AWS Certified Data Engineer Associate DEA-C01 Practice Question

An EMR cluster writes detailed Spark application logs to an S3 bucket. Engineers must perform ad-hoc, interactive troubleshooting by filtering on executor IDs and calculating average task duration. They want a solution that requires no clusters to manage and keeps costs low, paying only for queries run. Which approach meets these requirements?

  • Spin up a temporary EMR cluster with Hive, copy the logs to HDFS, and issue Hive queries.

  • Stream the logs to CloudWatch Logs and analyze them with CloudWatch Logs Insights.

  • Ingest the logs with Logstash into an Amazon OpenSearch Service domain and query them in Kibana.

  • Create an Amazon Athena external table that points to the S3 log prefix and run SQL queries against it.
