CMDB 360 / Multisource CMDBextends the standard IRE by enablingDynamic Reconciliation Rules, which determine attribute values dynamically based on incoming data patterns rather than fixed source priority.

Within theCreate Reconciliation Rulewizard, two supporteddynamic rule typesare:

Most Reported(Option B): selects the attribute value that is reported most frequently across all sources. This is useful when multiple sources contribute data and consensus is a strong indicator of correctness.

Last Updated(Option C): selects the most recently updated value, which is useful for rapidly changing attributes such as IP address or operational state.

Option A (Smallest Value) and Option D (Last Created) are not supported dynamic reconciliation rule types in ServiceNow.

Dynamic reconciliation rules are particularly valuable in complex, multisource environments where rigid source precedence is insufficient anddata confidence must be inferred.

Therefore, the correct answers areB – Most ReportedandC – Last Updated.
