Difficulty: MediumNetwork Components Roles and Functions

An enterprise network team is deploying a virtualized data center infrastructure to support high-performance database workloads. The design requires a hypervisor deployment that operates directly on bare-metal server hardware without relying on an underlying host operating system to maximize resource efficiency and reduce overhead. Which hypervisor architecture meets these requirements, and what is its primary operational characteristics?

  1. A Type 1 hypervisor, which installs directly on the bare-metal hardware and manages guest operating systems directly.Answer
  2. B
    A Type 2 hypervisor, which installs as an application layer on top of a conventional host operating system to manage virtual resources.
  3. C
    A Layer 2 switch operating with PortFast, which isolates broadcast domains across bare-metal server interfaces.
  4. D
    A Layer 2 discovery agent, which uses CDP/LLDP TLVs to dynamically allocate physical hardware CPU cores to virtual machines.

Answer

A Type 1 hypervisor, which installs directly on the bare-metal hardware and manages guest operating systems directly.
The correct option correctly identifies a Type 1 hypervisor, also known as a bare-metal hypervisor. It runs directly on host server hardware, giving guest virtual machines direct access to compute and hardware resources while minimizing performance overhead.

Step-by-Step Solution

1
Analyze the operational requirements provided in the scenario.
The requirements demand a hypervisor that runs directly on server hardware (bare-metal) without an underlying host operating system to eliminate unnecessary latency and OS overhead.
Enterprise virtualized server environments hosting high-performance workloads require direct hardware abstraction and direct access to CPU, memory, and storage.
2
Distinguish between hypervisor types and network device roles.
Type 1 (bare-metal) hypervisors sit directly on host hardware. Type 2 (hosted) hypervisors require a host OS. Switches and discovery protocols handle network traffic forwarding and discovery, not host server virtualization.
Understanding component roles ensures selecting the architecture designed for bare-metal virtualization.
