Objective 4.1

220-1201

Explain virtualization concepts.

Objective 4.1 sits in Virtualization and Cloud Computing, which carries 11% of the A+ Core 1 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

4-1Virtualization and Cloud Computing

A technician needs to explain how Hyper-V achieves near-native performance and strong isolation for virtual machines. Which hypervisor type does Hyper-V use?

A container engine that shares the host operating system kernelA container engine virtualizes at the OS level and shares a kernel, unlike a hypervisor.
A type 2 hypervisor that runs as an application inside a host OSA type 2 hypervisor runs inside a host OS, which is the opposite of how Hyper-V is described.
A bare metal emulator that translates instructions for legacy appsAn emulator translates instructions between architectures, which is not how Hyper-V's hypervisor layer is described.
A type 1 hypervisor that runs directly on the physical hardwareCorrect · your answerCorrect: this matches how Hyper-V is described running directly on hardware.
A cloud orchestration tool that provisions virtual machinesAn orchestration tool manages VM deployment but is not itself the hypervisor layer.

Correct.

Concept

Where a hypervisor sits in the stack decides what it has to trust. One that owns the hardware outright has no general-purpose operating system beneath it to be compromised, scheduled around, or patched on someone else's timetable.

Why D

Running directly on computing hardware is exactly what makes a hypervisor type 1, and this is what gives Hyper-V near-native performance and strong isolation.

Source

As a type-1 hypervisor, Hyper-V runs directly on computing hardware, delivering near-native performance and robust isolation for virtualized workloads.

Sample question 1 of 3

4-1Virtualization and Cloud Computing

An organization wants to give many employees full Windows desktops while running fewer virtual machines and reducing operating system overhead. Which Azure Virtual Desktop capability directly supports this goal?

Sample question 2 of 3

4-1Virtualization and Cloud Computing

A retail company's virtual desktop environment automatically adds session host capacity during a holiday sales spike and removes it once traffic returns to normal. Which cloud computing characteristic does this describe?

Sample question 3 of 3

4-1Virtualization and Cloud ComputingChoose 2

A company's autoscale policy shrinks host pool capacity overnight, and its monthly invoice reflects only the compute hours actually consumed by session hosts. Which two cloud computing concepts are both illustrated?
