What default port does SFTP use?

• A. 21
• B. 22
• C. 990
• D. 80

Answer: (B)

SFTP, or Secure File Transfer Protocol, operates over a default port of 22. This is significant because port 22 is also the default port for SSH (Secure Shell), which SFTP uses for secure communications. The use of this port allows SFTP to leverage the security features inherent in the SSH protocol, providing a secure means to transfer files over a network. Understanding the default operation of SFTP on port 22 is important for network configuration, firewall settings, and ensuring secure file transfers, as using the correct port is essential for effective connectivity. Other options like port 21 are associated with FTP (File Transfer Protocol), while port 990 is used for FTPS (FTP Secure), and port 80 is the default for HTTP (Hypertext Transfer Protocol). These ports serve different protocols and functions, reinforcing the importance of recognizing the role of port 22 specifically for SFTP.
