A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
Which term describes a hypervisor that runs directly on physical computing hardware rather than inside a host operating system, giving virtual machines near native performance and strong isolation?
Correct.
Checked against learn.microsoft.com, July 2026Concept
Hypervisor architecture determines how closely a virtual machine's performance and isolation match the underlying hardware.
Why A
A hypervisor installed directly on hardware, without a host operating system layer in between, is classified as a type-1 hypervisor and delivers near native performance with strong isolation.

No account needed. The explanation opens when you answer.
Sample question 1 of 3
A systems administrator consolidates ten physical servers onto one Hyper-V host, running each former server as a separate guest virtual machine that draws from the host's shared CPU, memory, and storage. Which cloud computing concept does this illustrate?
Sample question 2 of 3
An Azure Virtual Desktop administrator sets up autoscale so extra session host virtual machines start each weekday morning and shut down overnight as demand drops. Which cloud computing concept is being applied?
Sample question 3 of 3
A company assigns most employees to pooled, multi-session Azure Virtual Desktop host pools so many users share the same virtual machines, while executives receive personal, persistent desktops for individual ownership. Which term specifically describes the multi-session configuration used for employees?
That’s 3 of the full A+ Core 1 bank.
