MCQ QUESTIONS ON VIRTUALIZATION

What is the main purpose of server virtualization?

• Decreasing system performance

• Optimizing resources and increasing efficiency

• Reducing security measures

• Increasing hardware costs

Which type of virtualization allows multiple operating systems to run on a single physical machine?

• Containerization

• Emulation

• Partitioning

• Hypervisor

What is the primary benefit of application virtualization?

• Improved user experience with virtualized applications

• Enhanced security of the virtualized applications

• Increased hardware utilization

• Isolation of applications from the underlying operating system

What is the difference between full virtualization and para-virtualization?

• Full virtualization requires the guest operating system to be modified, while para-virtualization allows the guest operating system to run without any modification

• Full virtualization and para-virtualization both require the guest operating system to be modified

• Full virtualization allows the guest operating system to run without any modification, while para-virtualization requires the guest operating system to be modified to run on the virtual machine.

• Full virtualization and para-virtualization do not have any difference

What is network virtualization and how does it work?

• Option B: Network virtualization is the process of physically connecting all devices in a network to create a virtual network.

• Option A: Network virtualization is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity.

• Option D: Network virtualization is the process of replacing physical network devices with virtual reality simulations.

• Option C: Network virtualization is the process of encrypting all network traffic to create a secure virtual network.

What are the different types of storage virtualization?

• Database virtualization, application virtualization, and desktop virtualization

• Cloud virtualization, network virtualization, and server virtualization

• Block virtualization, file virtualization, and object virtualization

• Memory virtualization, CPU virtualization, and GPU virtualization

What is the role of hypervisor in virtualization?

• Manages network security

• Installs operating systems

• Manages and runs virtual machines

• Creates physical servers

What are the advantages of desktop virtualization?

• Improved security, centralized management, cost savings, and flexibility.

• No change in security, no management, no cost savings, and no flexibility

• No impact on security, no centralized management, no cost savings, and lack of flexibility

• Decreased security, decentralized management, increased cost, and rigidity

How does hardware virtualization differ from software virtualization?

• Hardware virtualization is only used for personal computers, while software virtualization is used for servers.

• Hardware virtualization uses physical hardware, while software virtualization uses a software layer.

• Hardware virtualization uses a software layer, while software virtualization uses physical hardware.

• Hardware virtualization and software virtualization are the same thing.

What are the security implications of virtualization?

• Reduced cost of hardware

• Improved user experience

• Security implications include new attack surfaces, potential vulnerabilities, and the need for strong isolation between virtual machines.

• Increased performance and efficiency
