What can lead to the creation of duplicate records during identification?

The creation of duplicate records during the identification process in ServiceNow Discovery can often stem from incorrectly defined reconciliation definitions. Reconciliation definitions are essential because they govern how configuration items (CIs) are evaluated and merged within the platform. If these definitions are not set up correctly, they might fail to recognize that certain CIs are actually the same or represent the same entity in the environment. This oversight can result in the same CI being recorded multiple times, as the system does not properly identify them as duplicates.

In the context of the other choices, while lack of network connectivity may prevent accurate data collection, it does not specifically lead to the systemic creation of duplicates. Insufficient data sources may limit the information available for discovery but does not inherently cause duplicates. Additionally, incorrect CI identifiers could result in some confusion during discovery; however, they would typically affect how CIs are recognized rather than directly causing duplicate records under normal circumstances. Overall, the mechanism of reconciliation definitions is a critical factor in preventing duplicate entries in the system.
