What is the default CI identifier used for child classes in the Hardware class?

The default CI identifier used for child classes in the Hardware class is known as the Default CI Identifier for Hardware. This is because, in ServiceNow’s Configuration Management Database (CMDB), the hierarchy and structure of Configuration Items (CIs) are designed for clarity and uniformity. The Default CI Identifier serves as a fundamental reference point for any child class that is derived from the Hardware class, ensuring that all hardware assets are consistently categorized and can be easily identified within the system.

This approach helps maintain organizational standards while also simplifying the management and retrieval of CIs. By providing a specific identifier for the Hardware class, ServiceNow enables better tracking and auditing of all related hardware items, which is essential for maintaining an accurate inventory and managing IT assets effectively.
