   A factory uses IoT sensors on robotic arms to monitor temperature and vibration. The maintenance team wants to predict equipment failures before they occur to reduce downtime. The data is streamed continuously, and the team has historical failure data. Which analytics approach is most effective?

   • AStore all data in a data lake and run batch analytics weekly
   • BTrain a machine learning model on historical data and apply it in real time to the streaming sensor data
   • CUse simple threshold-based alerts on the streaming data
   • DUse a dashboard to visualize the streaming data for manual monitoring

   An agricultural company uses soil moisture sensors in fields. The sensors transmit data every 10 minutes to a central server. The company needs to monitor soil conditions in near real time to optimize irrigation, but the fields have limited internet connectivity. Which approach is most appropriate?

   • AUse a data lake to store all raw data and process it later
   • BUse edge computing at the field gateway to process data locally and send only alerts or summaries to the central server
   • CUse batch processing at the central server to analyze data daily
   • DUse stream processing at the central server to analyze all data in real time
