What is a best practice for preventing duplicate applications in ServiceNow Discovery?

The best practice for preventing duplicate applications in ServiceNow Discovery is to configure a process handler with a CI Identifier. The CI Identifier uniquely identifies each Configuration Item (CI) within the system, enabling accurate tracking and management. By using a CI Identifier, the process handler can ensure that each discovered application is recorded only once, thereby minimizing the possibility of duplicates.

This practice is essential because duplicates can lead to inaccurate reporting, confusion among users, and potential inefficiencies in managing and utilizing the discovered data. With a proper configuration of a process handler that leverages CI Identifiers, ServiceNow Discovery can effectively differentiate between distinct applications, ensuring that each is recorded and referenced correctly in the system.

While the other options may contribute to overall system integrity or data management, they do not specifically address the prevention of duplicate applications as directly as configuring a process handler with a CI Identifier does. Centralizing database records and creating feedback loops can support the broader goals of data management but do not directly tackle the core issue of identification and recording of unique applications in the Discovery process.
