A Company Is Building a Sensor Data Collection Pipeline in Which

question 617

Multiple Choice

A company is building a sensor data collection pipeline in which thousands of sensors write data to an Amazon Simple Queue Service (Amazon SQS) queue every minute. The queue is processed by an AWS Lambda function that extracts a standard set of metrics from the sensor data. The company wants to send the data to Amazon CloudWatch. The solution should allow for viewing individual and aggregate sensor metrics and interactively querying the sensor log data using CloudWatch Logs Insights. What is the MOST cost-effective solution that meets these requirements?

• A) Write the processed data to CloudWatch Logs in the CloudWatch embedded metric format.
• B) Write the processed data to CloudWatch Logs. Then write the data to CloudWatch by using the PutMetricData API call.
• C) Write the processed data to CloudWatch Logs in a structured format. Create a CloudWatch metric filter to parse the logs and publish the metrics to CloudWatch with dimensions to uniquely identify a sensor.
• D) Configure the CloudWatch Logs agent for AWS Lambda. Output the metrics for each sensor in statsd format with tags to uniquely identify a sensor. Write the processed data to CloudWatch Logs.
