A physical computer A networking protocol The creation of a virtual (rather than actual) version of something, such as an operating system or a storage device A cloud computing hosting service 2/12 What is a hypervisor? A software that enables virtualization by creating and managing virtual machines A hardware component that provides high-speed memory access A network configuration tool A file system used in virtualized environments 3/12 Which of the following is NOT a type of virtualization? Physicalization Server virtualization Application virtualization Network virtualization 4/12 What are the benefits of virtualization? Increase in physical hardware efficiency Improved disaster recovery and backup capabilities Decreased scalability and flexibility Higher energy consumption 5/12 What is live migration in virtualization? The process of moving a running virtual machine between physical servers without interruption The creation of multiple virtual devices from a physical device The virtualization of network infrastructure The ability to allocate hardware resources dynamically 6/12 Which of the following is an open-source hypervisor? KVM Xen VMware ESXi Hyper-V 7/12 What is para-virtualization? A technique that allows the guest operating system to be aware of the hypervisor and optimize its own operations A method of running multiple isolated operating systems on a single physical host computer The process of creating virtual machines on a hosted hypervisor The replication of virtual machines for high availability 8/12 What is the purpose of a snapshot in virtualization? To remove unused files and optimize storage space To capture the state, data, and configuration of a virtual machine at a specific point in time To manage virtual network connections To provide access to virtualized storage resources 9/12 What is the main difference between Type 1 and Type 2 hypervisors? Type 1 hypervisors run directly on the host's hardware, while Type 2 hypervisors run as software on top of an existing operating system Type 2 hypervisors have better performance than Type 1 hypervisors Type 1 hypervisors are only used for server virtualization, while Type 2 hypervisors are used for desktop virtualization Type 2 hypervisors require additional virtualization software 10/12 Which of the following is a popular containerization technology? Xen KVM Docker Hyper-V 11/12 What is the purpose of virtual machine snapshots? To capture the state of a VM at a specific point in time and enable restoration to that state if needed To migrate a VM from one physical server to another To allocate hardware resources to a VM To virtualize storage for a VM 12/12 What is the purpose of a virtual switch? To provide access to external networks for virtual machines To manage storage resources for virtual machines To enable communication between virtual machines on the same host To configure virtual machine settings
