Final answer:
HTTPS is the most secure method for hosting streaming video files for remote users, encrypting data to prevent eavesdropping.
Step-by-step explanation:
The best method for securely hosting streaming video files is HTTPS (Hypertext Transfer Protocol Secure). HTTPS encrypts the data between the server and the client, ensuring that remote users can stream videos while protecting the data from eavesdropping or interception. In comparison, FTP (File Transfer Protocol) is not secure by default, Telnet is an unencrypted and therefore insecure protocol for text-based communication, and SNMP (Simple Network Management Protocol) is used for network management rather than secure file transfer or streaming.
