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
✓
The payload is rejected with an error indicating an identification rule non-uniqueness.
IRE provides specific error codes to indicate when an identification rule is not unique, which must be resolved to avoid data corruption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The match is ignored, and all attributes are updated in both records.
Why it's wrong here
This would cause massive data inconsistency.
- ✗
The first match found is updated.
Why it's wrong here
IRE does not blindly update; it requires a unique match to proceed.
- ✗
A new CI is created as a duplicate.
Why it's wrong here
IRE is specifically designed to prevent duplicates.
- ✓
The payload is rejected with an error indicating an identification rule non-uniqueness.
Why this is correct
The IRE will fail the operation if an identification rule matches multiple records to maintain data integrity.
