Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Discovery Schedule Exclude filters
Why it's wrong here
Exclude filters prevent scanning entire IP ranges, not specific attribute updates.
- ✗
Access Control Lists (ACLs)
Why it's wrong here
ACLs block users based on roles; they cannot differentiate between automated integration sources updating the same record.
- ✓
Reconciliation Definition (Data Precedence)
Why this is correct
Data precedence rules determine which discovery sources or data integration jobs have write priority for specific attributes.
- ✗
Business Rules on the cmdb_ci table
Why it's wrong here
Writing business rules to block discovery updates circumvents the IRE and is not a recommended data precedence practice.
