Which two resources are abstracted by the hypervisor and presented to virtual machines?

The hypervisor plays a critical role in virtualization by abstracting and managing physical resources and presenting them to virtual machines (VMs) as virtual resources. Among the resources listed, CPU and memory are fundamental components that the hypervisor effectively abstracts.

The CPU abstraction allows virtual machines to utilize processing power from the physical CPU. The hypervisor manages how many virtual CPUs are allocated to each VM and handles scheduling of CPU time so that multiple VMs can run simultaneously on the same physical hardware without interfering with one another.

Similarly, memory abstraction enables each virtual machine to operate as if it has its own dedicated memory. The hypervisor divides the available physical memory and allocates portions to individual VMs, providing each with an isolated environment to operate in.

Other options mention resources that, while they can relate to VMs, are not directly managed or abstracted by the hypervisor in the same way. Libraries, applications, desktops, networks, and storage can all interact with and be utilized by virtual machines, but they are often managed at higher levels, such as through the virtual machine's operating system or specific virtual services, rather than being immediately abstracted by the hypervisor itself. Thus, CPU and memory are the correct answers, as they are the primary resources that
