Selected Answer: B

The correct answer is: ✅ B. Allow the load to trigger adjustments to the resources. ⸻ Explanation: This approach describes auto scaling based on demand, also known as load-based or event-driven scaling, which: • Automatically adjusts resources based on real-time usage metrics (CPU, memory, requests per second, etc.) • Is cost-effective, as it scales only when necessary • Helps maintain performance and availability during traffic spikes (like during the holiday sale) • Reduces manual intervention and risk of overprovisioning
