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.
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.
Balanced allows ESXi to use power management features when load is low, so hardware power management remains partially active.
Low Power aggressively enables power management features to reduce energy consumption, which is the opposite of the requirement.
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.
