What are two roles of a hypervisor in a data center? (Choose two.)

The correct answer is A. provides management for physical network devices C. virtualizes bare-metal server resources and provides resources to virtual machines. A hypervisor's core functions include virtualizing bare-metal server resources for virtual machines and managing the host's physical network interfaces which connect to physical network devices.

Why each option

A hypervisor's core functions include virtualizing bare-metal server resources for virtual machines and managing the host's physical network interfaces which connect to physical network devices.

Aprovides management for physical network devicesCorrect

A hypervisor configures and manages the physical network adapters (NICs) on the bare-metal server, including aspects like VLAN tagging, network teaming, and connecting virtual switches to these physical interfaces, which are essential for integrating virtual machines with the physical network devices like switches.

Bprovides management for physical servers

A hypervisor runs on a physical server; managing the server hardware itself (e.g., power, firmware) is typically handled by BMCs or server management software, not directly by the hypervisor.

Cvirtualizes bare-metal server resources and provides resources to virtual machinesCorrect

A hypervisor's fundamental role is to abstract and virtualize the underlying physical hardware resources-CPU, memory, storage, and network interfaces-from a bare-metal server. It then allocates these virtualized resources to multiple isolated virtual machines, enabling them to run concurrently on a single physical host.

Dpartitions physical servers into multiple virtual machines

While a hypervisor does partition servers, choice C provides a more complete and accurate description of the virtualization process and resource allocation by also mentioning resource provisioning.

Evirtualizes network devices and provides resources to virtual devices

A hypervisor primarily virtualizes server hardware; virtualizing network devices (like routers or firewalls) is a function of network virtualization platforms, not the core role of a server hypervisor itself.
