Difficulty: MediumNetwork Components Roles and Functions

A network administrator is deploying a virtualized server environment using bare-metal Type 1 hypervisors connected to an enterprise campus network. Which two operational roles and functions are performed directly by the Type 1 hypervisors in this infrastructure? (Select two.)

  1. Abstracting underlying physical hardware resources to allocate vCPUs, system memory, and virtual network interfaces directly to hosted virtual machinesAnswer
  2. Facilitating Layer 2 frame forwarding between virtual machines residing on the same physical host via an embedded virtual switchAnswer
  3. C
    Operating as an application software layer on top of an existing general-purpose host operating system such as Windows Server or Linux
  4. D
    Terminating Layer 3 broadcast domains and making IP packet forwarding decisions between subnets across physical servers

Answer

The two correct functions performed directly by a Type 1 hypervisor are abstracting physical hardware resources to allocate vCPUs, memory, and virtual network interfaces to guest virtual machines, and facilitating Layer 2 frame forwarding between virtual machines on the same physical host through an integrated virtual switch.
Type 1 bare-metal hypervisors run directly on server hardware, allowing efficient hardware abstraction and direct distribution of vCPU, memory, and virtual interfaces to guest VMs. In addition, hypervisors feature built-in Layer 2 virtual switches (vSwitches) to forward frames locally between virtual machines sharing the same physical host.

Step-by-Step Solution

1
Identify the architectural deployment model of a Type 1 hypervisor.
A Type 1 hypervisor runs directly on the bare-metal physical hardware without relying on a underlying general-purpose host operating system.
This bare-metal positioning gives the hypervisor direct control over hardware virtualization.
2
Analyze the resource management and network forwarding capabilities built into the hypervisor.
The hypervisor partitions physical CPU, RAM, and NICs into virtual components for VMs and includes a virtual switch (vSwitch) to forward Layer 2 frames locally.
Local VM-to-VM traffic within the same host is bridged at Layer 2 by the internal vSwitch, while inter-subnet Layer 3 routing is handed off to network infrastructure devices.
