What type of FTP access allows users to access files if they know the file name but not to list directory contents?

• A. Blind FTP
• B. Anonymous FTP
• C. Restricted FTP
• D. Secure FTP

Answer: (A)

The correct answer, indicating the type of FTP access that enables users to access files by knowing the file name while restricting their ability to list the contents of directories, is known as Blind FTP. In this context, Blind FTP provides a more controlled access method, focusing on file retrieval without giving users the ability to navigate or see the directory structure. This can enhance security by limiting information visible to users, thereby preventing them from potentially finding sensitive information or accessing files that they shouldn't be able to see. In relation to the other options, Anonymous FTP typically allows users to log in without a specific user account (often using "anonymous" as the username) and generally allows them to both list directory contents and access files within those directories. Restricted FTP could imply limitations that might be imposed by an administrator, but it does not specifically point to the feature of preventing directory listings. Secure FTP refers to protocols that encrypt the data transferred, focusing on security rather than the access structure. Thus, these other options don't represent the specific characteristics of limited directory access tied to knowledge of file names that define Blind FTP.
