Question

Difficulty: HardNetwork Components Roles and Functions

A network architect is designing a high-availability infrastructure for an enterprise campus network. The design replaces legacy distribution switches with Layer 3 switches and deploys a bare-metal Type 1 hypervisor host to support core virtualized services such as DNS, DHCP, and IPAM. Which of the following statements correctly describe the operational roles and traffic handling behavior of these components? (Select TWO.)

  1. The Layer 3 switch terminates VLAN broadcast domains at the distribution layer by performing IP routing between IP subnets.Answer
  2. The Type 1 hypervisor runs directly on the bare-metal host hardware to allocate hardware resources to virtualized infrastructure services without a host operating system layer.Answer
  3. C
    The Layer 3 switch consolidates all connected VLAN interfaces into a single unified broadcast domain to enable high-speed hardware frame switching without Layer 3 processing.
  4. D
    The Type 1 hypervisor requires a guest host operating system (such as Windows or Linux) installed first on the physical server to mediate control plane instructions to physical CPU and memory resources.

Answer

The correct statements are that the Layer 3 switch terminates VLAN broadcast domains at the distribution layer by routing between IP subnets, and the Type 1 hypervisor runs directly on bare-metal hardware without a host operating system.
Layer 3 switches establish Layer 3 boundaries between subnets, terminating broadcast domains for each VLAN while routing traffic between them. Type 1 hypervisors run directly on the physical hardware (bare metal), providing high performance and direct resource management for server virtual machines.

Step-by-Step Solution

1
Analyze Layer 3 switch operational roles.
Layer 3 switches isolate broadcast domains per VLAN and perform inter-VLAN routing at Layer 3.
Layer 2 switches isolate collision domains but forward broadcast frames within a VLAN. Adding Layer 3 capabilities creates distinct broadcast domain boundaries per subnet.
2
Evaluate hypervisor architecture types.
Type 1 hypervisors operate directly on physical bare metal, while Type 2 hypervisors run inside a conventional host operating system.
Bare-metal deployment minimizes latency and resource overhead for enterprise virtualized network services.
