SCS-C02 Question 495
Select 2Your organization has noticed an unexpected spike in AWS costs for the current month. As a Security Engineer, you need to identify and investigate potential anomalies in the usage and cost patterns. Which of the following actions should you take to detect and understand the irregularities in AWS usage? (Select TWO)
- A
Enable AWS Cost Anomaly Detection and create anomaly detection monitors for relevant services.
- B
Review the Cost Explorer and apply filters such as service, region, and linked accounts to identify anomalies.
- C
Disable all IAM users temporarily to prevent unauthorized access to AWS resources.
- D
Enable AWS Trusted Advisor to receive recommendations for unused or underutilized resources.
- E
Set up an AWS Config rule to monitor changes to EC2 instance types and sizes.
Show answer and explanation
Correct answers: A, B
Explanation
To identify and investigate cost anomalies, you should use tools like AWS Cost Anomaly Detection and AWS Cost Explorer. These services provide insights into cost and usage trends and help you pinpoint irregularities. While other options like Trusted Advisor and AWS Config are useful for optimization and compliance, they do not directly address the need for anomaly detection in costs.
- A. Correct.
Correct. AWS Cost Anomaly Detection is specifically designed to monitor and detect unusual spending patterns in AWS services, making it a key tool in identifying anomalies.
- B. Correct.
Correct. AWS Cost Explorer provides detailed insight into service-specific costs, which allows you to analyze trends and pinpoint unusual increases in usage or costs.
- C. Incorrect.
Incorrect. Disabling all IAM users is not a recommended practice for investigating cost anomalies and could disrupt legitimate operations.
- D. Incorrect.
Incorrect. AWS Trusted Advisor provides optimization recommendations, but it is not primarily used for detecting cost anomalies or analyzing unexpected cost spikes.
- E. Incorrect.
Incorrect. AWS Config monitors resource configuration changes but does not directly help in identifying cost anomalies or usage spikes.
