AWS Certified Machine Learning - Specialty MLS-C01 — Topic 1 Question 67

Question

A Machine Learning Specialist is developing a daily ETL workflow containing multiple ETL jobs. The workflow consists of the following processes: * Start the workflow as soon as data is uploaded to Amazon S3. * When all the datasets are available in Amazon S3, start an ETL job to join the uploaded datasets with multiple terabyte-sized datasets already stored in Amazon S3. * Store the results of joining datasets in Amazon S3. * If one of the jobs fails, send a notification to the Administrator. Which configuration will meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Use AWS Lambda to trigger an AWS Step Functions workflow to wait for dataset uploads to complete in Amazon S3. Use AWS Glue to join the datasets. Use an Amazon CloudWatch alarm to send an SNS notification to the Admin... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon S3 provides durable, scalable object storage that is fully managed. Amazon SNS is a managed pub/sub service for fan-out notifications to many subscribers.
