AWS Certified SysOps Administrator – Associate (legacy) — Question 801

A user is collecting 1000 records per second. The user wants to send the data to CloudWatch using a custom namespace. Which of the below mentioned options is recommended for this activi-ty?

Answer options

• A. Create one csv file of all the data and send a single file to CloudWatch
• B. Aggregate the data with statistics, such as Min, max, Average, Sum and Sample data and send the data to CloudWatch
• C. It is not possible to send all the data in one call. Thus, it should be sent one by one. CloudWatch will aggregate the data automatically
• D. Send all the data values to CloudWatch in a single command by separating them with a comma. CloudWatch will parse automatically

Correct answer: B

Explanation

Publishing 1,000 individual metric data points per second to CloudWatch would quickly exceed API throttle limits and incur high costs. The recommended best practice is to pre-aggregate high-frequency data locally into a StatisticSet (containing Min, Max, Sum, and SampleCount) before calling the PutMetricData API. CloudWatch does not support direct CSV uploads or automatic comma-separated parsing for raw data ingestion.
