DOP-C02 Question 245
Select 3A DevOps team is managing an application that has dynamic traffic patterns. They want to set up alerts for CPU utilization using Amazon CloudWatch to automatically adapt to normal behavior changes over time and reduce false positives for alarms. Which of the following steps should the team take to achieve this?
- A
Enable anomaly detection for the CPU utilization metric in CloudWatch.
- B
Use a static threshold for the CPU utilization alarm to trigger alerts.
- C
Configure an anomaly detection alarm based on the CPU utilization metric.
- D
Define a specific anomaly detection model for the CPU utilization metric.
- E
Use CloudWatch Logs Insights to create queries for anomaly detection.
Show answer and explanation
Correct answers: A, C, D
Explanation
To handle dynamic traffic patterns and reduce false positives, the team should enable anomaly detection on the CPU utilization metric, define an anomaly detection model to establish a baseline for normal behavior, and configure an anomaly detection alarm. This approach allows CloudWatch to adapt to changes in the metric's behavior over time and ensures alerts are triggered only when there are significant deviations.
- A. Correct.
Correct. Enabling anomaly detection for the metric is the first step to allow CloudWatch to model the expected behavior of the metric over time.
- B. Incorrect.
Incorrect. A static threshold does not adapt to changes in normal behavior and is not suitable for dynamic traffic patterns.
- C. Correct.
Correct. Setting up an anomaly detection alarm ensures that alerts are triggered only when the metric deviates significantly from the expected behavior.
- D. Correct.
Correct. Defining an anomaly detection model allows CloudWatch to analyze the historical data and create a dynamic range for normal behavior.
- E. Incorrect.
Incorrect. CloudWatch Logs Insights is used for querying log data, not for creating anomaly detection alarms.
