AWS Certified Solutions Architect Associate SAA-C03 Practice Question

A data engineering team stores hundreds of gigabytes of raw CSV files in an Amazon S3 data lake. They need to convert this data to Apache Parquet on a daily schedule as part of an ETL pipeline. The team wants a fully managed, serverless solution that lets them define the pipeline visually and perform the conversion without writing any code. Which AWS service or feature best meets these requirements?

  • Launch an Amazon EMR cluster running a custom Spark script that converts the files.

  • Configure Amazon S3 event notifications to trigger an AWS Lambda function that runs a Python conversion script.

  • Create an AWS Glue Studio visual ETL job that reads the CSV files and writes the output in Parquet format.

  • Set up AWS Data Pipeline with a ShellCommandActivity that uses the parquet-mr tool to rewrite the files.
