The cmdlet that lists existing Windows Firewall rules on Windows Server 2012 R2 is Get-NetFirewallRule. This cmdlet is part of the NetSecurity module and is specifically designed to retrieve and display firewall rules that are configured on the system.

When you use Get-NetFirewallRule, it provides a comprehensive overview of all the firewall rules, including their names, display names, enabled status, and other relevant properties. This command is essential for network administrators who need to audit or manage the firewall settings on a server.

The other options do not exist as valid cmdlets in Windows PowerShell for this purpose. For instance, Show-NetFirewallRule, List-NetFirewallRules, and View-NetFirewallRules do not correspond to any cmdlets provided by Windows PowerShell for managing Windows Firewall. Instead, they illustrate possible variations of cmdlet naming conventions but do not perform the intended function. Understanding the proper cmdlet is crucial for effective firewall management and troubleshooting in Windows Server environments.
