Which port and protocol is commonly used by SMB/CIFS file sharing on Windows?

Explanation:
The key idea is that Windows file sharing with SMB/CIFS runs over TCP using port 445. Modern Windows implementations connect SMB directly over TCP on 445, without relying on NetBIOS on 139, making 445 the standard port for SMB/CIFS file sharing. The other ports correspond to different services—3389 is for Remote Desktop Protocol, 1433 is the default port for Microsoft SQL Server, and 27017 is the default port for MongoDB—so they don’t relate to SMB/CIFS file sharing.
