A.

The most likely protocol that the technician will use to connect securely to a Linux-based network appliance in a remote datacenter is SSH (Secure Shell).

SSH is a cryptographic network protocol that provides secure communication over an unsecured network. It uses encryption to protect the contents of the communication, as well as authentication to ensure that the communication is only between authorized parties.

SFTP (Secure File Transfer Protocol) is a protocol that is used to transfer files securely over a network, but it is not typically used for connecting to remote devices like network appliances.

RDP (Remote Desktop Protocol) is a protocol that is used to connect to and control a remote desktop or server, but it is typically used on Windows-based systems, not Linux-based systems.

Telnet is a protocol that is used to access and manage remote devices, but it is an unencrypted protocol, so it is not recommended for use over unsecured networks.

Therefore, SSH is the best option for connecting securely to a Linux-based network appliance in a remote datacenter.
