What is a requirement for socket reuse in FTP transfers?

• A. It's available only with FTP
• B. It's optional in all modes
• C. It's available only with FTPS
• D. It's required in all connections

Answer: (C)

In the context of FTP (File Transfer Protocol) and its secure variant FTPS (File Transfer Protocol Secure), socket reuse refers to the ability to use the same network socket for multiple FTP commands after establishing a connection. The correct answer highlights that socket reuse is a feature specifically associated with FTPS and not with standard FTP. FTPS incorporates security measures that are not part of traditional FTP, such as encryption and secure authentication, which can impact how connections are managed and reused. The implementation of socket reuse in FTPS allows for maintaining an efficient communication channel while ensuring that sensitive data is transmitted securely. While socket reuse may be a feature that can be utilized in certain configurations of FTP, it is not a requirement or inherent aspect of the protocol itself. Therefore, socket reuse in FTP doesn’t have the same foundational necessity as it does in FTPS, where secure connections necessitate more structured management of sessions and connections. Understanding the context of these protocols and their operational criteria helps clarify the importance of secure connections in transferring data efficiently and safely.
