Show answer and explanation
Correct answer: A
Explanation
AWS Cost Anomaly Detection is a dedicated service for identifying unusual spending patterns in your AWS account. It uses machine learning to analyze your usage and costs, and it provides detailed anomaly reports and alerts, enabling you to investigate and respond to anomalies efficiently. Other services like GuardDuty and Trusted Advisor serve different purposes and are not focused on cost anomaly detection.
- A. Correct.
Correct: AWS Cost Anomaly Detection is specifically designed to identify unexpected spending patterns in your AWS account. It provides detailed anomaly reports and allows for quick action.
- B. Incorrect.
Incorrect: Amazon GuardDuty is a threat detection service designed to identify security threats, not cost anomalies. It does not analyze AWS usage costs.
- C. Incorrect.
Incorrect: AWS Trusted Advisor offers recommendations for cost optimization but does not provide real-time anomaly detection or detailed reports for cost anomalies.
- D. Incorrect.
Incorrect: While AWS Cost Explorer is useful for analyzing historical and current AWS costs, it does not provide the dedicated anomaly detection and alerting features required to identify unexpected cost spikes effectively.
