4.2 Summarize cloud computing concepts.
Objective 4.2 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.

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?
The concept
Hypervisor architecture determines how closely a virtual machine's performance and isolation match the underlying hardware.
Why this answer
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.
- Correct: this describes running directly on hardware with near native performance and isolation.
- BA type-2 hypervisor runs on top of a host operating system, adding overhead the scenario does not describe.
- CAn emulator translates instructions between architectures and is not what provides near native performance here.
- DA container runtime virtualizes at the OS level and shares the kernel, unlike a full hypervisor.
Now you: objective 4.2 questions
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.
