ServiceNow CIS-DF Exam - Topic 1 Question 15 Discussion
Topic #: 1
A customer wants recently imported server records to be automatically reclassified into more specific CMDB classes after being discovered by ServiceNow Discovery.
During the discovery process, if existing Server records are reclassified into the Linux Server and Windows Server classes, which reclassification operation occurs?
In the CMDB class hierarchy, Server is a generic parent class, while Linux Server and Windows Server are more specific child classes. When ServiceNow Discovery detects sufficient evidence (such as OS signatures) to move a CI from a generic class to a more specialized one, this action is called a Class Upgrade.
A Class Upgrade occurs when a CI is reclassified down the hierarchy into a more specific subclass, enriching the record with additional attributes, behaviors, and discovery patterns appropriate to that class. This is a standard and expected behavior in mature CMDB implementations and aligns with Data Foundations best practices.
A Class Switch would imply lateral movement between unrelated classes, which is not what happens here. A Class Downgrade would move a CI from a specific class back to a more generic one, typically when discovery confidence is reduced---not the case in this scenario.
By performing class upgrades automatically, Discovery improves CMDB accuracy, reporting precision, and service mapping quality without manual intervention.
Therefore, the correct answer is C -- Class Upgrade.
