Which port needs to be open for inbound connections to use WinRM for Azure VMs?

• A. 80
• B. 443
• C. 5985
• D. 3389

Answer: (C)

For Windows Remote Management (WinRM) to function properly, it relies on specific ports for communication. In the context of Azure VMs, the port that needs to be open for inbound connections to enable WinRM is 5985 for HTTP and 5986 for HTTPS. These ports are specifically designated for WinRM operations, allowing remote management capabilities.

Opening port 5985 ensures that standard WinRM traffic is permitted, allowing administrators to execute commands, access management features, and perform remote tasks without needing to directly log into the VM. While other ports such as 80 and 443 relate to HTTP and HTTPS traffic more generally, they are not specific to WinRM. Port 3389 is used for Remote Desktop Protocol (RDP) but does not facilitate WinRM communications.

In summary, having port 5985 open is crucial for enabling the WinRM service on Azure VMs, facilitating secure and reliable remote management capabilities.
