A system administrator is selecting virtualization software for a server host that will run latency-sensitive production databases in an enterprise datacenter. The administrator decides to deploy a Type 1 (bare-metal) hypervisor instead of a Type 2 (hosted) hypervisor. Which of the following statements correctly describe the architectural characteristics and operational advantages of a Type 1 hypervisor? (Select TWO).
- It installs directly on the host hardware hardware layer without requiring a baseline host operating system.Answer
- BIt runs as an application process managed inside a general-purpose host operating system such as Windows or macOS.
- It eliminates performance overhead caused by host OS resource consumption, offering lower latency for guest virtual machines.Answer
- DIt relies on host operating system device drivers to translate hardware calls from guest virtual machines.
Answer
The statements describing direct bare-metal installation on host hardware and the elimination of host operating system performance overhead correctly characterize Type 1 hypervisors.
Type 1 hypervisors (such as VMware ESXi or Microsoft Hyper-V installed on bare metal) interact directly with physical hardware without needing a general-purpose host OS. This direct control eliminates the latency and resource consumption of an underlying host operating system, providing optimal performance for enterprise virtual machines.
