A systems administrator has created a guest VM on a hypervisor host. The guest VM would need to have a dynamic IP address assignment on the same subnet as the hypervisor. Which of the following…

The correct answer is A. Bridging. Bridged networking connects a guest VM directly to the physical network so it can obtain a DHCP-assigned IP address on the same subnet as the hypervisor host.

Question

A systems administrator has created a guest VM on a hypervisor host. The guest VM would need to have a dynamic IP address assignment on the same subnet as the hypervisor. Which of the following network connectivity types should the administrator configure?

Why each option

Bridged networking connects a guest VM directly to the physical network so it can obtain a DHCP-assigned IP address on the same subnet as the hypervisor host.

ABridgingCorrect

Bridged networking attaches the guest VM's virtual NIC to the host's physical NIC at Layer 2, making the VM appear as a distinct device on the physical network segment. This allows the existing DHCP server on that subnet to assign the guest a dynamic IP address in the same range as the hypervisor, satisfying both requirements in the question.

BNAT

NAT places the guest VM on a separate private subnet and translates its traffic through the host's IP address, so the VM cannot share the same subnet as the hypervisor.

CVLAN

A VLAN is a Layer 2 network segmentation mechanism, not a VM-to-network connectivity mode, and does not control how the VM obtains an IP address relative to the host.

DSpoofing

Spoofing is a security attack technique involving falsified identity information and is not a valid or configurable VM network connectivity type.
