Within the CMDB class dictionary in ServiceNow, attributes can be inherited from parent classes or defined directly on a specific class. To identify attributes created specifically for the Windows Server class, administrators must use the Added tab.

The Added tab displays attributes that are unique to the selected class and not inherited from parent classes (such as Server or Computer). This is essential for understanding class-specific extensions—like Windows-only configuration details—that were introduced to support platform requirements, discovery enhancements, or organizational needs.

The All tab shows every attribute available to the class, including inherited and added attributes, which makes it difficult to isolate class-specific additions. The Child tab focuses on attributes inherited by subclasses, not attributes introduced at the current class level. The Derived tab shows attributes calculated or derived from other data, not necessarily those created specifically for the class.

Using the Added tab supports best practices for configuration transparency, impact analysis during upgrades, and governance—especially important in Data Foundations to minimize unnecessary customization and maintain upgrade-safe designs.

Therefore, the correct answer is B – Added.
