Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
A data team already maintains complex Airflow DAGs with custom sensors and wants a managed AWS service with minimal DAG rewrites. Which orchestration service should the team use?
- Amazon Managed Workflows for Apache Airflow.
- S3 Lifecycle rules.
- AWS Step Functions Express Workflows only.
- DynamoDB Streams alone.
Amazon Managed Workflows for Apache Airflow. — MWAA is the managed AWS option for teams that need Airflow-compatible DAG authoring and scheduling.
S3 Lifecycle rules. — Lifecycle transitions or expires objects but does not coordinate DAG tasks.
AWS Step Functions Express Workflows only. — Step Functions can orchestrate serverless tasks, but it does not directly preserve Airflow DAGs.
DynamoDB Streams alone. — Streams can trigger processing but do not replace Airflow DAG orchestration.
