Question #325 / 1019

A company hosts a web application on Amazon S3, which uses Amazon Cognito for user authentication. Upon successful login, users receive a JSON Web Token (JWT) granting access to a protected DynamoDB table. However, users report errors when attempting to interact with the DynamoDB resources after deployment. A solutions architect must ensure proper permissions are configured to resolve the issue.

Which solution meets these requirements?

A

Modify the IAM role associated with the Amazon Cognito identity pool to include permissions for the DynamoDB table.

B

Update the DynamoDB resource policy to grant access directly to the Amazon Cognito user pool.

C

Redeploy the application to use AWS Lambda to handle DynamoDB access, bypassing IAM role permissions.

D

Configure the Cognito user pool with custom scopes to authorize access to the DynamoDB table.

Question #261 / 1019

They need to serve different content versions depending on whether users access the site via mobile devices or desktops.

Which two steps should a solutions architect take to meet this requirement? (Choose two.)

A

Configure Amazon CloudFront to cache separate content versions for mobile and desktop users.

B

Set up a host-based routing policy in the Application Load Balancer to direct traffic to different instance groups.

C

Use a Lambda@Edge function to inspect the User-Agent header and serve the corresponding content version.

D

Deploy AWS Global Accelerator with a Network Load Balancer configured for path-based routing to different EC2 instances.

Sample Questions

Question #311 / 557

A company has developed a serverless application for its online booking system. The application uses Amazon API Gateway for a REST API that triggers an AWS Lambda function. This function processes booking data, stores it in Amazon DynamoDB, and interacts with a third-party payment gateway API. The Lambda function returns an HTTP 200 status with no body once the payment is processed. During high traffic, the payment gateway API becomes overwhelmed, leading to errors. The company needs a solution that prevents exceeding the payment gateway's rate limits.

Which solution meets these requirements?

A

Modify the API Gateway to write requests directly into DynamoDB. Use a DynamoDB stream to invoke the Lambda function with reserved concurrency set to the payment gateway's limit. Process payments via the stream.

B

Configure API Gateway to send requests to an Amazon Kinesis Data Stream. Set the number of shards to match the payment gateway's threshold. Use Lambda with parallelization per shard to process records and interact with the payment API.

C

Set up API Gateway to write requests into an Amazon SQS queue. Configure the Lambda function with reserved concurrency equal to the payment gateway's limit. Process messages from the queue with this Lambda.

D

Direct API Gateway requests to an Amazon SNS topic. Use a Lambda function with provisioned concurrency set to the payment gateway's threshold. Subscribe Lambda to the SNS topic for message processing.

Question #470 / 557

A company uses Amazon API Gateway with an AWS Lambda integration for a backend process. The Lambda function must execute several sequential tasks that take up to 15 minutes to complete. Users report intermittent HTTP 504 errors from the API, but the Lambda logs show all invocations complete successfully.

Which solution will resolve the HTTP 504 errors?

A

Increase the timeout setting for the Lambda function.

B

Modify the Lambda function to use asynchronous invocation.

C

Configure the API Gateway to use an HTTP proxy integration.

D

Refactor the Lambda function to initiate an AWS Step Functions workflow.
