Sample Questions

Question #517 / 529

A company is developing a mobile backend using AWS. The backend uses Amazon API Gateway REST API to trigger an AWS Lambda function, which processes data and stores it in an Amazon DynamoDB table. The company wants to implement user authentication, leveraging their existing third-party identity provider that issues OAuth 2.0 tokens. They need a solution that integrates seamlessly with their current setup.

Which solution meets these requirements?

A

Integrate the third-party identity provider with API Gateway. Configure an API Gateway Lambda authorizer to validate OAuth 2.0 tokens from the identity provider. Enforce the Lambda authorizer on all API endpoints. Update the mobile backend to obtain tokens from the identity provider and include them in the Authorization header for API Gateway requests.

B

Integrate the third-party identity provider with Amazon Cognito. Configure Cognito as a JWT authorizer for API Gateway to validate tokens. Enforce the Cognito authorizer on all API endpoints. Update the mobile backend to use Cognito-hosted UI for token retrieval and include tokens in API requests.

C

Integrate the third-party identity provider with AWS IAM. Configure IAM roles with permissions to invoke the API Gateway REST API. Update the mobile backend to assume the IAM role using AWS Security Token Service (STS) and sign requests with SigV4 signatures.

D

Integrate the third-party identity provider with AWS IAM Identity Center. Configure API Gateway to use IAM Identity Center for automatic token validation. Update the mobile backend to retrieve temporary credentials from IAM Identity Center and include them in API requests.

Question #318 / 529

Sample Questions

Question #177 / 557

A video streaming platform is expanding compatibility to support thousands of devices with varying screen resolutions. Thumbnail images for videos are stored in Amazon S3 in their original resolution. The platform uses Amazon CloudFront to serve these thumbnails. The app includes the device's resolution as a GET parameter in each request.

A developer needs to implement a solution that optimizes thumbnails for each device's resolution to improve load times and visual quality while minimizing costs.

Which solution MOST cost-effectively meets these requirements?

A

Use S3 Batch Operations with AWS Lambda to pre-generate thumbnail variants for all known resolutions. Configure a dynamic CloudFront origin to map requests to the appropriate pre-generated variant.

B

Use S3 Batch Operations with AWS Lambda to pre-generate thumbnail variants for all resolutions. Create a Lambda@Edge function to route requests to the correct pre-generated variant using request parameters.

C

Implement a Lambda@Edge function to generate optimized thumbnails on-demand for each request. Set CloudFront's TTL cache policy to its maximum value to reduce repeated processing.

D

Implement a Lambda@Edge function to generate optimized thumbnails on-demand and return them in the response. Store processed thumbnails in S3 within the same function to serve future requests directly.

Question #424 / 557

A developer is integrating Amazon API Gateway with an AWS Lambda function. After deploying the API, the developer notices that all requests result in a 502 Bad Gateway error. The Lambda function logs indicate that the function executed successfully. What should the developer do to resolve the error?

A

Ensure the API Gateway method uses an IAM role with permissions to invoke the Lambda function.

B

Modify the API Gateway to use a Lambda alias instead of the function's ARN.

C

Update the Lambda function to return a response in the format expected by API Gateway.

D

Adjust the timeout settings of the API Gateway integration to match the Lambda function's duration.
