DAS-C01 Question #173: Real Exam Question with Answer & Explanation

Question

A company has multiple data workflows to ingest data from its operational databases into its data lake on Amazon S3. The workflows use AWS Glue and Amazon EMR for data processing and ETL. The company wants to enhance its architecture to provide automated orchestration and minimize manual intervention. Which solution should the company use to manage the data workflows to meet these requirements?

Options

• AAWS Glue workflows
• BAWS Step Functions
• CAWS Lambda
• DAWS Batch

Explanation

{"question_number": 1, "correct_answer": "B", "explanation": "AWS Step Functions is the correct choice for orchestrating multi-service data workflows. It is a fully managed serverless orchestration service that can coordinate AWS Glue ETL jobs, Amazon EMR clusters, Lambda functions, and other AWS services into visual, automated state machine workflows. It supports error handling, retries, conditional branching, and parallel execution - all minimizing manual intervention. AWS Glue Workflows (A) are limited to Glue-specific jobs and cannot natively orchestrate EMR. Lambda (C) is a compute service, not an orchestration engine. AWS Batch (D) is designed for batch compute jobs and does not provide the broad multi-service orchestration needed here.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
