Exam AWS Certified Machine Learning - Specialty topic 1 question 348 discussion

Exam question from Amazon's AWS Certified Machine Learning - Specialty
Question #: 348
Topic #: 1
[All AWS Certified Machine Learning - Specialty Questions]

A company is building a predictive maintenance system using real-time data from devices on remote sites. There is no AWS Direct Connect connection or VPN connection between the sites and the company's VPC. The data needs to be ingested in real time from the devices into Amazon S3.

Transformation is needed to convert the raw data into clean .csv data to be fed into the machine learning (ML) model. The transformation needs to happen during the ingestion process. When transformation fails, the records need to be stored in a specific location in Amazon S3 for human review. The raw data before transformation also needs to be stored in Amazon S3.

How should an ML specialist architect the solution to meet these requirements with the LEAST effort?

  • A. Use Amazon Data Firehose with Amazon S3 as the destination. Configure Firehose to invoke an AWS Lambda function for data transformation. Enable source record backup on Firehose.
  • B. Use Amazon Managed Streaming for Apache Kafka. Set up workers in Amazon Elastic Container Service (Amazon ECS) to move data from Kafka brokers to Amazon S3 while transforming it. Configure workers to store raw and unsuccessfully transformed data in different S3 buckets.
  • C. Use Amazon Data Firehose with Amazon S3 as the destination. Configure Firehose to invoke an Apache Spark job in AWS Glue for data transformation. Enable source record backup and configure the error prefix.
  • D. Use Amazon Kinesis Data Streams in front of Amazon Data Firehose. Use Kinesis Data Streams with AWS Lambda to store raw data in Amazon S3. Configure Firehose to invoke a Lambda function for data transformation with Amazon S3 as the destination.

D. firehose can not store data and not real time, it is near real time firehose cant invoke glue, you can use firehose with lambda for transformation. And spark job requires more effort than lambda. Also C does not store raw data before transformation

copilot - This solution meets the requirements by: Ingesting data in real-time using Amazon Kinesis Data Firehose. Transforming the data using an AWS Lambda function during the ingestion process. Storing the transformed data in Amazon S3. Enabling source record backup to store raw data and failed transformation records in specific S3 locations. If you have any more questions or need further assistance, feel free to ask!
