Question

Difficulty: MediumType 1 and Type 2 Hypervisors

A network administrator is evaluating virtualization architectures to host high-performance infrastructure services in an enterprise server rack. Which of the following statements accurately describe the operational characteristics of a Type 1 hypervisor compared to a Type 2 hypervisor? (Select TWO.)

  1. It deploys directly onto physical server hardware without requiring an underlying host operating system.Answer
  2. It provides higher hardware access efficiency and lower latency for guest virtual machines.Answer
  3. C
    It executes as a traditional application layer within a conventional host desktop operating system.
  4. D
    It relies on host OS system calls and kernel drivers to process storage and network I/O operations.

Answer

Type 1 (bare-metal) hypervisors install directly on the host's physical hardware without needing a pre-existing host operating system, which provides lower latency and improved performance due to direct control over hardware resources.
Type 1 hypervisors operate directly on bare-metal physical hardware, bypassing the need for a general-purpose host operating system. This architectural efficiency provides guest virtual machines with lower latency and higher performance.

Step-by-Step Solution

1
Analyze the core structural layer of a Type 1 hypervisor.
Identify that Type 1 hypervisors sit directly above hardware without an intervening host OS layer.
Bare-metal hypervisors manage physical CPU, memory, and storage directly.
2
Evaluate performance impact of Type 1 vs Type 2 hypervisors.
Recognize that avoiding host OS translation layers reduces latency and resource overhead.
Direct hardware access optimizes resource utilization for enterprise server workloads.
