A tool in Real-Time Intelligence in Fabric that can be used to trigger actions on streaming data. For example, a weather sensor might trigger emails when wind thresholds are met.

• A. Stream Trigger
• B. Activator
• C. Stream Emailer
• D. EventRouter

Answer: (B)

The key idea is triggering automated actions based on real-time data. In Real-Time Intelligence, the Activator serves as the event-driven component that watches streaming data and fires downstream actions when a defined condition is met, such as a weather wind speed threshold being reached. This is exactly what you want when you need something to happen automatically—like sending an email alert—once the live data crosses the specified limit.

Other options don’t fit as well. A Stream Trigger describes starting a process when new data arrives but doesn’t inherently specify taking an action like sending an email based on a rule. An EventRouter would route events to destinations but isn’t the mechanism that initiates the action itself. The Stream Emailer isn’t a standard component for this workflow.
