Full Certification Question
A leading IT consulting firm is building a GraphQL API service and a mobile application that lets people post photos and videos of the traffic situations and other issues in the city's public roads. Users can include a text report and constructive feedback to the authorities. The department of public works shall rectify the problems based on the data gathered by the system. In order for the mobile app to run on various mobile and tablet devices, the firm decided to develop it using the React Native mobile framework, which will consume and send data to the GraphQL API. The backend service will be responsible for storing the photos and videos in an Amazon S3 bucket. The API will also need access to the Amazon DynamoDB database to store the text reports. The firm has recently deployed the mobile app prototype, however, during testing, the GraphQL API showed a lot of issues. The team decided to remove the API to proceed with the project and refactor the mobile application instead so that it will directly connect to both DynamoDB and S3 as well as handle user authentication. Which of the following options provides a cost-effective and scalable architecture for this project? (Select TWO.)
