Understanding Virtualisation Concepts

What is virtualisation primarily used for?

• Increasing physical hardware

• Saving space, cutting costs, and improving functionality and security

• Reducing software capabilities

• Enhancing physical hardware size

What is a virtual machine (VM)?

• A physical device that replaces a computer

• A software that opens an operating system on a single device

• A hardware component that enhances memory

• A network protocol for data transfer

How does a virtual machine operate in relation to the host?

• It is dependent on the host's hardware

• It operates independently of the host

• It requires constant updates from the host

• It cannot function without the host's operating system

What is essential for virtual machines to work smoothly?

• High level of virtual memory

• Increased physical storage

• Faster internet connection

• More physical processors

What are segments or pages in the context of virtual memory?

• Large hardware components

• Small additions to a machine's hardware

• Software applications

• Network protocols

What is the role of virtual memory in a host computer?

• To decrease application performance

• To store and receive data efficiently

• To replace physical memory

• To slow down the operating system

What is Virtual Desktop Infrastructure (VDI)?

• A physical desktop replacement

• A third-party hosted virtual desktop

• A type of virtual machine

• A hardware component for desktops

What is one benefit of using virtual machines?

• They require more physical space

• They are affected by host hardware issues

• They operate independently of the host

• They are slower than physical machines

Which of the following is NOT a benefit of virtualisation?

• Increased physical hardware

• Improved security

• Cost reduction

• Space saving

What happens if something goes wrong with the hardware used to access a VM?

• The VM stops working

• The VM remains unaffected

• The VM requires a reboot

• The VM loses data
