AWS Certified SysOps Administrator – Associate (legacy) — Question 188

A user has setup a custom application which generates a number in decimals. The user wants to track that number and setup the alarm whenever the number is above a certain limit. The application is sending the data to CloudWatch at regular intervals for this purpose. Which of the below mentioned statements is not true with respect to the above scenario?

Answer options

• A. The user can get the aggregate data of the numbers generated over a minute and send it to CloudWatch
• B. The user has to supply the time zone with each data point
• C. CloudWatch will not truncate the number until it has an exponent larger than 126 (i.e. (1 x 10^126))
• D. The user can create a file in the JSON format with the metric name and value and supply it to CloudWatch

Correct answer: B

Explanation

Option B is incorrect because CloudWatch does not require the user to specify the time zone for each data point; it operates in UTC time. The other options are accurate as they describe valid functionalities and limitations of CloudWatch regarding data aggregation, truncation, and data submission formats.
