AWS Certified SysOps Administrator – Associate — Question 456

An application team is working with a SysOps administrator to define Amazon CloudWatch alarms for an application. The application team does not know the application's expected usage or expected growth.
Which solution should the SysOps administrator recommend?

Answer options

• A. Create CloudWatch alarms that are based on anomaly detection.
• B. Create CloudWatch alarms by using a set of composite alarms.
• C. Create CloudWatch alarms by using static thresholds.
• D. Create CloudWatch alarms that treat missing data as breaching.

Correct answer: A

Explanation

Amazon CloudWatch anomaly detection uses machine learning to analyze system metrics and automatically establish a baseline of normal behavior, making it ideal when expected usage and growth are unknown. Static thresholds are not suitable here because they require predetermined limits that the team cannot yet define. Composite alarms and missing data configurations do not help establish a baseline for unknown usage patterns.
