An administrator needs to remotely manage network devices securely over an untrusted network. Which protocol should be used to ensure that both authentication credentials and management data are encrypted during transmission?
HTTP
Console port
Telnet
Secure Shell
Secure Shell (SSH) should be used because it encrypts both authentication credentials and management data, providing secure remote access to network devices. Telnet transmits data in plaintext, making it insecure. HTTP is used for web interfaces but does not encrypt data by default. The console port provides direct local access and is not used for remote management over a network.
