Hypervisor Quiz

What is a hypervisor?

• A type of network protocol

• A type of server that can create multiple virtual machines

• A type of computer hardware

• A type of operating system

Answer explanation

A hypervisor is a type of server that can create multiple virtual machines. It allows for efficient utilization of hardware resources and enables the isolation and management of virtualized environments.

What is a virtual machine?

• A type of software

• A simulation of a real computer

• A type of storage device

• A physical computer

Answer explanation

A virtual machine is a simulation of a real computer, allowing users to run multiple operating systems on a single physical machine. It provides an isolated environment for software execution, enhancing flexibility and resource utilization.

What is the role of a hypervisor in creating virtual machines?

• Allocating resources from the virtual machines to the host machine

• Creating a simulation of a real computer

• Keeping the virtual machines connected to each other

• Creating a barrier between the virtual machines and the host machine

Answer explanation

The role of a hypervisor is to create a barrier between the virtual machines and the host machine, ensuring isolation and security.

What is the physical computer that runs the hypervisor called?

• Guest machine

• Simulated machine

• Virtual machine

• Host machine

Answer explanation

The physical computer that runs the hypervisor is called the host machine. It is responsible for managing and running the virtual machines.

What is the purpose of keeping virtual machines independent of each other?

• To prevent them from running different operating systems

• To ensure they can share files and applications

• To allow for easy movement between hypervisors

• To prevent interference and maintain security

Answer explanation

The purpose of keeping virtual machines independent is to prevent interference and maintain security.

What is the benefit of virtual machines being portable?

• They can be easily copied and pasted

• They can only run on specific hardware

• They can be accessed from any internet-connected device

• They can be used to run multiple operating systems simultaneously

Answer explanation

Virtual machines being portable allows them to be easily copied and pasted, providing flexibility and convenience in deployment and management.

What happens if a virus infects a virtual machine?

• It has no effect on the virtual machine

• It can spread to the host machine

• It can be easily removed by deleting the virtual machine

• It can cause the hypervisor to malfunction

Answer explanation

If a virus infects a virtual machine, it can be easily removed by deleting the virtual machine. This ensures that the virus does not spread to the host machine or cause the hypervisor to malfunction.

What is the purpose of the hypervisor in relation to virtual machine security?

• To prevent any interaction between the virtual machines and the host machine

• To allow virtual machines to share resources with each other

• To monitor the activity of the virtual machines

• To ensure that virtual machines can access all files on the host machine

Answer explanation

The purpose of the hypervisor is to prevent interaction between virtual machines and the host machine, ensuring security.

What is the main advantage of using virtual machines for business purposes?

• They are more cost-effective than physical computers

• They can run multiple operating systems

• They have better performance than physical computers

• They are easier to set up and maintain

Answer explanation

The main advantage of using virtual machines for business purposes is that they can run multiple operating systems, allowing for greater flexibility and compatibility.

What is the recommended action if there is an issue with a virtual machine?

• Contact the hypervisor provider for support

• Install antivirus software on the virtual machine

• Delete the virtual machine and create a new one

• Restart the host machine

Answer explanation

If there is an issue with a virtual machine, the recommended action is to delete the virtual machine and create a new one. This ensures a fresh start and resolves any underlying problems.
