Question 15: Orphan CI
In the context of the CMDB, what does an “Orphan CI” refer to?
- A. A CI with an unknown owner.
- B. A CI that has no relationships with any other CI.
- C. A CI that has not been updated for more than one year.
- D. A CI that is powered off.
【Correct Answer】 B. A CI that has no relationships with any other CI.
【Detailed Explanation】
Why B is the correct answer (Definition of an Orphan CI):
An “Orphan” in the CMDB literally refers to data that has lost its connection to a “parent” or “child.”
- Lack of Dependencies: In the ServiceNow CMDB, it is assumed that CIs are connected by relationships such as “Runs on” or “Depends on.”
- Judgment Criteria: If a CI violates the rule defined in the CI Class Manager stating that “CIs of this class should have at least one parent (or child)” and remains an independent record not connected to any other CI, it is counted as an “Orphan CI.”
Why the other options are incorrect:
- A (Unknown Owner): This is a “missing attribute” issue and is checked under the Completeness metric of CMDB Health.
- C (Not updated for over a year): This is called a Stale CI and is a different sub-metric within the Correctness metric.
- D (Powered off): This is a matter of the CI’s “Operational Status” and is not directly related to data integrity or health.
This concludes the practice questions.
