A company wants to set up Amazon Managed Grafana as its visualization tool and visualize data from an Amazon RDS database as a single data source. The solution must be secure and must not expose the data over the internet. Which solution meets these requirements?

The correct solution involves creating an Amazon Managed Grafana workspace within a Virtual Private Cloud (VPC) and configuring the Amazon RDS database with a private endpoint. This ensures that the data communication between Grafana and RDS remains entirely within the AWS private network, satisfying the security requirement of not exposing data over the internet. Using a private endpoint for RDS prevents public access, and placing Grafana in a VPC allows it to access private resources within that VPC. Incorrect options: Creating a public endpoint for RDS exposes the database to the internet, violating the security requirement. Using AWS PrivateLink for a connection between Amazon Managed Grafana and Amazon RDS is not the standard or most direct method when both are within a VPC and private access is desired. PrivateLink is typically used for exposing services to other VPCs or on-premises networks securely. Placing Grafana in a VPC but using a public RDS endpoint still exposes the database to the internet.
