Question 1

What is a Type 1 hypervisor and on what does it run directly?

Accepted Answer

A Type 1 hypervisor (bare-metal) runs directly on the host hardware without a host OS underneath it. Examples include VMware ESXi and Microsoft Hyper-V Server.

Question 2

What is a Type 2 hypervisor and how does it differ from a Type 1?

Accepted Answer

A Type 2 hypervisor runs as an application on top of a host operating system. Unlike Type 1, it depends on the host OS for hardware access. Examples include VirtualBox and VMware Workstation.

Question 3

What CPU feature must be enabled in BIOS/UEFI to support hardware-assisted virtualization on Intel processors?

Accepted Answer

Intel Virtualization Technology (Intel VT-x) must be enabled in BIOS/UEFI. Without it, the hypervisor cannot run 64-bit virtual machines or may not function at all.

Question 4

What is the term for the ability to move a running virtual machine from one physical host to another with no downtime?

Accepted Answer

Live migration (also called vMotion in VMware environments) allows a running VM to be transferred between hosts without interrupting the guest OS or its services.

Question 5

What is a VM snapshot used for?

Accepted Answer

A VM snapshot captures the exact state, data, and configuration of a virtual machine at a specific point in time. It allows administrators to quickly revert the VM to that saved state if needed.
