What is the sole function of the MID Server?

The primary function of the MID Server in ServiceNow is to execute work requests and return results to the ServiceNow instance. The MID Server acts as a communication platform between ServiceNow and external systems, allowing the Discovery process to efficiently gather information from various network devices and applications.

By executing work requests, such as running discovery probes or performing SSH commands, the MID Server collects configuration item data, which is critical for maintaining an accurate Configuration Management Database (CMDB). Once the data collection is complete, the MID Server returns the results back to ServiceNow for processing and analysis. This seamless operation facilitates a more accurate representation of the enterprise's IT infrastructure.

Other options describe functions that are not aligned with the core purpose of the MID Server, which revolves specifically around executing tasks and relaying data, emphasizing its role as an intermediary between on-premise systems and the cloud-based ServiceNow platform.
