Answer:
d) All of the mentioned

SSH (Secure Shell) provides multiple authentication methods to ensure secure access 🔐 to remote systems. The most common ones include:

Public-key Authentication: This method uses a pair of cryptographic keys, a public key stored on the server and a private key kept by the user 🔑. It ensures that only users with the correct private key can log in.

Host-based Authentication: In this method, a host verifies the identity of another trusted host 🖥️. This is useful in environments where multiple systems need secure interconnection.

Password Authentication: Users can also log in using traditional passwords 🔒, though this method is less secure compared to public-key authentication.

SSH supports all of these methods, allowing flexibility based on the security needs of the system!
