Which of the following TCP ports is used to provide the SMB protocol without NetBIOS?

The SMB protocol (Server Message Block) is used for providing shared access to files and printers.

Historically, SMB ran on top of NetBIOS over TCP/IP using port 139.

SMB can also run directly over TCP/IP without the NetBIOS layer, which uses port 445.

Therefore, TCP port 445 is used to provide the SMB protocol without NetBIOS.
