A network engineer is deploying a high-availability infrastructure using Type 1 hypervisors in an enterprise data center. Which two statements accurately describe the operational and structural characteristics of Type 1 hypervisors and their virtual network components? (Select two.)
- The hypervisor runs directly on the host hardware substrate without requiring an underlying general-purpose operating system.Answer
- Virtual switches inside the hypervisor forward Layer 2 frames between local virtual machines and map traffic to physical network interface cards.Answer
- CThe hypervisor functions as a software application executed within a general-purpose host operating system such as Windows or Linux.
- DVirtual switches run Spanning Tree Protocol across physical uplinks to participate in root bridge elections with upstream physical switches.
Answer
The correct statements are that the hypervisor runs directly on the host hardware substrate without requiring an underlying general-purpose operating system, and that virtual switches inside the hypervisor forward Layer 2 frames between local virtual machines and map traffic to physical network interface cards.
Type 1 hypervisors (such as VMware ESXi or Cisco UCS hypervisors) operate directly on bare-metal server hardware without requiring a host operating system layer. Inside the hypervisor environment, software-defined virtual switches perform Layer 2 forwarding between virtual machine virtual NICs (vNICs) and multiplex frame traffic onto physical network interface card (pNIC) uplinks.
