Which of the following BEST describes a community cloud implementation?

Designed to be shared by several organizations.

Rachel, an employee in the support department, wants to run a virtual machine on her computer to troubleshoot customer issues. Which of the following must she complete before virtualization will work on her computer?

Enable virtualization support in the BIOS settings.

Your company currently has an on-premises cloud solution that provides services to its employees. However, the company would like to begin offering some services to the public from the cloud. Which of the following cloud computing solutions would BEST meet your company's new cloud computing requirements?

Hybrid Cloud The best solution would be to implement a hybrid cloud model, which would accommodate the private on-premises cloud solution and also allow public access to company services.

What does the term cloud mean when referring to cloud computing?

It is a metaphor for the internet based on the basic cloud drawing used to represent a telephone network.

What are the benefits of installing integration services (IS) on a Hyper-V Windows virtual machine? (Select two.)

Lets you cut and paste between the virtual machine and host. Dramatically improves performance by installing Hyper-V aware drivers.

Which of the following BEST describes the Platform as a Service (PaaS) cloud computing service model?

PaaS delivers everything a developer needs to build an application on the existing cloud infrastructure.

Match each virtualization component on the left with the appropriate description on the right. Each type of component may be used once, more than once, or not at all.

Provides the hardware necessary to create a virtualized environment. (Host machine) A thin layer of software that resides between the virtual machine and hardware. (Hypervisor) A software implementation of a computer. (Virtual Machine) A file created to store data. (Virtual hard disk) Allows virtual machines to interact with hardware. (Hypervisor)

While creating a virtual machine, you decide to set it up to use an external network. What else do you need to do to enable the external network configuration?

Select a NIC using the virtual switch manager.

Which of the following BEST describes the overall purpose of virtualization?

The ability to install and run multiple operating systems on a single physical machine

You want to create a virtualization environment that runs directly on the host machine's hardware to manage the virtual machines. Which of the following virtualization types should you use?

Type 1 hypervisor A hypervisor is a virtualization component that allows virtual machines to interact with hardware on the host machine. Type 1 runs directly on the host machine's hardware to manage the guest VMs.

As the network engineer for a large financial institution, you have been given the responsibility to provide a new financial desktop to the financial advisors in all company branch offices. The requirements for the software desktop include: It must be a virtualization solution. It must be hosted in the cloud by a third party. It must run on a tablet. Which of the following virtualization types BEST meets your desktop software requirements?

VDI

Which term refers to a software implementation of a computer system that executes programs like a physical machine?

Virtual machine

Which term describes the layer of software that resides between the virtual operating system and the physical hardware in a virtualization environment?

Hypervisor

Match each cloud computing definition on the left with the appropriate characteristic on the right. Each characteristic may be used once, more than once, or not at all.

Provides resources to a single organization. (Private cloud) Combines public, private, and community cloud resources from different service providers. (Hybrid Cloud) Designed to be shared by several organizations. (Community cloud) Provides computing resources that are accessible to the general public. (Public cloud) Keeps an organization's data separate and secure from any other organization using the same service provider. (Private Cloud)

A company has subscribed to a cloud service that offers cloud applications and storage space. Through acquisition, the number of company employees quickly doubled. The cloud service vendor was able to add cloud services for these additional employees without requiring hardware changes. Which of the following cloud concepts does this represent?

Rapid elasticity

Which of the following cloud computing solutions delivers software applications to a client either over the internet or on a local area network?

SaaS Software as a Service (SaaS) delivers software applications to a client either over the internet or on a local area network.

Your company cloud service currently provides data storage, processing, and network connectivity that hosts several services and applications used by your employees. You want to transition to a cloud service that provides many of these services and applications natively without the IT department needing to constantly maintain and update the services and applications. In addition, the IT department wants to make sure that the cloud service provides employees with resources that are segregated from other employees. Which of the following cloud service solutions meets these requirements?

SaaS with a simple multi-tenancy implementation.

You want to create a virtual machine environment in which you can develop and test new software. Which virtualization benefit BEST describes the testing environment that you want to implement?

Sandbox Because a virtual machine is easy to delete or create, you can run tests without permanent impact, giving you a playground (or sandbox) to create and test new software.

You have been tasked with creating a new software application and test the development of the software. You want an environment that can be isolated from the production network for the development and testing. What virtualization feature will BEST meet your application development requirements?

Sandbox virtualization Sandbox virtualization is the process of creating an isolated testing environment. Virtualization lets you easily create a sandbox by isolating components from the production network. Using a virtualized sandbox (sometimes known as a playground) gives you a safe place to create new software, test software development, install new software, or upgrade existing software without risking the production network

Which of the following factors significantly determine the number of virtual machines that a host can accommodate? (Select two.)

The components installed on host machine. What has been allocated by the Hyper-V manager.
