AWS Certified SysOps Administrator – Associate (legacy) — Question 820

A user has a weighing plant. The user measures the weight of some goods every 5 minutes and sends data to AWS CloudWatch for monitoring and tracking.
Which of the below mentioned parameters is mandatory for the user to include in the request list?

Answer options

• A. Value
• B. Namespace
• C. Metric Name
• D. Time zone

Correct answer: B

Explanation

When publishing custom metrics to AWS CloudWatch using the PutMetricData API, the Namespace parameter is a mandatory top-level requirement that identifies the container for the metrics. While MetricName is required for individual metric data structures, a metric data point can use either a Value or a StatisticSet, making Value itself not strictly mandatory in all configurations. Time zone is not a valid parameter, as CloudWatch uses UTC timestamps.
