In virtualization, what is the primary role of a hypervisor?

A hypervisor, also known as a Virtual Machine Monitor (VMM), is a key component in virtualization that allows multiple virtual machines (VMs) to run on a single physical server by managing the allocation of resources such as CPU, memory, and storage. Hypervisors come in two types: Type 1 (bare-metal) runs directly on the hardware, while Type 2 runs on top of a host operating system. This abstraction layer enables efficient utilization of physical resources while maintaining isolation between VMs. Option A is incorrect because hypervisors manage virtual machines, not just physical servers. Option B is incorrect because security is not the primary function of hypervisors; they manage VMs. Option D is incorrect because hypervisors actually enhance scalability by allowing multiple VMs to share resources efficiently. Option E is incorrect because hypervisors are focused on virtualization, not on automating software deployment (which is a role more closely associated with CI/CD tools).
