Question 194

A company is developing a public web application that needs to access multiple AWS services. The application will have hundreds of users who must log in to the application first before using the services.

The company needs to implement a secure and scalable method to grant the web application temporary access to the AWS resources.

C.

Use AWS IAM Identity Center to create a user pool that includes the application users. Assign access credentials to the web application users. Use the credentials to access the required AWS services.

D.

Create an IAM user that has programmatic access keys for the AWS services. Store the access keys in AWS Systems Manager Parameter Store. Retrieve the access keys from Parameter Store. Use the keys in the web application.

Question 195

A company is building a new application that uses multiple serverless architecture components. The application architecture includes an Amazon API Gateway REST API and AWS Lambda functions to manage incoming requests.

The company needs a service to send messages that the REST API receives to multiple target Lambda functions for processing. The service must filter messages so each target Lambda function receives only the messages the function needs.

Which solution will meet these requirements with the LEAST operational overhead?

Options:

A.

Send the requests from the REST API to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe multiple Amazon Simple Queue Service (Amazon SQS) queues to the SNS topic. Configure the target Lambda functions to poll the SQS queues.

B.

Send the requests from the REST API to a set of Amazon EC2 instances that are configured to process messages. Configure the instances to filter messages and to invoke the target Lambda functions.

C.

Send the requests from the REST API to Amazon Managed Streaming for Apache Kafka (Amazon MSK). Configure Amazon MSK to publish the messages to the target Lambda functions.

D.

Send the requests from the REST API to multiple Amazon Simple Queue Service (Amazon SQS) queues. Configure the target Lambda functions to poll the SQS queues.
