Which action will accomplish this?
Increase the size of the RDS instance.
Create a read replica and connect the application to it.
Enable multiple Availability Zones on the RDS instance.
Create a read replica and connect the business reports to it.
Explanations:
Increasing the size of the RDS instance would not necessarily improve performance for reporting users, as the CPU and memory utilization is already under 60%.
Connecting the application to a read replica would not benefit the reporting users since it would still affect the application’s performance, which needs to be preserved.
Enabling multiple Availability Zones provides high availability and redundancy but does not directly address the performance issue for reporting users.
Creating a read replica and connecting the business reports to it allows reporting queries to be executed on the read replica, thus preventing any performance impact on the main application.
I scheme that the answer is:
Create a read replica and connect the business reports to it.
