Explanation: Private clouds are used to provide services and applications to a specific organization and may be set up within the private network of the organization or managed by an outside organization.

Explanation: 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.

Explanation: The cloud-based virtual application stream, or cloud-based applications, can provide on-demand software application delivery to end users. In the case of LMS, when a user needs to use the web-based service, the user will open a client (web browser) to access the system. Minimal application code is then forwarded to the client based on the information the user needs.

Explanation: 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.

Explanation: The two type of hypervisors are Type 1 and Type 2. Type 1 hypervisors are usually used on enterprise servers. Enterprise servers rather than virtualized PCs are more likely to be in a data center.

Explanation: Virtual desktop infrastructure (VDI) can be used to deploy entire desktop environments from a server in a data center to clients. VDIs can be persistent, which provides the user with a customizable image that is saved for future use, or non-persistent, which reverts the image back to its initial state when a user logs out.

Explanation: 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.

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

Explanation: With PaaS (platform as a service), a cloud provider provides access to operating systems, development tools, programming languages, and libraries used to develop, test, and deliver applications.

Explanation: 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.​​

Explanation: Type 2 hypervisors, also know as hosted hypervisors, are installed on top of an existing operating system, such as Mac OS, Windows, or Linux.

Explanation: The service needed is a cloud-based storage solution with automatic synchronization. Dropbox is an example of such a solution. Office 365 provides cloud-based applications. Exchange Online is a cloud-based email client. A virtual desktop infrastructure provides a cloud-based virtual desktop environment.

Explanation: A community cloud is a cloud service created for exclusive use by a specific community. The professional association contains members from all over the world and each of them works within the same organization.

Explanation: 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.

Explanation: Type 1 hypervisors are installed directly on a server and are known as “bare metal” solutions giving direct access to hardware resources. They also require a management console and are best suited for enterprise environments.​

Explanation: 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.

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

Explanation: 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.

Explanation: Software-defined networking automatically and rapidly re-configures networking topologies to achieve flexible and responsive networks. Hybrid cloud computing consists of two cloud types connected through a single architecture. Infrastructure provides organizations access to network equipment, virtualized network services, storage, software, and supporting network infrastructure. A hosted hypervisor is operating system-based software used on a host computer to create and manage virtual machines.

Explanation: 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.

Explanation: 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.

Explanation: If a hard drive makes repeated clicking or tapping sounds when the computer is idle, the hard drive is failing. Make a backup and replace the drive as soon as possible. Invalid boot disk errors and files that suddenly will not open are symptoms of hard drive issues.

Explanation: If a hard drive makes repeated clicking or tapping sounds when the computer is idle, the hard drive is failing. Make a backup and replace the drive as soon as possible. Invalid boot disk errors and files that suddenly will not open are symptoms of hard drive issues.

Explanation: If a hard drive makes repeated clicking or tapping sounds when the computer is idle, the hard drive is failing. Make a backup and replace the drive as soon as possible. Invalid boot disk errors and files that suddenly will not open are symptoms of hard drive issues.

Explanation: 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.

Explanation: Type 2 hypervisors are hosted on an underlaying operating system and are best suited for consumer applications and those experimenting with virtualization. Unlike Type 1 hypervisors, Type 2 hypervisors do not require a management console and do not have direct access to hardware.​

Explanation: If a hard drive makes repeated clicking or tapping sounds when the computer is idle, the hard drive is failing. Make a backup and replace the drive as soon as possible. Invalid boot disk errors and files that suddenly will not open are symptoms of hard drive issues.

Explanation: Client-side virtualization enables a host OS to provide a virtual environment within which a guest OS can be installed and be operational as an actual OS. The dual boot configuration will provide an option to run either OS (but not both at the same time). Just using two disks is not a sufficient solution to run two separate OS.

Explanation: 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.
