ISTC2150 - Virtualization, Storage, and Cloud Technologies Chapter 1 Study Guide

What component of virtualization controls all physical memory, and thus has the ability

to make any unused memory pages in each guest available for other virtual machines or

the host computer?

The hypervisor

What virtualization technology makes it possible to avoid overhead associated with

software-managed shadow page tables?

Second Level Address Translation (SLAT)

Which of the following does an operating system installed in a guest virtual machine do?

interacts with hardware through the hypervisor

What hypervisor uses a special guest called Domain 0 that loads along with the

hypervisor and is used to directly access the hardware?

Xen

An ISO image file uses what format to store a disc's contents in a single file on a

computer?

ISO 9660

What type of cloud computing service provides hardware infrastructure along with

necessary operating system software for running client applications?

Platform as a Service

What is the most commonly used form of a Storage Area Network

An iSCSI network

What feature, supported by VMWare, allows the live migration of a running VM from one

host to another?

vMotion

You are working in a VMware vSphere based environment, and have been asked to

create a parent virtual machine that can be shared amongst many users. One of the

requirements of this desired setup is that individual user changes must be kept separate.

What is the best implementation based on the requirements given?

The parent virtual machine should be configured to make use of linked clones.

What is the purpose of the NX/XD CPU feature present in most modern Intel and AMD

processors?

The feature adds a layer of security by marking areas of memory as non-executable.

What is the purpose of a shadow page table when a hypervisor is used?

It tracks the memory pages allocated by each guest VM.

Your work environment consists of a large number of Mac OS X based devices. The

developers in your network have requested virtualization software be installed for their

use. What product should you use?

VMware Fusion

What is the oldest version of Windows Server to support the use of Microsoft's Hyper-V?

Windows Server 2008

Why are type-1 hypervisors more efficient than type-2 hypervisors?

A type-1 hypervisor accesses the physical hardware directly.

When a Xen based guest VM makes a request for a hardware resource, such as reading

from a disk, where is the request sent to?

It is sent to the Domain 0 guest.

What statement regarding the use of Hyper-V is accurate?

Hyper-V requires a 64-bit processor with hardware virtualization support.

When using the VMware Horizon software, where do client desktop operating systems

run?

They run on a VMware vSphere ESXi host.

The VDI disk file format is native to what virtualization platform?

Oracle VirtualBox

What statement regarding virtual disk types is accurate?

A dynamic disk does not immediately allocate the configured size of the disk.

You have been tasked with creating a virtual machine that will require access to the

Internet, but should be prevented from sending and receiving packets directly from the

physical network. What network mode should be used?

shared (NAT) mode

You have been tasked with creating a virtual machine that will be providing hosted

services on the physical network, and possibly the Internet. What network mode should

be used?

bridged mode

What format enables a virtual machine to be moved between virtualization platforms,

and is often used for deploying virtual appliances?

Open Virtualization Format (OVF)

What is NOT a product designed specifically for the virtualization of applications within a

VDI environment?

VMware Fusion

You are employed by a cloud service provider that offers virtual machine services along

with virtual switches, storage, firewalls, and other virtual devices. What type of cloud

environment does your employer sell?

Infrastructure as a Service

What open standard was developed as a result of collaboration between NASA and

Rackspace?

OpenStack
