A technician needs to connect to a network switch in a remote location.
The technician wants to make sure the data passed over the wire is encrypted so it cannot be read by someone using a sniffer.
Which of the following connection protocols should the technician use?

To make sure that the data passed over the wire is encrypted and cannot be read by someone using a sniffer, the technician should use SSH (Secure Shell) protocol for connecting to the remote network switch.
SSH is a secure network protocol that provides a secure channel over an unsecured network, such as the Internet. It uses encryption to protect the confidentiality and integrity of data transmitted between devices. SSH provides secure authentication and secure communication between two networked devices, such as a computer and a server or a network switch.
Telnet, on the other hand, is an older, less secure protocol that transmits data in plain text, making it susceptible to interception and sniffing. Telnet should not be used over a public network like the Internet as it can be easily intercepted and read by attackers.
SMB (Server Message Block) is a file sharing protocol used in Windows networks. It does not provide encryption for data transmission, and so it is also susceptible to sniffing.
HTTP (Hypertext Transfer Protocol) is the protocol used for transferring data over the World Wide Web. Like Telnet and SMB, HTTP does not provide encryption, and so it is not a secure protocol for transmitting sensitive data.
SFTP (Secure File Transfer Protocol) is a secure alternative to FTP (File Transfer Protocol). It uses SSH to provide a secure channel for transmitting files between devices. While SFTP is a secure protocol for file transfer, it is not a protocol for connecting to network devices like switches.
In summary, the best protocol to use for connecting to a network switch in a remote location while ensuring that data passed over the wire is encrypted and secure is SSH.
