- What is a hypervisor?
Show answer
Software that creates and manages virtual machines by abstracting physical hardware resources.- What is a Type 1 hypervisor?
Show answer
A hypervisor that runs directly on hardware without requiring a host operating system.- What is a Type 2 hypervisor?
Show answer
A hypervisor that runs as an application on top of a host operating system.- Name three examples of Type 1 hypervisors.
Show answer
ESXi, Hyper-V, and KVM.- Name two examples of Type 2 hypervisors.
Show answer
VirtualBox and VMware Workstation.- What is the main performance advantage of Type 1 hypervisors over Type 2?
Show answer
Type 1 has less overhead because it runs directly on hardware without a host OS layer.- What is a virtual machine (VM)?
Show answer
An emulated computer that runs on physical hardware controlled by a hypervisor.- What is a VM snapshot?
Show answer
A point-in-time copy of a virtual machine's state, including all disk and memory contents.- What is the primary use case for VM snapshots?
Show answer
To enable quick rollback to a previous state if something goes wrong after a change.- What is a vCPU?
Show answer
A virtual CPU allocated to a virtual machine from the physical processor.- What is vRAM?
Show answer
Virtual random access memory allocated to a virtual machine from the physical memory pool.- What is live migration?
Show answer
Moving a running virtual machine from one physical host to another without stopping it.- What is a key benefit of live migration?
Show answer
Zero or minimal downtime, as the VM continues running during the transfer to the new host.- What is a VM template?
Show answer
A master copy of a virtual machine configured with an operating system and applications, used to create new VMs.- What is VM cloning?
Show answer
The process of creating an exact copy of a virtual machine from a template or existing VM.
