AWS Certified Data Engineer Associate DEA-C01 Practice Question

A data engineering team runs Amazon EC2-based Spark jobs in two AWS Regions. Compliance requires that application log files from /var/log/app.log on every instance be centralized in Amazon CloudWatch Logs and automatically deleted after 90 days. Which approach satisfies the requirements with minimal operational overhead?

  • Write the log files to an Amazon S3 bucket that has a lifecycle rule to expire objects after 90 days, and query the logs with Amazon Athena.

  • Configure VPC Flow Logs on the instances' subnets with 90-day retention and use CloudWatch Logs Insights to analyze the data.

  • Enable AWS CloudTrail in both Regions and set its retention to 90 days; CloudTrail will capture the application log entries automatically.

  • Create a CloudWatch Logs log group, set its retention to 90 days, and install the CloudWatch agent on each instance to monitor /var/log/app.log.
