Question 66:
You have created a mobile application that serves data stored in an Amazon DynamoDB table. Your primary concern is scalability of the application and ability to handle millions of visitors and data requests. As part of your application, the customer needs access to the data located in the DynamoDB table. Given the application requirements, what would be the best method to design the application? Choose the correct answer from the options below.
Answer options:
A.Configure an on-premise AD server utilizing SAML 2.0 to manage the application users inside the on-premise AD server and write code that authenticates against the LD serves. Grant a role assigned to the STS token to allow the end-user to access the required data in the DynamoDB table. B.Let the users sign into the app using a third-party identity provider such as Amazon, Google, or Facebook. Use the AssumeRoleWith API call to assume the role containing the proper permissions to communicate with the DynamoDB table. Write the application in JavaScript and host the static webpage in an S3 bucket. C.Let the users sign into the app using a third-party identity provider such as Amazon, Google, or Facebook. Use the AssumeRoleWithWebIdentity API call to assume the role containing the proper permissions to communicate with the DynamoDB table. Write the application in a server-side language using the AWS SDK and host the application in an S3 bucket for scalability. D.Let the users sign in to the app using a third-party identity provider such as Amazon, Google, or Facebook. Use the AssumeRoleWithWebIdentity API call to assume the role containing the proper permissions to communicate with the DynamoDB table. Write the application in JavaScript and host the static webpage in an S3 bucket.
