In a DI object with an Active scanning mode, what happens when the last reference to an attribute is unregistered?

• A. The attribute is retained
• B. The attribute enters a standby state
• C. The attribute is immediately deleted
• D. The attribute becomes inactive but not deleted

Answer: (C)

In a Data Integration (DI) object with an Active scanning mode, when the last reference to an attribute is unregistered, the attribute is immediately deleted. This behavior is designed to maintain efficient memory management within the application. In Active scanning mode, attributes are closely monitored and only active (or referenced) attributes are kept in memory. When the last reference to an attribute is removed, it indicates that no processes or components are currently using that attribute, prompting the system to free up resources by removing it entirely. This automatic cleanup ensures that the system does not retain unnecessary data, preventing memory bloat and optimizing performance. This concept is distinct from the other potential outcomes such as retaining the attribute, entering a standby state, or becoming inactive but not deleted. Those scenarios would imply that the attribute retains some form of presence or memory, which contradicts the logic of immediate deletion in Active scanning mode upon the last reference being unregistered.
