Chapter 9 | Exam Review

A software engineer is involved in the development of an application. For usability tests, the engineer needs to make sure that the application will work in both Windows 7 and Windows 8 environments. The features and functions must be verified in the actual OS environment. The engineer is using a Windows 7 workstation. What two technologies can help the engineer achieve the usability tests? (Choose two.)

• Dual boot

• Two separate hard disks

• Two separate CPUs

• Client-side virtualization

• Storage redundancy

Which two business and technical challenges does implementing virtualization within a data center help businesses to overcome? (Choose two.)

• Physical footprint

• Power and air conditioning

• Operating system license requirements

• Virus and spyware attacks

• Server hardware needs

What are two advantages of using PC virtualization? (Choose two.)

• It prevents viruses and worms from functioning in a virtualized environment.

• It allows multiple operating systems to run on a single PC simultaneously.

• It boosts the performance of the host machine through virtualization.

• It can provide cost savings.

• It allows network threat identification.

A small company is considering moving many of its data center functions to the cloud. What are the three advantages of this plan? (Choose three.)

• The company only needs to pay for the amount of processing and storage capacity that it uses.

• Cloud services are billed at a fixed fee no matter how much processing and storage are used by the company.

• The company can increase processing and storage capacity as needed and then decrease capacity when it is no longer needed.

• The company does not need to be concerned about how to handle increasing data storage and processing demands with in-house data center equipment.

• Single-tenant data centers can easily grow to accommodate increasing data storage requirements.

A college uses virtualization technology to deploy information security courses. Some of the lab exercises involve studying the characteristics of computer viruses and worms. What is an advantage of conducting the lab exercises inside the virtualized environment as opposed to using actual PCs?

• The viruses and worms will have limited functionality inside the virtualized environment.

• The virtualization environment has better tools to develop mitigation solutions.

• Virus and worm attacks are more easily controlled in a virtualized environment, thus helping to protect the college network and its devices from attack.​

• The lab exercises are performed faster inside of the virtualized environment.

What technology allows users to access data anywhere and at any time?

• Data analytics

• Micromarketing

• Virtualization

• Cloud computing

True or False.

Cloud computing and virtualization are different terms that refer to the same thing.

• True

• False

How does virtualization help with disaster recovery within a data center?

• Improvement of business practices

• Guarantee of power

• Support of live migration

• Supply of consistent air flow

Which type of hypervisor would most likely be used in a data center?

• Hadoop

• Type 1

• Type 2

• Nexus

What is the main function of a hypervisor?

• It is a device that filters and checks security credentials.

• It is software used to coordinate and prepare data for analysis.

• It is used by ISPs to monitor cloud computing resources.

• It is a device that synchronizes a group of sensors.

• It is used to create and manage multiple VM instances on a host machine.
