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.
