Question 96

A developer is creating an application that will give users the ability to store photos from their cellphones in the cloud. The application needs to support tens of thousands of users. The application uses an Amazon API Gateway REST API that is integrated with AWS Lambda functions to process the photos. The application stores details about the photos in Amazon DynamoDB.

Users need to create an account to access the application. In the application, users must be able to upload photos and retrieve previously uploaded photos. The photos will range in size from 300 KB to 5 MB.

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

Options:

Use Amazon Cognito user pools to manage user accounts. Create an Amazon Cognito user pool authorizer in API Gateway to control access to the API. Use the Lambda function to store the photos and details in the DynamoDB table. Retrieve previously uploaded photos directly from the DynamoDB table.

Use Amazon Cognito user pools to manage user accounts. Create an Amazon Cognito user pool authorizer in API Gateway to control access to the API. Use the Lambda function to store the photos in Amazon S3. Store the object ' s S3 key as part of the photo details in the DynamoDB table. Retrieve previously uploaded photos by querying DynamoDB for the S3 key.

Create an IAM user for each user of the application during the sign-up process. Use IAM authentication to access the API Gateway API. Use the Lambda function to store the photos in Amazon S3. Store the object ' s S3 key as part of the photo details in the DynamoDB table. Retrieve previously uploaded photos by querying DynamoDB for the S3 key.

Create a users table in DynamoDB. Use the table to manage user accounts. Create a Lambda authorizer that validates user credentials against the users table. Integrate the Lambda authorizer with API Gateway to control access to the API. Use the Lambda function to store the photos in Amazon S3. Store the object ' s S3 key as par of the photo details in the DynamoDB table. Retrieve previously uploaded photos by querying DynamoDB for the S3 key

Question 97

An online sales company is developing a serverless application that runs on AWS. The application uses an AWS Lambda function that calculates order success rates and stores the data in an Amazon DynamoDB table. A developer wants an efficient way to invoke the Lambda function every 15 minutes.

Which solution will meet this requirement with the LEAST development effort?

Options:

Create an Amazon EventBridge rule that has a rate expression that will run the rule every 15 minutes. Add the Lambda function as the target of the EventBridge rule.

Create an AWS Systems Manager document that has a script that will invoke the Lambda function on Amazon EC2. Use a Systems Manager Run Command task to run the shell script every 15 minutes.

Create an AWS Step Functions state machine. Configure the state machine to invoke the Lambda function execution role at a specified interval by using a Wait state. Set the interval to 15 minutes.

Provision a small Amazon EC2 instance. Set up a cron job that invokes the Lambda function every 15 minutes.

Question 98

A company offers a business-to-business software service that runs on dedicated infrastructure deployed in each customer ' s AWS account. Before a feature release, the company needs to run integration tests on real AWS test infrastructure. The test infrastructure consists of Amazon EC2 instances and an Amazon RDS database.

A developer must set up a continuous delivery process that will provision the test infrastructure across the different AWS accounts. The developer then must run the integration tests.

Which solution will meet these requirements with the LEAST administrative effort?

Options:

Use AWS CodeDeploy with AWS CloudFormation StackSets to deploy the infrastructure. Use Amazon CodeGuru to run the tests.

Use AWS CodePipeline with AWS CloudFormation StackSets to deploy the infrastructure. Use AWS CodeBuild to run the tests.

Use AWS CodePipeline with AWS CloudFormation change sets to deploy the infrastructure. Use a CloudFormation custom resource to run the tests.

Use AWS Serverless Application Model (AWS SAM) templates with AWS CloudFormation change sets to deploy the infrastructure. Use AWS CodeDeploy to run the tests.
