An administrator wants to select a Host Power Management Policy for an ESXi 6.x host that will disable most hardware power management features. Which Host Power Management Policy should be selected to

The correct answer is A. High Performance. The High Performance Host Power Management Policy in ESXi disables most hardware power management features, preventing the CPU from entering low-power states and maximizing processing performance.

Why each option

The High Performance Host Power Management Policy in ESXi disables most hardware power management features, preventing the CPU from entering low-power states and maximizing processing performance.

AHigh PerformanceCorrect

The High Performance policy instructs ESXi to disable processor power-saving states such as C-states and P-states along with other hardware power management features, ensuring CPUs run at full frequency without throttling - this matches the requirement to disable most hardware power management features.

BBalanced

Balanced policy allows ESXi to selectively engage hardware power management features to reduce energy consumption while limiting performance impact, meaning hardware power management is not disabled.

CLow Power

Low Power policy aggressively enables hardware power management features to minimize energy use, which is the opposite of disabling them.

DDisabled

Disabled policy prevents ESXi from modifying BIOS power management settings entirely, ceding control to the BIOS rather than actively disabling hardware power management features from within ESXi.
