AWS Certified Machine Learning - Specialty MLS-C01 — Topic 1 Question 22

Question

A retail chain has been ingesting purchasing records from its network of 20,000 stores to Amazon S3 using Amazon Kinesis Data Firehose. To support training an improved machine learning model, training records will require new but simple transformations, and some attributes will be combined. The model needs to be retrained daily. Given the large number of stores and the legacy data ingestion, which change will require the LEAST amount of development effort?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Insert an Amazon Kinesis Data Analytics stream downstream of the Kinesis Data Firehose stream that transforms raw record attributes into simple transformed values using SQL. Kinesis Data Firehose delivers streaming data to destinations like S3/Redshift with no servers to manage. Amazon Kinesis ingests and processes real-time streaming data at scale.
