AWS Certified Data Engineer Associate DEA-C01 Practice Question

An AWS Step Functions workflow processes daily sales files. When any task fails after exhausting its retries, the data engineering team must raise an alert that (1) persists for at least 4 days, (2) can be fetched every minute by a polling script, and (3) is never delivered more than once per failure. Which solution meets these requirements most cost-effectively?

  • Write the failure to Amazon CloudWatch Logs; use a metric filter and alarm to send a notification to an SNS standard topic that the script consumes.

  • Emit the failure as a custom event to Amazon EventBridge; configure the monitoring script to pull events via an API destination every minute.

  • Add a Catch path that publishes to an Amazon SNS standard topic; subscribe the monitoring script through an HTTPS endpoint.

  • Add a Catch path that publishes a JSON payload to an Amazon SQS FIFO queue configured with a 5-day retention period; have the monitoring script poll the queue for messages.
