What is the primary function of Secure Shell (SSH)?

File transfer between systems
Configuration of network devices
Text-based control communication with encryption
Database management

The correct answer is: Text-based control communication with encryption

The primary function of Secure Shell (SSH) is to provide a secure, encrypted channel over an unsecured network. It is commonly used for securely accessing and managing network devices and servers through a command-line interface. SSH encrypts the session data, ensuring that any information transmitted between the client and the server remains private and secure from eavesdropping or tampering. While SSH can support file transfer through protocols like SFTP or SCP, its main purpose aligns with enabling secure text-based communication. This functionality extends to remotely executing commands and performing administrative tasks on devices securely. The focus of SSH is on establishing a secure communication channel, making it an essential tool for system administrators and network engineers working in environments where security is paramount.
