What is a primary function of a hypervisor in virtual machine environments? 

A hypervisor , also known as a virtual machine monitor (VMM), is responsible for creating, managing, and monitoring virtual machines (VMs). It allocates system resources such as CPU, memory, and storage to individual virtual machines while maintaining isolation between them. There are two types of hypervisors: Type 1, which runs directly on the hardware (bare-metal), and Type 2, which runs on an operating system. Hypervisors are foundational to virtual environments, enabling efficient resource utilization and scalability. Why other options are wrong: a) It manages the file system across multiple virtual machines : While a hypervisor manages VMs, it does not directly manage file systems within those VMs. b) It enables communication between physical and virtual processors : The hypervisor allocates processor resources, but direct communication between physical and virtual processors is not its role. d) It functions as a firewall for virtual machines : Firewalls can be configured for security, but theyare separate from the core function of a hypervisor. e) It handles data encryption within virtual machine environments : Encryption is typically managed by separate tools, not the hypervisor itself.
