This question tests understanding ofreconciliation source priorityin theIdentification and Reconciliation Engine (IRE)inServiceNow.

In reconciliation rules,lower numeric values represent higher priority. Therefore, the priority order is:

ServiceNow (100)– highest authority

Altiris (200)

SCCM (300)– lowest authority

Why A is correct

BecauseAltiris (200)hashigher priority than SCCM (300), data from Altiriscan update records originally inserted by SCCM. This is exactly how reconciliation precedence works—higher-priority sources can overwrite lower-priority ones.

Why C is correct

SCCM, even though it has thelowest priority, is still anauthorized discovery source. Itcan insert new recordsinto the Windows Server table when no existing CI is identified. Priority only affectsupdates, not the ability to create records.

Why B is incorrect

ServiceNow (priority 100)can update records from Altiris and SCCMbecause it has the highest priority. The statement incorrectly claims it cannot.

Why D is incorrect

SCCM doesnothave the highest authority. Ahigher numeric value means lower priority, so SCCM cannot update records created by higher-priority sources.
