Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure Reconciliation Definitions with attribute-level precedence rules.
Reconciliation definitions allow administrators to set attribute-level precedence, ensuring authoritative sources can protect specific fields from being overwritten by secondary discovery sources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a Business Rule on the cmdb_ci table to check the updated-by user.
Why it's wrong here
Custom Business Rules on cmdb tables impact performance and bypass native IRE reconciliation features.
- ✗
Modify the Identification Rule to exclude the manual attributes.
Why it's wrong here
Identification rules dictate how records are matched, not which attributes are allowed to be updated once matched.
- ✓
Configure Reconciliation Definitions with attribute-level precedence rules.
Why this is correct
Reconciliation definitions specify which discovery sources have authority to update designated attributes.
- ✗
Disable the data source integration entirely.
Why it's wrong here
Disabling the integration loses all other valuable telemetry gathered by the data source.
