Question
An application uses an Amazon Aurora MySQL DB cluster that includes one Aurora Replica. The application's read performance degrades when there are more than 200 user connections.

A SysOps administrator must implement a solution that will scale the application automatically as user demand increases or decreases. Which solution will meet these requirements?
Options
- AModify the DB cluster by increasing the Aurora Replica instance size.
- BModify the DB cluster by changing to serverless mode whenever the number of user connections
- CMigrate to a new Aurora DB cluster that has multiple writer instances. Modify the application's
