Question

A company wants to build a web application on AWS. Client access requests to the website are not predictable and can be idle for a long time. Only customers who have paid a subscription fee can have the ability to sign in and use the web application. Which combination of steps will meet these requirements MOST cost-effectively? (Choose three.)

Accepted Answer

Correct answer: A, C, E. The correct answer is A, C, E. Option A: Create an AWS Lambda function to retrieve user information from Amazon DynamoDB. Create an Amazon API Gateway endpoint to accept RESTful APIs. Send the API calls to the Lambda function. Option C: Create an Amazon Cognito user pool to authenticate users. Option E: Use AWS Amplify to serve the frontend web content with HTML, CSS, and JS. Use an integrated Amazon CloudFront configuration. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. Amazon CloudFront caches content at edge locations to reduce latency and offload origins. This option delivers the requirement at the lowest cost.
