顧客は、最近インポートされたサーバー レコードが ServiceNow Discovery によって検出された後、より具体的な CMDB クラスに自動的に再分類されることを希望しています。
検出プロセス中に、既存のサーバー レコードが Linux サーバー クラスと Windows サーバー クラスに再分類される場合、どの再分類操作が発生しますか?
正解：C
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.
