A network engineer is configuring a virtualized data center host to support multiple enterprise server workloads. The installation utilizes a bare-metal (Type 1) hypervisor to manage virtual machine (VM) compute and virtual switch networking features. Which statement accurately describes the operational role and architecture of a Type 1 hypervisor in this deployment?
- AIt executes as a software application on top of an existing host operating system, passing virtual machine network requests through the host OS stack.
- It runs directly on the bare-metal physical hardware, managing hardware resources and virtual switch packet forwarding without an underlying host operating system.Cevap
- CIt relies entirely on connected upstream physical Layer 2 switches to perform frame forwarding between virtual machines hosted on the same physical server.
- DIt utilizes Layer 2 neighbor discovery protocols such as CDP or LLDP to dynamically assign IPv4 addressing and default gateways to guest virtual machines.
Cevap
A Type 1 hypervisor runs directly on the bare-metal physical hardware, managing hardware resources and virtual switch packet forwarding without an underlying host operating system.
A Type 1 hypervisor (such as Cisco UCS ESXi or KVM) installs directly onto the bare-metal hardware of a host machine. It provides direct hardware control, lower latency, and embedded software vSwitching capabilities to switch network frames between guest virtual machines and uplink to physical network infrastructure.
