Zorluk: OrtaVirtualization Security Considerations and Network Configurations

A network administrator is deploying a virtual machine (VM) on a desktop computer to run a network management service. The service requires the VM to obtain its own IP address directly from the physical network's DHCP server and be fully accessible by other physical devices on the local subnet. Which virtual network adapter mode should the administrator configure?

  1. A
    NAT (Network Address Translation) mode
  2. Bridged modeCevap
  3. C
    Host-only mode
  4. D
    Internal mode

Cevap

Bridged mode should be configured because it binds the virtual adapter directly to the physical network adapter, enabling the guest virtual machine to receive an IP address from the physical DHCP server and communicate as an independent host on the physical subnet.
Bridged mode creates a direct connection between the virtual network interface card (vNIC) and the physical host's network interface card (NIC). This allows the virtual machine to operate as an independent device on the physical network, obtaining its own IP address from the physical network's DHCP server and accepting incoming connections from physical network hosts.

Adım Adım Çözüm

1
Analyze the virtual machine networking requirements
The virtual machine must obtain an IP address from the external physical DHCP server and allow direct inbound access from physical network hosts.
Different virtual network modes establish distinct boundaries between the guest operating system, host operating system, and physical network.
2
Evaluate Bridged mode functionality
Bridged mode connects the virtual network adapter directly to the physical network interface layer.
This allows the virtual machine to participate directly on the physical network, request an IP address via DHCP, and receive direct incoming traffic.
3
Eliminate non-matching networking modes
NAT translates traffic behind host IP, while Host-only and Internal modes isolate traffic from the physical network entirely.
None of the isolated or address-translated modes satisfy the requirement for direct physical network visibility and DHCP lease allocation.
