Question

What 6 actions should be taken to use Client Hyper-V? Describe the steps of each.

Answer 1

**Action** **Description** Enable Hyper-V To enable Hyper-V, complete the following steps: 1. Open **Settings**. 2. Select **Apps**. 3. Under Related settings, select **Programs and Features**. 4. In the left pane, select **Turn Windows features on or off**. 5. Mark **Hyper-V** and select **OK**. The system will reboot several times as Hyper-V is enabled. Configure Virtual Networking To configure virtual networking: * Choose the type of network you want to set up: * External virtual network * Internal virtual network * Private virtual network * Use the Virtual Switch Manager to select an NIC if you are configuring an external virtual network. Create Virtual Machines To create virtual machines, run Hyper-V Manager and specify the following parameters: * A name for the new VM * The virtual machine's generation * The amount of RAM the VM is allowed to use * The shared network switch that you created earlier for the VM to use for networking * The VHD file you want to use. * You can create a new VHD file or use an existing one. * You can use the .vhdx or .vhd format. The .vhd format is older, but is more compatible with other hypervisors. * The optical drive you want to use. * You can use either a physical optical drive or a virtual .iso file as the optical drive used by the VM. * You can install an operating system directly from an ISO file instead of burning it to disk. Start the Virtual Machine To start the virtual machine, power it on in Hyper-V Manager. If you created a new VHD file, then you must install an operating system. If you choose to install Windows, then you should install Integration Services (IS) after the installation is complete. IS dramatically improves VM performance by installing modified disk, network, and mouse drivers inside the VM that are Hyper-V aware. In addition, IS lets you cut and paste between the host and guest Windows operating systems installed within VMs. It also enables the mouse to move smoothly in and out of the Virtual Machine Connection window. Connect to the Virtual Machine You use the Virtual Machine Connection window to interact with a VM. To connect to a VM, run Hyper-V Manager, select the VM that you want to access, and connect to it. You can start, stop, pause, and take snapshots (also called *checkpoints*) of the virtual machine's current configuration using the Hyper-V manager window. Move a Virtual Machine Server versions of Hyper-V provide many virtual machine migration tools that you can use to move a VM between hypervisor hosts. However, Client Hyper-V does not include most of these features. To move a virtual machine between client Hyper-V hosts, you must do the following: 1. Export the VM on the source system using Hyper-V Manager. 2. Copy the exported VM files from the source system to the destination system. 3. Import the VM on the destination system using Hyper-V Manager. As you do so, you must select one of the following import options: * Register the VM in place using its existing unique ID. * Restore the VM using its existing unique ID. * Copy the VM and create a new unique ID.

Answer 2

*Cloud computing* is a combination of software, data access, computation, and storage services provided to clients through the internet. * The term *cloud* is a metaphor for the internet, based on the basic cloud drawing used to represent the telephone network. It is now used to describe the internet infrastructure in computer network diagrams. * Typical cloud computing providers deliver common business applications that are accessed from a web service or software (like a web browser). * The cloud connection can exist over the internet or a LAN. Cloud computing does not require end-user knowledge of the physical location and configuration of the system that delivers the services

Answer 3

**Type** **Description** Public cloud A public cloud can be accessed by anyone. Cloud-based computing resources such as platforms, applications, and storage are made available to the general public by a cloud service provider. The service provider may or may not require a fee for using these resources. For example, Google provides many publicly accessible cloud applications, such as Gmail and Google Docs. Private cloud A private cloud provides resources to a single organization. Access is granted to only the users within the organization. Private clouds can be hosted internally, but because of the expense and expertise required to do so, they are typically hosted externally by a third party. An organization commonly enters into an agreement with a cloud service provider, which provides secure access to cloud-based resources. The organization's data is kept separate and secure from any other organization using the same service provider. Community cloud A community cloud is designed to be shared by several organizations. Access is granted only to the users within the organizations who are sharing the community cloud infrastructure. Community clouds can be hosted internally, with each organization sharing the cost of implementation and maintenance. Because of the expense and expertise required to do so, community clouds are commonly hosted externally by a third party. Hybrid cloud A *hybrid cloud* is a combination of public, private, and community cloud resources from different service providers. The goal behind a hybrid cloud is to expand the functionality of a given cloud service by integrating it with other cloud services.

Answer 4

The advantages of cloud computing are: * Flexibility of access * Rapid elasticity or scalable provisioning. Rapid elasticity is the ability to provide scalable services. In other words, rapid elasticity allows users to automatically request additional space in the cloud or other types of services. * Measured service. Measured service are services where the cloud provider measures or monitors the provision of services for various reasons, including billing, effective use of resources, or overall predictive planning. * Resource pooling. Resource pooling allows providers to serve multiple clients and customers with provisional and scalable services. These services can be adjusted to each client's needs without any changes being apparent to the client or end user. Through modern scalable systems involved in cloud computing and software as a service (SaaS), providers can create a sense of infinite or immediately available resources by controlling resource adjustments at a meta level. This allows customers to change their levels of service without being subject to any of the limitations of physical or virtual resources. * On-demand computing (ODC). ODC or metering of services is defined as "pay and use" computing power. ODC allows resources to be provided on an as-needed and when-needed basis. * Ease of use * API availability * Ability to "try out" software applications in some cloud computing service models

Answer 5

**Model** **Description** Infrastructure as a Service (IaaS) IaaS delivers infrastructure to the client, such as processing, storage, networks, and virtualized environments. The client deploys and runs software without purchasing servers, data center space, or network equipment. Platform as a Service (PaaS) PaaS delivers everything a developer needs to build an application. The deployment comes without the cost and complexity of buying and managing the underlying hardware and software layers. Software as a Service (SaaS) SaaS delivers software applications to the client either over the internet or on a local area network. SaaS can be: * A simple multi-tenancy implementation in which customers have their own resources that are segregated from other customers. * A fine grain multi-tenancy implementation in which resources are shared, but data is segregated from other customers.

Answer 6

Cloud computing service providers reduce the risk of security breaches in multiple ways. They: * Authenticate all users who access the service and allow users to access only the applications and data that they need. * Segregate each organization's centrally stored data. * Verify, test, and apply updates to the infrastructure. * Establish a formal process for all facets of the service, from user requests to major data breaches and catastrophic events. * Implement security monitoring of things like usage and unusual behavior. * Implement encryption up to the point of use, such as the client's web browser. * Probe for security holes with a third-party service provider. * Comply with all regulatory measures, like the Sarbanes-Oxley Act.
