Understanding Virtualisation Concepts

What is the primary purpose of virtualisation in computing?

• To increase the physical size of servers

• To create multiple simulated environments from a single physical hardware system

• To reduce the speed of processing

• To eliminate the need for software updates

Which of the following is NOT a type of virtualisation?

• Network Virtualisation

• Storage Virtualisation

• Application Virtualisation

• Hardware Virtualisation

What is a key benefit of virtualisation?

• Increased hardware costs

• Improved energy efficiency

• Reduced software compatibility

• Decreased system flexibility

How do virtual machines differ from containers?

• Virtual machines are faster to start than containers

• Containers include the entire operating system, while virtual machines do not

• Virtual machines are more lightweight than containers

• Containers share the host OS kernel, while virtual machines have their own OS

What is a hypervisor?

• A type of virtual machine

• A software layer that allows multiple operating systems to share a single hardware host

• A physical server used for virtualisation

• A network protocol for virtualisation

Which of the following is a popular cloud virtualisation technology?

• Microsoft Word

• Amazon Web Services (AWS)

• Adobe Photoshop

• Google Chrome

What is a common security challenge associated with virtualisation?

• Increased physical space requirements

• Hypervisor vulnerabilities

• Reduced data storage capacity

• Slower network speeds

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

• Network Virtualisation

• Desktop Virtualisation

• Server Virtualisation

• Application Virtualisation

What is one advantage of using containers over virtual machines?

• Containers require more resources

• Containers are more secure

• Containers are more lightweight and faster to deploy

• Containers are less flexible

Which of the following is a benefit of using virtualisation in data centres?

• Increased physical server count

• Reduced energy consumption

• Decreased server utilisation

• Increased hardware maintenance
