Upon reviewing CI class manager settings, which feature or setting most likely caused this behavior due to incorrect payload identification?
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
✓
Identification and Reconciliation Engine (IRE) identification rules and dependent relationship definitions
IRE (Identification and Reconciliation Engine) rules and identification rules govern how payloads update CIs and relationships. Incorrect payload definitions or stale relationship rules can cause relationships to be pruned or ignored.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data Dictionary cascade delete settings on the sys_dictionary table
Why it's wrong here
Cascade delete on sys_dictionary would delete table structures, not individual CI relationships.
- ✗
CMDB Health dashboard completeness scorecards
Why it's wrong here
The CMDB Health dashboard is a reporting tool and does not actively modify or delete relationships during discovery runs.
- ✓
Identification and Reconciliation Engine (IRE) identification rules and dependent relationship definitions
Why this is correct
IRE uses identification rules and relationship rules to process payloads; misconfigured rules can cause payloads to drop or overwrite relationship data.
- ✗
Discovery Schedule exclude rules
Why it's wrong here
Exclude rules prevent scanning entirely, they do not prune existing relationships.
