Question #1411
A healthcare provider has launched a new analytics platform to process patient data in real-time. The provider is unable to forecast the volume of data processing required during peak periods, leading to concerns about system responsiveness. Which AWS Cloud computing benefit addresses this challenge?
Easy to use
Cost-effective
Secure
Scalable and high performance
Explanation
The healthcare provider's challenge revolves around handling unpredictable data processing volumes during peak periods. AWS's scalability (a core cloud computing benefit) enables automatic resource provisioning (e.g., using Auto Scaling, Amazon Kinesis, or Lambda) to meet fluctuating demands, ensuring consistent performance.
- Why D is correct: Scalability allows the system to dynamically scale up/down based on workload, eliminating the need for manual forecasting. High-performance AWS services (e.g., EC2, DynamoDB) maintain responsiveness even under heavy loads.
- Why others are incorrect:
- A (Easy to use): Ease of use doesn't resolve capacity planning issues.
- B (Cost-effective): While AWS offers pay-as-you-go pricing, cost savings aren't the primary concern here.
- C (Secure): Security is critical for healthcare data but doesn't address scaling challenges.
Key Takeaway: AWS scalability ensures systems adapt to variable workloads, making it ideal for real-time analytics with unpredictable peaks.
Answer
The correct answer is: D
