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

A133

B138

C139

D386

E445

Show Suggested Answer

Suggested Answer: E

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.

I bet the correct answer is 'all of the above' just to mess with us.

I believe it's E) 445 because NetBIOS is not needed for SMB protocol on that port.

Wait, does SMB even work without NetBIOS? I'm scratching my head here.
