Refer to the exhibit. Which protocol should be used to encrypt a client connection that signs in to the router remotely to make common configuration changes?

Secure Shell (SSH) provides an encrypted, authenticated connection for remote command-line access, making it the standard and most secure protocol for administrators to sign in to a router and make configuration changes.

FTPS (FTP Secure) is a protocol for secure file transfer, not for interactive remote command-line access or router configuration.

SCP (Secure Copy Protocol) is used for secure file transfer, not for establishing an interactive session to configure a router.

SFTP (SSH File Transfer Protocol) is also a secure file transfer protocol built on SSH, but it does not provide an interactive shell for remote router configuration.
