AWS Certified Data Engineer Associate DEA-C01 Practice Question

Your company runs several Amazon EMR clusters that execute nightly Spark jobs. The engineering team wants a managed solution to aggregate application and step logs from every cluster, retain the data for 30 days, and provide near-real-time search and interactive dashboards to troubleshoot performance issues. Which approach meets these requirements with the least operational overhead?

  • Stream logs from the EMR master node to Amazon Kinesis Data Streams, invoke AWS Lambda to load the records into Amazon DynamoDB, and build Amazon QuickSight analyses on the table.

  • Install Filebeat on every EMR node to forward logs to an ELK stack running on a separate always-on EMR cluster and delete indices older than 30 days.

  • Enable log archiving to Amazon S3, run Amazon Athena queries against the logs, and visualize the results in Amazon QuickSight with a 30-day lifecycle policy on the S3 bucket.

  • Configure each EMR cluster to publish its logs to CloudWatch Logs, create a CloudWatch Logs subscription that streams the logs to an Amazon OpenSearch Service domain, and set a 30-day retention policy on the log groups.
