In a computer science class, Benjamin is learning about virtualization technologies. He comes across a term that describes a hypervisor that runs directly on the hardware without needing a host operating system. What is this Type 1 hypervisor also known as?
Bare-metal hypervisor
Host-based hypervisor
Virtual machine manager
Emulated hypervisor
In a classroom, David is frustrated because he always has to install updates for the software he uses for his projects. Charlotte suggests a method that ensures applications are always up-to-date for users like David. What virtualization method is she referring to?
Server-side virtualization
Application virtualization
Client-side virtualization
Container virtualization
Liam is managing a virtual machine on a hypervisor, but he notices that its performance is poor. What could be causing this issue?
Virtual network misconfiguration
Insufficient system memory on the host
Dynamic disk image expansion
SLAT disabled in CPU firmware
Nora is setting up a new project and needs to use cloud services to host her application. She wants to have on-demand infrastructure, such as virtual servers and storage, but she is willing to manage the operating system and applications herself. Which cloud service model should she choose?
SaaS
IaaS
PaaS
Hybrid Cloud
In a school where Ava, Arjun, and Rohan are students, what is the primary purpose of Virtual Desktop Infrastructure (VDI)?
To enable thin clients to process data locally
To provision desktops as virtual machines on a centralized server
To replace virtualization servers with high-end desktops
To run multiple OSs on a single physical desktop

In a computer lab, Avery is trying to understand what a virtual machine (VM) is. She learns that it can be described as which of the following?
A physical hardware system managed by a hypervisor
A hypervisor that runs on a server
A guest operating system running under a hypervisor
A network management tool
Luna is working on a virtual machine for her project and wants to ensure she can revert to a previous state if something goes wrong. What is the benefit of using snapshots in virtualization?
Snapshots expand storage dynamically.
Snapshots allow a rollback to a previous VM state.
Snapshots increase virtual network performance.
Snapshots reduce system memory usage.
