Bias Analysis

Bias Types:
⚠️ windows_first
⚠️ powershell_heavy
⚠️ missing_linux_example
⚠️ windows_tools
Summary:
The documentation exhibits a strong Windows bias in the testing and validation sections. All VM creation examples use Windows images, and all instructions for configuring and testing DNS resolution are written exclusively for Windows (PowerShell commands, Windows firewall, and output). There are no Linux VM creation examples, nor are there any Linux shell or firewall commands provided. The documentation assumes the user is operating in a Windows environment for all post-deployment steps.
Recommendations:
  • Provide parallel Linux examples for VM creation (e.g., using --image UbuntuLTS) and show both Windows and Linux VM creation commands.
  • Include instructions for configuring the firewall to allow ICMP on Linux VMs (e.g., using ufw or firewalld).
  • Show how to test DNS resolution from a Linux shell (e.g., using ping, dig, or nslookup in bash).
  • Present both Windows and Linux command outputs for DNS resolution tests.
  • Explicitly mention that the steps apply to both Windows and Linux, and clarify any OS-specific differences.
  • Consider alternating the order of Windows and Linux examples, or presenting them side-by-side to avoid 'windows_first' bias.
