ITE 8 Chapter 9 Exam Answers | ITE 7 Chapter 9 Exam Answers Full 100% 2023 2024

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

   • server hardware needs
   • physical footprint
   • power and air conditioning
   • operating system license requirements
   • virus and spyware attacks
     

     Answers Explanation & Hints: Traditionally, one server was built within one machine with one operating system. This server required power, a cool environment, and a method of backup. Virtualized servers require more robust hardware than a standard machine because a computer or server that is in a virtual machine commonly shares hardware with one or more servers and operating systems. By placing multiple servers within the same physical case, space is saved. Virtualized systems still need the proper licenses for operating systems or applications or both and still need the proper security applications and settings applied.

2. Match the definition to the type of cloud.

   

   Answers Explanation & Hints: Public cloud services are made available to the general population. Private cloud services are intended for a specific organization or entity. A custom cloud is built to meet the needs of a specific industry. A hybrid cloud is made up of two or more clouds that are connected via a single architecture.

3. 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.
     

     Answers Explanation & Hints: Benefits of virtualization include cost savings, the use of multiple operating systems on a single PC, and isolation for software testing.

4. A small company is considering moving many of its data center functions to the cloud. What are 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.
   • Cloud services enable the company to own and administer its own servers and storage devices.
   • The company can increase processing and storage capacity as needed and then decrease capacity when it is no longer needed.
   • Single-tenant data centers can easily grow to accommodate increasing data storage requirements.
   • The company does not need to be concerned about how to handle increasing data storage and processing demands with in-house data center equipment.
     

     Answers Explanation & Hints: Cloud computing offers many advantages to the company. Since the cloud data storage and processing facilities are owned by third-parties, the company does not need to be concerned about how it will handle increasing data storage and processing demands with its own data center equipment. The company can easily increase or decrease processing power and storage capacity based on need. Also, cloud services are billed by usage, so the company does not have the costs of supporting its own expensive data center that is not always used to maximum capacity.

5. 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 lab exercises are performed faster inside of 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 viruses and worms will have limited functionality inside the virtualized environment.
     

     Answers Explanation & Hints: Virtualization can create a controlled environment that is isolated from external networks. Because of shared system resources, the performance inside a virtual environment will not be faster. However, the benefit is that a virtual environment provides a safe platform for information security analysis.

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

   • data analytics
   • Cloud computing
   • virtualization
   • micromarketing
     

     Answers Explanation & Hints: Cloud computing allows organizations to eliminate the need for on-site IT equipment, maintenance, and management. Cloud computing allows organizations to expand their services or capabilities while avoiding the increased costs of energy and space.

7. True or False.

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

   • true
   • false
     

     Answers Explanation & Hints: False. Although the terms cloud computing and virtualization are often used interchangeably, they actually mean two different things. Virtualization is a component within cloud computing that separates the operating systems from the underlying hardware, whereas cloud computing separates the application from the hardware.

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

   • guarantee of power
   • support of live migration
   • supply of consistent air flow
   • improvement of business practices
     

     Answers Explanation & Hints: Live migration allows moving of one virtual server to another virtual server that could be in a different location that is some distance from the original data center.

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

   • Type 1
   • Type 2
   • Nexus
   • Hadoop

    • It is a device that filters and checks security credentials.
    • It is used to create and manage multiple VM instances on a host machine.
    • It is used by ISPs to monitor cloud computing resources.
    • It is software used to coordinate and prepare data for analysis.
    • It is a device that synchronizes a group of sensors.
      

      Answers Explanation & Hints: A hypervisor is a key component of virtualization. A hypervisor is often software-based and is used to create and manage multiple VM instances.

11. Which statement describes a characteristic of cloud computing?

    • A business can connect directly to the Internet without the use of an ISP.
    • Applications can be accessed over the Internet by individual users or businesses using any device, anywhere in the world.
    • Devices can connect to the Internet through existing electrical wiring.
    • Investment in new infrastructure is required in order to access the cloud.
      

      Answers Explanation & Hints: Cloud computing allows users to access applications, back up and store files, and perform tasks without needing additional software or servers. Cloud users access resources through subscription-based or pay-per-use services, in real time, using nothing more than a web browser.

12. A technician needs to use an application that is not supported by Windows operating systems on the PC. How can the technician make this application run on the PC?

    • Use the Windows Compatibility mode.
    • Install the application with elevated permissions as administrator.
    • Create a virtual machine with an operating system that supports the application.
    • Install the application in safe mode.
      

      Answers Explanation & Hints: Windows Compatibility mode will only allow an application to run as long as it is supported by the Windows operating system. The application cannot be installed if the operating system does not support it. It is necessary in this case to create a virtual machine with an operating system, as the guest OS, that supports the application.

13. Which Cloud computing service would be best for an organization that does not have the technical knowledge to host and maintain applications at their local site?

    • SaaS
    • IaaS
    • PaaS
    • ITaaS
      

      Answers Explanation & Hints: Software as a Service (SaaS) allows a business to host an application through a Cloud provider. The Cloud provider manages access to the application and maintains the application. The application can be utilized by any authorized device with an Internet connection.

14. What is a difference between the functions of Cloud computing and virtualization?

    • Cloud computing utilizes data center technology whereas virtualization is not used in data centers.
    • Cloud computing requires hypervisor technology whereas virtualization is a fault tolerance technology.
    • Cloud computing separates the application from the hardware whereas virtualization separates the OS from the underlying hardware.
    • Cloud computing provides services on web-based access whereas virtualization provides services on data access through virtualized Internet connections.
      

      Answers Explanation & Hints: Cloud computing separates the application from the hardware. Virtualization separates the OS from the underlying hardware. Virtualization is a typical component within cloud computing. Virtualization is also widely used in data centers. Although the implementation of virtualization facilitates an easy server fault tolerance setup, it is not a fault tolerance technology by design. The Internet connection from a data center or service provider needs redundant physical WAN connections to ISPs.​​
