CIS-DF Ingest Practice Question
An architect is reviewing an integration that populates network gear into the CMDB. The integration payload includes both the physical chassis and installed line cards. The implementer wants to ensure that if a line card is removed from the chassis in the physical world, its relationship in the CMDB is automatically cleaned up when the integration runs. Which feature supports this behavior?
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 the payload payload structure to mark the relationship as dependent, allowing the IRE to handle stale child relationships.
Payloads processed via IRE can use dependent relationships and payload markers to handle stale related items or orphaned child records.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the Data Source Precedence for line cards to 'Delete on Sync'.
Why it's wrong here
Data Source Precedence does not include a 'Delete on Sync' attribute configuration.
- ✓
Configure the payload payload structure to mark the relationship as dependent, allowing the IRE to handle stale child relationships.
Why this is correct
Dependent relationships in IRE payloads inform the engine when child CIs are missing from the current payload so they can be cleaned up or marked absent.
- ✗
Write a scheduled job to delete all line cards every night before the integration runs.
Why it's wrong here
Deleting and recreating records daily causes severe performance degradation, audit churn, and historical metric loss.
- ✗
Enable 'Cascade Delete' on the cmdb_rel_ci dictionary entry.
Why it's wrong here
Cascade delete on dictionary tables is a database-level feature and is not recommended or used for managing CMDB relationship lifecycles.
