A data platform team uses an Amazon EMR cluster to run daily data processing jobs. They want to be notified immediately if the cluster's CPU utilization exceeds 80% for more than 10 minutes, so they can investigate potential performance issues. What should they do?

Use CloudWatch Logs Insights to query the EMR cluster's logs and set up a metric filter that triggers an SNS notification.

Enable CloudTrail for the EMR cluster and configure an SNS notification for any API calls that modify the cluster.

Create a CloudWatch alarm on the EMR cluster's CPUUtilization metric and set an SNS topic as the alarm action.

Create an SNS topic and subscribe the team's email addresses, then publish a message to the topic every time the CPU exceeds 80%.

A data engineer is troubleshooting a slow data pipeline and wants to review the application logs generated by the pipeline. Which AWS service should be used to query these logs?

Amazon CloudWatch Logs Insights

A company runs a custom Python application on an EC2 instance that processes data from an SQS queue. The application writes structured logs to a local file. The data engineering team wants to centralize these logs in CloudWatch Logs and be able to search for specific error messages. What should they do?

Use the AWS CLI to manually upload the log file to CloudWatch Logs after the application finishes processing.

Enable CloudTrail for the EC2 instance and configure it to capture application logs.

Install the CloudWatch Logs agent on the EC2 instance and configure it to stream the log file to a CloudWatch Logs log group.

Configure the application to send logs directly to an S3 bucket and use Athena to query them.
