CIS-DF Ingest Practice Question
An administrator is troubleshooting an integration where an incoming JSON payload contains relationships between servers and IP addresses. The server is created successfully, but the relationship record in `cmdb_rel_ci` is missing. Upon checking the IRE execution log, the system indicates that the relationship type string was invalid. How should this be resolved?
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.

✓
Ensure the relationship type specified in the payload matches an active parent/child relationship name defined in the `cmdb_rel_type` table.
Relationship types specified in payloads must match active record values in the `cmdb_rel_type` table.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable relationship validation in CMDB properties.
Why it's wrong here
Disabling relationship validation is not supported and compromises CMDB relationship integrity.
- ✓
Ensure the relationship type specified in the payload matches an active parent/child relationship name defined in the `cmdb_rel_type` table.
Why this is correct
The IRE validates relationship type strings against the cmdb_rel_type table; invalid or misspelled relationship types cause relationship creation to fail.
- ✗
Create a Transform Map to map relationship types.
Why it's wrong here
Transform maps are for import staging tables, not direct IRE relationship payload validation.
- ✗
Modify the cmdb_rel_ci table dictionary to allow free-text relationship types.
Why it's wrong here
Relationship types are governed by reference records in cmdb_rel_type, not free-text dictionary fields.
