B) Hypervisor

In a virtualized environment, what technology is used to run the virtual machines? A) Sandbox B) Hypervisor C) Virtual Host Machine (VHM) D) vHost

Emulator

In computing, an _________ is hardware or software that enables one computer system (called the host) to behave like another computer system (called the guest). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system

Virtual Network Interface Cards (vNIC)

____________ are used to route traffic to each virtual host without sending network traffic to all hosts on a server. This is important because cloud providers typically place many customer's virtual servers on the same physical server (Resource Pooling).

VM, emulator

a ____________ is designed to create an isolated environment, whereas an _____________ is designed to reproduce the behavior of some type of hardware and/or firmware.

LXD

a hypervisor that runs on Linux operating systems

ESXi

a proprietary hypervisor from VMWare that runs directly on a host machine (bare metal) without the need for a host operating system.

a technology used to split the physical cores of a processor into multiple logical cores. This allows the system to run multiple cores for each operating system in a virtualized environment

Bridged Networking

A VM network connection choice that gives the VM direct access to the hosting computer's network connection but demands that the VM have its own IP address on the local network. This means that every virtual machine can use DHCP to be able to obtain an IP address from your local DHCP server, or you can configure manual IP addressing on each individual virtual machine.

remote hosted virtual desktop (HVD)

A ______________ is a full, thick-client user environment run as a virtual machine (VM) on a server and accessed remotely.

VM escape

An attack in which the attacker runs code on a VM that allows an operating system running within it to break out and interact directly with the hypervisor. Such an exploit could give the attacker access to the host operating system and all other virtual machines (VMs) running on that host. __________________ is the biggest threat to virtualized systems.
