What special operating system setup is required when running Windows 10 as a virtual machine?

Correct! Wrong!

Correct answer: There is no need for any specific configuration

When running Windows 10 on a virtual computer, no special configuration is required. Hypervisors provide virtual resources (CPU, Memory, etc.) that appear to be real hardware, allowing operating systems to be installed and operate in the same way that they would on physical hosts.

What is the name of the native hypervisor available in Windows 10 Pro and higher?

Correct! Wrong!

Correct answer: Hyper-V

Hyper-V is a native hypervisor that is included with various versions of Windows 10 and Windows Server. It's worth noting that Hyper-V isn't supported in Windows 10 Home. LXD is a hypervisor that operates on Linux operating systems, whereas ESXi is a VMWare proprietary hypervisor that runs directly on a host computer (bare metal) without the requirement for a host operating system.

Which of the following is NOT an advantage of utilizing cloud infrastructure?

Correct! Wrong!

Correct answer: The Cloud Provider will handle security on your behalf

The Cloud infrastructure, like any infrastructure, nevertheless requires extra precautions to maintain its security. The pay-as-you-go model (typically per second or per minute billing), the ability to create and delete servers on demand or automatically, and the ease of provisioning complex services such as database clusters without highly specialized experts are just a few of the advantages of cloud infrastructure.

Which of the following options supports Hardware-Assisted Virtualization (HAV)?

Correct! Wrong!

Correct answer: VT-x

Intel's VT-x technology enables Hardware Assisted Virtualization (HAV). HAV allows virtual hosts to utilise CPUs in an isolated manner.

What component contributes to the separation of network traffic across virtual machines on the same physical host?

Correct! Wrong!

Correct answer: Virtual NIC

Each virtual host will have one or more Virtual Network Interface Cards (VNICs) (NIC). These Virtual NICs are used to redirect network traffic to each virtual host instead of delivering it to all hosts on a server. This is significant because cloud providers frequently host several customers' virtual servers on the same physical server (Resource Pooling).

Which of the following is a synonym for the word "Hypervisor"?

Correct! Wrong!

Correct answer: Virtual Machine Monitor (VMM)

A Hypervisor can be known as a Virtual Machine Monitor or Virtual Machine Manager.

Which of the following is NOT a benefit for Cloud Computing for business?

Correct! Wrong!

Correct answer: Virtually infinite scalability of infrastructure

Scalable infrastructure is a technical benefit of cloud computing, not an economic benefit. Of course, this is still indirectly helpful to a business, but most non-IT department workers at a company will be unfamiliar with the term "scalable infrastructure." It is critical to be able to communicate the commercial and technical benefits of various computing alternatives to your target audience.

The following characteristics are shared by virtualization and cloud computing:

Correct! Wrong!

Correct answer: All of the above

Resources must be highly configurable and adaptable in order to support these features.

Choose the option that best illustrates key attributes cloud computing from the list below.

Correct! Wrong!

Correct answer: Scalable, Shared, Metered Usage, Service, Virtualization

Virtualization is a key enabler of the first four of cloud computing's five key attributes.

Gmail is a web-based email service that is supplied by:

Correct! Wrong!

Correct answer: Google

Which of the following describes a cloud computing delivery model in which clients rent computer resources from vendors that own and maintain all essential equipment and software rather than purchasing hardware and software?

Correct! Wrong!

Correct answer: IaaS

What is the name of Apple's cloud-based email service?

Correct! Wrong!

Correct answer: iCloud Mail

A cloud computing service model that provides remote access to programs in exchange for a monthly or annual membership fee is known as:

Correct! Wrong!

Correct answer: SaaS

In cloud computing, the process of combining computer resources and making them available for shared access by numerous clients is known as:

Correct! Wrong!

Correct answer: Resource pooling

An example of a remote server running a virtualized user OS is

Correct! Wrong!

Correct answer: VDI

Which of the following enables several operating systems to run on the same hardware at the same time?

Correct! Wrong!

Correct answer: Virtualization

Development that happens on a large number of virtual machines and necessitates the use of resources (typically administration related) to keep up with.

Correct! Wrong!

Correct answer: VM Sprawl

Users only pay for the computing capabilities used

Correct! Wrong!

Correct answer: Measured services

A software application that goes on top of an existing operating system and allows numerous virtual operating systems to be hosted on the same system at the same time.

Correct! Wrong!

Correct answer: Type 2 Hypervisor

A cloud service that provides infrastructure as well as software development tools such as run time environments.

Correct! Wrong!

Correct answer: PaaS (Platform as a Service)
