2.3.3 Cloud and Virtualization Quiz Answers 1

  • teleworkers
  • wireless
  • tall servers
  • virtualization

Explanation: Cloud computing involves computers, software, servers, network devices, and other services physically held at a remote location. Virtualization is used by the cloud computing vendors so they can provide multiple servers, networks, applications, operating systems, etc. to clients without having to buy the equipment for each one. Virtualization of servers, for example, allows multiple servers to be on one physical server. Each server could be for a different client if necessary.

2. Which three features represent benefits of virtualization? (Choose three.)

  • less power consumption
  • less employee technical training
  • less device monitoring
  • less equipment
  • improved disaster recovery
  • fewer security requirements

Explanation: Virtualization is the ability to run many instances of an OS simultaneously on the same hardware platform. This reduces the amount of equipment that is required, thus resulting in less power consumption and improved disaster recovery

3. Which term describes the type of cloud computing service that provides applications over the web?

  • IaaS
  • ITaaS
  • PaaS
  • SaaS

Explanation: Software as a service (SaaS) delivers applications over the web to end users. Infrastructure as a service (IaaS) provides hardware and software for companies. Platform as a service (PaaS) supplies tools and services used to deliver applications to end users. IT as a service (ITaaS) supplies the talents of IT professionals to companies in order to support applications, platforms, and infrastructure devices.

4. Saving your photos to a storage location maintained by your service provider is an example of ________.

9. Which piece of software is responsible for creating virtual machines and providing them access to resources on a physical machine?

  • hypervisor
  • supervisor
  • host operating system
  • hosted operating system

Explanation: The hypervisor creates and manages virtual machines. A hypervisor is able to run multiple virtual machines on a single host computer. The hypervisor allocates the physical system resources, such as a CPU, RAM, and hard drive, to each virtual machine as needed. This ensures that the operation of one virtual machine does not interfere with another.
