Overview of Virtualization ed1

What is the definition of virtualization?

• Abstraction of physical components into logical objects

• A method to increase hardware performance

• A technique for data storage

• A way to enhance security

What are the problems with non-virtualized systems?

• Resource underutilization and high costs

• Increased security risks and limited flexibility

• Complex disaster recovery processes

• All of the above

What are the benefits of virtualization?

• Cost savings and dynamic resource allocation

• Increased hardware dependency

• Limited flexibility

• Higher infrastructure costs

What is a hypervisor?

• A software that manages virtual resources

• A type of physical server

• A network device

• A storage solution

What is the role of a hypervisor in virtualization?

• To manage virtual machines and resources

• To increase physical hardware performance

• To provide network security

• To store data

What is the difference between Type 1 and Type 2 hypervisors?

• Type 1 runs directly on hardware, Type 2 runs on an OS

• Type 1 is more secure than Type 2

• Type 2 is faster than Type 1

• There is no difference

What does the term 'elasticity' refer to in virtualization?

• The ability to scale resources dynamically

• The ability to secure data

• The ability to increase hardware performance

• The ability to create backups

What is the purpose of live migration in virtualization?

• To move VMs between servers without downtime

• To create backups of VMs

• To increase security

• To enhance performance

What is a virtual machine (VM)?

• An isolated duplicate of a physical machine

• A type of physical server

• A network device

• A storage solution

What is the significance of the virtualization layer?

• It replicates environments for guests

• It increases hardware performance

• It provides network security

• It stores data
