As a network administrator, you are tasked with setting up a remote connection to configure a new server. To ensure that the connection is encrypted, you decide to use a protocol that operates on the default port 22. Which protocol should you employ for secure command-line access to the remote server?
SSH
Telnet
HTTPS
HTTP
Secure Shell (SSH) is a cryptographic network protocol used for secure data communication, specifically for providing secure command-line access to a remote server. It operates on the default TCP port 22. SSH ensures data integrity and confidentiality by encrypting the entire session between the client and server. Telnet also provides command-line access but is incorrect for this scenario because it is insecure and transmits data in plaintext. HTTP and HTTPS operate on ports 80 and 443, respectively, and facilitate web communication rather than command-line access.
