Question

Difficulty: MediumNetwork Components Roles and Functions

A network architect is designing a virtualized data center infrastructure utilizing bare-metal hypervisors and virtual switches. Which two statements accurately describe the roles and functions of these components? (Choose two.)

  1. The Type 1 hypervisor runs directly on the underlying server hardware without requiring a host operating system.Answer
  2. The virtual switch handles Layer 2 frame forwarding between virtual machines configured on the same host.Answer
  3. C
    A Type 1 hypervisor operates as an application layer service installed on top of an existing general-purpose operating system.
  4. D
    A virtual switch inherently divides broadcast domains at Layer 3 without needing VLAN configurations or external routers.

Answer

The correct statements are that the Type 1 hypervisor runs directly on physical server hardware without requiring a host operating system, and that the virtual switch handles Layer 2 frame forwarding between virtual machines on the same host.
Type 1 hypervisors install directly onto physical hardware without requiring a host OS, providing efficient allocation of hardware resources to virtual machines. The internal virtual switch operates at Layer 2 to manage frame forwarding between virtual machines connected to the same virtual network.

Step-by-Step Solution

1
Analyze the architecture of Type 1 hypervisors
Confirm that Type 1 hypervisors (bare-metal) install directly on the hardware platform without an intermediate operating system.
Direct access to physical hardware provides higher efficiency and lower processing overhead for enterprise virtualization.
2
Examine the role of software virtual switches inside hypervisors
Confirm that virtual switches perform Layer 2 forwarding for guest virtual machine network traffic on the host.
Virtual switches mimic physical Layer 2 switches to connect virtual network interface cards (vNICs).
3
Evaluate distractor statements for conceptual misconceptions
Identify that operating on top of a host OS is characteristic of Type 2 hypervisors, and that virtual switches operate at Layer 2 rather than separating broadcast domains at Layer 3 automatically.
Hypervisor classification and OSI layer responsibilities must be strictly distinguished.
