Question
A company is running a multi-tier web application on AWS. The application runs its database tier on Amazon Aurora MySQL. The application and database tiers are in the us-east-1 Region. A database administrator who monitors the Aurora DB cluster finds that an intermittent increase in read traffic is creating high CPU utilization on the read replica. The result is increased read latency for the application. The memory and disk utilization of the DB instance are stable throughout the event of increased latency. What should a solutions architect do to improve the read scalability?
Options
- AReboot the DB cluster.
- BCreate a cross-Region read replica.
- CConfigure Aurora Auto Scaling for the read replica.
- DIncrease the provisioned read IOPS for the DB instance.

Explanation
Aurora Auto Scaling allows read replicas to automatically scale in and out based on changes in read traffic. By enabling Auto Scaling for the read replica, the solution accommodates intermittent spikes in read requests, reducing CPU utilization and read latency without manual intervention.
