Question 525

Accompany is building an application to collect and transmit sensor data from a factory. The application will use AWS IoT Core to send data from hundreds of devices to an Amazon S3 data lake. The company must enrich the data before loading the data into Amazon S3.

The application will transmit the sensor data every 5 seconds. New sensor data must be available in Amazon S3 less than 30 minutes after the application collects the data. No other applications are processing the sensor data from AWS IoT Core.

Which solution will meet these requirements MOST cost-effectively?

    Correct Answer: A

    The most cost-effective solution involves the minimum necessary services that can achieve the requirements. By creating a topic in AWS IoT Core to ingest the sensor data, you leverage a robust platform designed to handle incoming IoT data. Using an AWS Lambda function to enrich and write the data to Amazon S3 is both straightforward and efficient. Configuring an AWS IoT rule action to invoke the Lambda function ensures that the data is processed and stored in S3 within the required timeframe, without the need for additional services like Kinesis, which would increase the complexity and cost of the solution.

Discussion
HelpnosenseOption: A

Vote A because only required minimum services are involved. IoT core topic to hold income data, Lambda to enrich data and save to s3. IoT rule call Lambda and consume the incoming data.

053081fOption: A

In this application, sensor data is transmitted at the following intervals: 1. Device to IoT Core (every 5 seconds) 2. IoT Core to S3 (every 30 minutes) The data load from IoT Core to S3 doesn't necessarily need to be real-time, and the most cost-effective solution is option A. Option A uses the simplest method to load data without using resources like Kinesis.

A Simple and most cost-effective.

vip2Option: B

B is correct

WuhaoOption: D

D is a typical scenario
