Understanding Virtualization Levels

What is virtualization in computing?

• Virtualization is the same as cloud computing.

• Virtualization is the process of creating virtual versions of physical computing resources.

• Virtualization is the process of increasing physical resource capacity.

• Virtualization refers to the physical enhancement of hardware.

Name the three main types of virtualization.

• Database virtualization

• Application virtualization

• Cloud virtualization

• Hardware virtualization, software virtualization, network virtualization

What is the role of a hypervisor in virtualization?

• The hypervisor is responsible for network security in a data center.

• The role of a hypervisor in virtualization is to manage and allocate hardware resources to multiple virtual machines.

• A hypervisor is used to create backup copies of physical machines.

• A hypervisor is a type of operating system for personal computers.

Differentiate between Type 1 and Type 2 hypervisors.

• Type 1 hypervisors require an operating system to function, while Type 2 hypervisors do not.

• Type 1 hypervisors run on a virtual machine, while Type 2 hypervisors run on hardware.

• Type 1 hypervisors are slower than Type 2 hypervisors due to their architecture.

• Type 1 hypervisors are bare-metal and run directly on hardware, while Type 2 hypervisors are hosted and run on an operating system.

What is hardware virtualization?

• Hardware virtualization is the creation of virtual versions of physical hardware resources, allowing multiple operating systems to run on a single physical machine.

• Hardware virtualization is the duplication of physical hardware for backup purposes.

• Hardware virtualization allows only one operating system to run on multiple machines.

• Hardware virtualization is the process of upgrading physical hardware components.

Explain the concept of OS-level virtualization.

• OS-level virtualization is a technique for running multiple operating systems on a single machine.

• OS-level virtualization is a method that allows multiple containers to run on a single OS kernel, providing isolation and efficient resource management.

• OS-level virtualization is primarily used for running virtual machines instead of containers.

• OS-level virtualization requires separate kernels for each container.

What are the benefits of using virtualization?

• Decreased system performance

• Limited software compatibility

• Increased hardware requirements

• Benefits of using virtualization include resource optimization, cost savings, improved scalability, enhanced security through isolation, and simplified management.

How does virtualization impact resource management?

• Virtualization has no effect on resource utilization or management.

• Virtualization complicates resource management with static allocation.

• Virtualization enhances resource management by optimizing utilization, enabling dynamic allocation, and simplifying management.

• Virtualization decreases resource efficiency by limiting allocation.

What is the purpose of virtual machines?

• To enhance the graphics performance of a system

• To run only one operating system at a time

• The purpose of virtual machines is to run multiple operating systems on a single physical machine, providing isolation and resource management.

• To increase the physical size of a computer

Describe the implementation levels of virtualization.

• Network, database, and user levels

• Firmware, middleware, and service levels

• Cloud, container, and desktop levels

• The implementation levels of virtualization are hardware, operating system, and application levels.
