CompTIA Virtualization and Cloud Computing Test #1
What special operating system setup is required when running Windows 10 as a virtual machine?
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 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 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 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 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 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 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 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 answer: Scalable, Shared, Metered Usage, Service, Virtualization
Virtualization is a key enabler of the first four of cloud computing's five key attributes.
