Why each option
To replace insecure Telnet for remote terminal management in a secure manner, SSH is the appropriate protocol as it provides encrypted communication.
Remote Desktop Protocol (RDP) provides a graphical user interface (GUI) for remote access, which is different from Telnet's terminal-based interaction.
Console access refers to direct physical access to the server's keyboard and monitor, which is not a remote management method.
Secure Shell (SSH) is a cryptographic network protocol that allows secure remote login to computers over an unsecured network. It encrypts all traffic, including passwords, preventing eavesdropping and man-in-the-middle attacks, thus replacing Telnet's functionality securely for remote terminal access.
Secure File Transfer Protocol (SFTP) is used for secure file transfer, not for remote terminal access or command-line management.
