A solutions architect is designing a REST API in Amazon API Gateway for a cash-payback service. The application requires 1 GB of memory and 2 GB of storage for its computation, and it needs relational data storage. Which combination of AWS services will meet these requirements with the LEAST administrative effort? (Choose two.)

AWS Lambda is a serverless compute service that automatically scales and requires minimal administrative effort. It can be configured with up to 10 GB of memory, easily accommodating the 1 GB requirement. While it doesn't directly provide persistent storage, it integrates well with other AWS services for data. Amazon RDS is a managed relational database service that supports various database engines and handles patching, backups, and scaling, significantly reducing administrative overhead for relational data storage. Amazon EC2 would require managing servers, operating systems, and scaling, increasing administrative effort. Amazon DynamoDB is a NoSQL database, not suitable for relational data. Amazon EKS is a managed Kubernetes service for container orchestration, which is more complex and requires more administrative effort than Lambda for a single API endpoint.
