AWS Certified Developer Associate DVA-C02 Practice Question

A developer needs to programmatically publish a single data point for a custom metric to Amazon CloudWatch from an AWS Lambda function. The metric, named 'ImagesProcessed', will be in a custom namespace. What is the most direct method to publish this metric from within the Lambda function's code?

  • Write the metric as a structured JSON log message to standard output so that a CloudWatch Logs metric filter can extract it.

  • Store the metric count in an Amazon DynamoDB table and then have CloudWatch read the metric from the table.

  • Send the metric data to an Amazon SQS queue for a separate monitoring service to process and forward to CloudWatch.

  • Call the putMetricData operation using the CloudWatch client, providing the metric namespace, name, and value.
