A web-based application is running in AWS. The application is using a MySQL Amazon RDS database instance for persistence. The application stores transactional data and is read-heavy. The RDS instance gets busy during the peak usage, which shows the overall application response times.
The SysOps Administrator is asked to improve the read queries performance using a scalable solution.
Which options will meet these requirements? (Choose two.)

A. Scale up the RDS instance to a larger instance size
B. Enable the RDS database Multi-AZ option
C. Create a read replica of the RDS instance
D. Use Amazon DynamoDB instead of RDS
E. Use Amazon ElastiCache to cache read queries
