Which solution should the SysOps administrator recommend?
Create CloudWatch alarms that are based on anomaly detection.
Create CloudWatch alarms by using a set of composite alarms.
Create CloudWatch alarms by using static thresholds.
Create CloudWatch alarms that treat missing data as breaching.
Explanations:
Anomaly detection automatically adapts to changes in usage patterns, making it ideal for situations where expected usage and growth are unknown.
Composite alarms are used to combine multiple alarms into one, which does not address the uncertainty in expected usage or growth effectively.
Static thresholds are fixed values and would require the application team to have knowledge of expected usage and growth, which they currently do not have.
Treating missing data as breaching could lead to false alarms or missed alerts when data is temporarily unavailable, which is not ideal in this situation.
I assess that the answer is:
Create CloudWatch alarms that are based on anomaly detection.
