CIS-DF Practice Question: An organization implements CSDM and wants to ingest business applications and their…
An organization implements CSDM and wants to ingest business applications and their hosting environments. They receive a payload containing a Business Application CI that references a non-existent Application Service CI. How does the IRE handle references to related CIs that do not yet exist in the CMDB?
⚠ Common exam trap
CIS-DF often tests the IRE's handling of missing references: candidates may think the IRE always creates placeholders or aborts, but it actually creates missing CIs only if nested identification blocks are provided.

Correct answer & explanation
✓
If the payload includes nested identification blocks for the related CI, the IRE will create the missing CI first and then establish the relationship.
The IRE can handle references to non-existent CIs if the payload includes nested identification blocks for those related CIs. In that case, the IRE will create the missing CI first (using the nested identification block) and then establish the relationship. This allows for the ingestion of complex CI hierarchies in a single payload.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
References to non-existent CIs are automatically converted into Incident records in IT Service Management.
Why it's wrong here
The Identification and Reconciliation Engine (IRE) only identifies, creates, updates and reconciles configuration items and their relationships in the CMDB. It never creates incident records, which belong to IT Service Management and are raised when a service is disrupted. An unresolved reference during ingestion is a data problem, reported in the IRE's output and logs for the data source, not a service outage requiring an incident.
- ✗
The IRE automatically creates dummy placeholder records for any unresolving reference.
Why it's wrong here
Creating placeholder records with no real identifying data would add junk configuration items that cannot be matched or reconciled later, harming CMDB integrity. The IRE relies on identification rules: a related CI is created only when the payload supplies enough identifying information for it. If it does not, the relationship cannot be built, and the problem is reported for the data source to correct.
- ✗
The entire payload is always aborted if any single related reference cannot be resolved immediately.
Why it's wrong here
The IRE processes the items in a payload individually and reports a result for each, so one unresolvable reference does not have to discard the whole payload; the Business Application can still be created or updated while the relationship error is reported. Strictly atomic, all-or-nothing behaviour is not how CMDB ingestion is designed, because partial, well-reported success is more useful than losing every item in a large batch.
- ✓
If the payload includes nested identification blocks for the related CI, the IRE will create the missing CI first and then establish the relationship.
Why this is correct
When the payload includes the related Application Service as its own item with identifying attributes, the IRE can resolve it, creating it if it does not exist, and then create the relationship to the Business Application. This dependency handling lets one payload describe both CIs and their relationship. Without identifying data for the related CI, the IRE has nothing to match or create, and the relationship is reported as unresolved.
