A smart building system collects temperature, occupancy, and energy usage data. The facility manager needs a daily summary report and also wants to detect unusual patterns immediately. Which cloud processing approach should be used?

Use only batch processing for both daily reports and anomaly detection

Use only stream processing for both daily reports and anomaly detection

Store all data in a data lake and run ad-hoc queries for everything

Use stream processing for real-time anomaly detection and batch processing for daily reports

A ride-sharing company's IoT devices send location updates every 5 seconds. The system experiences predictable spikes during rush hours. The company wants to ensure that the cloud infrastructure can handle the spikes without performance degradation, while keeping costs low during off-peak hours. Which approach is most effective?

Use a single large instance to handle all traffic

Use reactive auto-scaling based on CPU utilization only

Provision a fixed number of instances that can handle the peak load at all times

Use auto-scaling with a scheduled scaling policy that aligns with rush-hour patterns
