FTPS runs on which protocol?
TCP 22
UDP 69
TCP 20
TCP/UDP 21
20=FTP-data, 21=FTP=control, 22=SFTP (ssh), 69=TFTP, 989=FTPS-data, 990=FTPS-control. EDIT: Technically speaking, FTPS can run on either TCP/UDP 21 (explicit SSL) or TCP/UDP 990 (implicit SSL). While the accepted nowadays is to use 21 as it is more secure, simply asking "which one in general" would make this a multiple answer question. Please modify accordingly.
