An IT technician is configuring network adapters and security isolation rules for several virtual machines running on a desktop hypervisor. Match each virtual network configuration mode to the operational scenario or connectivity requirement that best describes its traffic profile.
- Bridged NetworkingThe VM receives a unique IP address on the physical network subnet and is fully reachable by physical network nodes.
- Network Address Translation (NAT)The VM shares the host system's IP address for outbound traffic to external networks but is shielded from unsolicited external inbound traffic.
- Host-Only NetworkingThe VM can communicate only with the host OS and other VMs configured on the same private virtual interface, with no routing to external networks.
- Internal / Private Virtual SwitchThe VM can communicate only with other VMs on the same hypervisor host, completely isolated from both the host OS network stack and external networks.
Answer
Bridged Networking corresponds to receiving a unique IP on the physical subnet; NAT corresponds to sharing the host IP for outbound traffic while blocking external inbound traffic; Host-Only corresponds to communicating exclusively with the host OS and peer VMs; Internal/Private Switch corresponds to isolating traffic strictly to peer VMs while excluding the host OS.
Each virtual network adapter mode enforces specific boundary conditions. Bridged mode places the guest directly onto the physical network subnet. NAT mode translates outbound requests through the host IP to provide internet access without exposing inbound interfaces. Host-Only mode restricts connectivity to a closed network between the host OS and guest VMs. Internal/Private mode completely isolates the guest VMs from both external networks and the host OS network stack.
