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 power policy in ESXi disables most hardware power management features so the host can deliver maximum CPU performance without throttling or frequency scaling.

Why each option

The High Performance power policy in ESXi disables most hardware power management features so the host can deliver maximum CPU performance without throttling or frequency scaling.

AHigh PerformanceCorrect

High Performance instructs ESXi to disable processor power states (C-states) and P-state transitions, preventing the CPU from throttling down, which disables most hardware power management features as stated in the requirement.

BBalanced

Balanced allows ESXi to use power management features when load is low, so hardware power management remains partially active.

CLow Power

Low Power aggressively enables power management features to reduce energy consumption, which is the opposite of the requirement.

DDisabled

Disabled turns off ESXi's own power management control but leaves hardware and BIOS power management active, meaning hardware power features are not necessarily disabled.
