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

• A. The attribute gets deleted immediately
• B. The attribute goes inactive but is not deleted
• C. The system crashes
• D. All associated attributes are deleted

Answer: (B)

In a DI object with ActiveAll scanning mode, when the last reference to an attribute is unregistered, the attribute goes inactive but is not deleted. This behavior is intentional to allow for resource management and stability within the application. When attributes are set to inactive, they still retain their configuration and data in memory, but they will not be actively updated or monitored until there is a new reference registered. This allows the system to manage resources efficiently, as active attributes can consume more resources. By ensuring that attributes remain in a non-deleted state, the system can quickly reactivate them when a new reference is registered without the overhead of reinitializing or recreating the attribute. This behavior helps maintain consistent object states and allows for smoother transitions between active and inactive states, supporting better performance in applications where attributes may not always be needed actively.
