Question 34 (Topic 1)

A company hosts its application in the us-west-1 Region. The company wants to add redundancy in the us-east-1 Region. The application secrets are stored in AWS Secrets Manager in us-west-1. A developer needs to replicate the secrets to us-east-1. Which solution will meet this requirement?

Select an option, then click Submit answer.

  • ○ Configure secret replication for each secret. Add us-east-1 as a replication Region. Choose an AWS Key Management Service (AWS KMS) key in us-east-1 to encrypt the replicated secrets.
  • ○ Create a new secret in us-east-1 for each secret. Configure secret replication in us-east-1. Set the source to be the corresponding secret in us-west-1. Choose an AWS Key Management Service (AWS KMS) key in us-west-1 to encrypt the replicated secrets.
  • ○ Create a replication rule for each secret. Set us-east-1 as the destination Region. Configure the rule to run during secret rotation. Choose an AWS Key Management Service (AWS KMS) key in us-east-1 to encrypt the replicated secrets.
  • ○ Create a Secrets Manager lifecycle rule to replicate each secret to a new Amazon S3 bucket in us-west-1. Configure an S3 replication rule to replicate the secrets to us-east-1.
Question 35 (Topic 1)

A developer needs to use a code template to create an automated deployment of an application onto Amazon EC2 instances. The template must be configured to repeat deployment, installation, and updates of resources for the application. The template must be able to create identical environments and roll back to previous versions. Which solution will meet these requirements?

Select an option, then click Submit answer.

  • ○ Use AWS Amplify for automatic deployment templates. Use a traffic-splitting deployment to copy any deployments. Modify any resources created by Amplify, if necessary.
  • ○ Use AWS CodeBuild for automatic deployment. Upload the required AppSpec file template. Save the appspec.yml file in the root directory folder of the revision. Specify the deployment group that includes the EC2 instances for the deployment.
  • ○ Use AWS CloudFormation to create an infrastructure template in JSON format to deploy the EC2 instances. Use CloudFormation helper scripts to install the necessary software and to start the application. Call the scripts directly from the template.
  • ○ Use AWS AppSync to deploy the application. Upload the template as a GraphQL schema. Specify the EC2 instances for deployment of the application. Use resolvers as a version control mechanism and to make any updates to the deployments.
Question 36 (Topic 1)

A company that has large online business uses an Amazon DynamoDB table to store sales data. The company enabled Amazon DynamoDB Streams on the table. The transaction status of each sale is stored in a TransactionStatus attribute in the table. The value of the TransactionStatus attribute must be either failed, pending, or completed. The company wants to be notified of failed sales where the Price attribute is above a specific threshold. A developer needs to set up notification for the failed sales. Which solution will meet these requirements with the LEAST development effort?

Select an option, then click Submit answer.

  • ○ Create an event source mapping between DynamoDB Streams and an AWS Lambda function. Use Lambda event filtering to trigger the Lambda function only if sales fail when the price is above the specified threshold. Configure the Lambda function to publish the data to an Amazon Simple Notification Service (Amazon SNS) topic.
  • ○ Create an event source mapping between DynamoDB Streams and an AWS Lambda function. Configure the Lambda function handler code to publish to an Amazon Simple Notification Service (Amazon SNS) topic if sales fail when price is above the specified threshold.
  • ○ Create an event source mapping between DynamoDB Streams and an Amazon Simple Notification Service (Amazon SNS) topic. Use event filtering to publish to the SNS topic if sales fail when the price is above the specified threshold.
  • ○ Create an Amazon CloudWatch alarm to monitor the DynamoDB Streams sales data. Configure the alarm to publish to an Amazon Simple Notification Service (Amazon SNS) topic if sales fail due when price is above the specified threshold.
