Which statement about event registry reliability is supported by the material?

• A. An event must be registered to function
• B. Events function without registration
• C. Registration is optional
• D. Events are deprecated

Answer: (A)

Event handling relies on the Event Registry to know which events exist and what actions to take when they occur. When an event is registered, it gets a defined name in the registry and is linked to the code, workflows, or notifications that should run in response. This wiring makes behavior predictable and reliable because there’s a clear path from the event firing to its handling logic. If an event isn’t registered, the registry has nothing to match against, so the event won’t trigger any handlers and the expected response won’t happen. Therefore, an event must be registered to function. Unregistered events won’t trigger, registration isn’t optional, and there’s no indication that events are deprecated.
