Which operation allows executing scripts in Action operations?

The option "Run SSH Script file" is the correct choice because it specifically refers to an operation that is designed to execute scripts on a remote system via SSH (Secure Shell). This operation allows for running command-line scripts directly, which can be crucial for automation and management tasks during the Discovery process in ServiceNow. Using this operation, you can effectively manage devices and retrieve necessary information in a streamlined manner.

In contrast, the other operations do not specifically imply script execution. For instance, "Put file" typically relates to transferring a file to a target system rather than executing it. "Transform file" involves changing the format or structure of a file, and "Download file" indicates retrieving a file from a host without executing it. Therefore, these options do not serve the purpose of executing scripts in the context described in the question, making "Run SSH Script file" the most appropriate operation for scripting tasks.
