Answer - D - FTP protocol should be replaced by the Secure FTP protocol.

Key Takeaway: The vulnerability associated with using the FTP protocol is that the user ID and password aren’t encrypted and are subject to packet capture. This creates a major security breach, especially if you’re connecting to an FTP server across the Internet. Secure FTP (S/FTP) is accomplished using a protocol called Secure Shell (SSH), a type of tunneling protocol that allows access to remote systems in a secure manner. TFTP is a trivial version of FTP. HTTP and DNS cannot provide the same functionalities as the FTP protocol.
