CSC1112 Chapter 11 Virtualization

What is the primary goal of virtualization?

• To reduce software complexity

• To improve resource utilization and flexibility

• To enhance user interface design

• To increase hardware costs

What does a hypervisor do in virtualization?

• It creates and manages virtual machines

• It performs data backup and recovery

• It enhances network security

• It develops software applications

Which type of hypervisor runs directly on the physical hardware?

• Type 1 (Bare-Metal) Hypervisor

• Type 2 (Hosted) Hypervisor

• Type 3 (Embedded) Hypervisor

• Type 4 (Cloud-based) Hypervisor

What is an example of a Type 2 hypervisor?

• VMware ESXi

• Microsoft Hyper-V

• Oracle VirtualBox

• Xen

In full virtualization, how does the guest operating system run?

• It is aware of the virtualization

• It runs unmodified as if on actual physical hardware

• It interacts directly with the hypervisor

• It uses special CPU extensions

Which type of virtualization requires modification of the guest OS?

• Full Virtualization

• Para Virtualization

• Hardware-Assisted Virtualization

• Network Virtualization

What is a benefit of hardware-assisted virtualization?

• Increased complexity

• Improved performance and lower overhead

• Complete software emulation

• Higher costs

Which example is a benefit of virtualization?

• Reduced need for physical hardware

• Increased capital expenses

• More complex management

• Slower deployment of resources

What challenge does virtualization introduce?

• Simple system recovery

• Performance overhead

• Easier maintenance

• Lower security risks

Which cloud computing service provides virtual machines, storage, and networks over the internet?

• Software as a Service (SaaS)

• Platform as a Service (PaaS)

• Infrastructure as a Service (IaaS)

• Network as a Service (NaaS)
