Which protocol is used for facilitating remote command execution on hosts during discovery?

The correct answer is SSH, which stands for Secure Shell. SSH is widely used for secure remote command execution on hosts, especially in Unix-like operating systems. During the discovery process, SSH allows the ServiceNow Discovery to securely connect to a remote machine, execute commands, and gather information about the system configuration and services running on it.

This capability is crucial for discovering various attributes of a host, such as installed software, running processes, and network interfaces. The secure nature of SSH also ensures that the data exchanged between the ServiceNow instance and the target machines is protected against eavesdropping and tampering, making it a preferred method for remote command execution.

In contrast, while WMI (Windows Management Instrumentation) is used for Windows-based systems and can facilitate similar discovery operations, it is not as universally applicable as SSH across different operating systems. SNMP (Simple Network Management Protocol) is primarily utilized for monitoring and managing network devices rather than for executing commands. HTTP (HyperText Transfer Protocol) is typically used for web communication and would not serve the purpose of executing remote commands in the same secure and efficient manner as SSH.
