AWS Certified Data Engineer – Associate (DEA-C01) — Question 118

A data engineer uses Amazon Managed Workflows for Apache Airflow (Amazon MWAA) to run data pipelines in an AWS account.

A workflow recently failed to run. The data engineer needs to use Apache Airflow logs to diagnose the failure of the workflow.

Which log type should the data engineer use to diagnose the cause of the failure?

Answer options

• A. YourEnvironmentName-WebServer
• B. YourEnvironmentName-Scheduler
• C. YourEnvironmentName-DAGProcessing
• D. YourEnvironmentName-Task

Correct answer: D

Explanation

The correct answer is D, as the YourEnvironmentName-Task logs contain detailed information about the execution of tasks within the workflow, which is crucial for diagnosing failures. The other log types, while useful, do not provide specific insights into task execution issues that led to the failure.
