Unit 1a

Question 1

A __ is a combination of software applications and an operating system that is tricked into thinking it has its own dedicated hardware

Answer 1

Virtual Machine

Question 2

__ separates hardware and software. This offers us a much better utilization rate of server hardware while still isolating applications.

Answer 2

Virtualization

Question 3

The computer on which the virtualized environment resides is called the __

Answer 3

Host Server

Question 4

This is the link managing the communications between the host server and the virtualized environment. It dynamically assigns resources such as memory, disk space, and physical devices.

Answer 4

Hypervisor, or Virtual Machine Monitor

Question 5

This is installed on a virtual computer architecture and allows for end-user interaction that is indistinguishable from a standard physical computer

Answer 5

Guest OS

Question 6

A virtualization technology used to separate a desktop computer environment from the physical device used to access it.

Answer 6

Client Virtualization

Question 7

The partition of a physical server into smaller virtual servers

Answer 7

Server Virtualization

Question 8

__ is running specific software applications on central servers while separating these applications from the underlying hardware the end users are accessing. This allows multiple users to simultaneously access the same application installed on a central server.

Answer 8

Application Virtualization

Question 9

The pooling of physical storage from multiple network storage devices into what appears to be a single storage device managed from a central console. This is commonly used in Storage Area Networks (SANs)

Answer 9

Storage Virtualization

Question 10

A copy of a virtual machine at a given point in time

Answer 10

Snapshot

Question 11

This term refers to reducing the cost of maintaining the number of servers the organization may have had, and is the most obvious application of virtualization.

Answer 11

Server Consolidation

Question 12

This involves running two or more VMs on separate pieces of hardware and dividing the regular workload between them. It also protects against single point of failure issues.

Answer 12

Load Balancing

Question 13

Utilizes virtualization software to manage a group or pool of virtualized servers

Answer 13

Server Pooling

Question 14

This term refers to products and processes helping IT organizations respond to catastrophic situations

Answer 14

Disaster Recovery

Question 15

This type of virtualization involves virtualized servers where virtualization software is installed directly on the machine hardware rather than on an operating system. Comes with features for resource management, high availability, and security

Answer 15

Bare-Metal Virtualization

Question 16

This type of virtualization utilizes a hypervisor and requires an operating system. It has higher memory and processor usage and can degrade virtual machine performance.

Answer 16

Hosted Virtualization

Question 17

The consolidation of servers through the use of VMs reduces the number of physical servers required to meet operational needs. This reduces server problems, increases physical server utilization, and improves infrastructure manageability

Answer 17

Infrastructure Simplification

Question 18

The fewer servers you need to deliver and meet business needs reduces this. It produces an increase in the return on investment when using virtualization.

Answer 18

Total Cost of Ownership
