QuestionQ41

Monitoring, Logging, Analysis, Remediation, and Performance Optimization

A company’s reporting job, which previously completed in 15 minutes, now takes an hour. An application produces the reports. The application runs on Amazon EC2 instances and retrieves data from an Amazon RDS for MySQL database.

A CloudOps engineer reviews the Amazon CloudWatch dashboard for the RDS instance and observes high Read IOPS metrics, even when the reports are not running. The CloudOps engineer must improve the RDS instance’s performance and availability.

Which solution meets these requirements?

Explanation
