What is the purpose of the 'discovery_id' in a discovery log?

You are a ServiceNow Discovery administrator. After a recent discovery run, you notice that a Linux server CI has an incorrect operating system version attribute. You want to manually correct this value in the CMDB. Which module should you use to edit the CI record?

You are a ServiceNow Discovery administrator for a large enterprise. You have configured Discovery to populate the CMDB with data from multiple sources, including ServiceNow Discovery, SCCM, and a third-party asset management system. You need to ensure that the CMDB is not polluted with duplicate CIs and that the most authoritative data source wins when there are conflicts. Which feature should you use to achieve this?

A technician reports that Discovery is updating the 'Last discovered' field, but the 'Operational status' is not changing as expected. Where should you investigate the mapping of Discovery data to the CMDB?

During a Discovery run, a Windows server is discovered and its hostname matches an existing CI in the CMDB, but the serial number differs. The CI Class Manager shows that the class uses a CI Identification rule with 'Hostname' as the only identifier. What is the most likely outcome for this CI?

You are configuring a Discovery CI identification rule for Linux servers and notice that multiple CIs are being created for the same physical device. Which component should you verify to ensure the Identification Engine correctly links the incoming data to an existing CI?

During a Discovery run in a large data center, the same Windows server is being discovered by two separate MID Servers that both have network access to the server's subnet. The server appears as a single CI, but its 'Last discovered' timestamp and certain network adapter attributes keep flipping between values from each MID Server on every run. Which configuration should you review first to understand and control this behavior?
