Question

Accepted Answer

Full virtualization allows multiple operating systems to run on a single physical machine, with each operating system running as if it were on dedicated hardware. A hypervisor, such as VMware or Hyper-V, manages the virtual machines and allocates resources from the physical machine to each VM. This allows multiple operating systems to coexist without interference, maximizing resource utilization and flexibility.    Option A Para-virtualization is incorrect because para-virtualization requires modified guest operating systems, whereas full virtualization does not.   Option C Containerization is incorrect because containers share the host operating system kernel, making them lighter but less isolated compared to virtual machines.   Option D Server-based virtualization is a broader term but does not specifically refer to the use of a hypervisor, making it less precise.   Option E Network virtualization is incorrect because it involves the abstraction of network resources, not operating systems.
