per command will be high in milliseconds.

Options

AAverage ESXi VMKernel latency per command, in milliseconds
BAverage ESXi highest latency, in milliseconds
CAverage virtual machine operating system latency per command, in milliseconds
DNumber of SCSI reservation conflicts per second
