A developer creates a customer managed key for multiple AWS users to encrypt data in Amazon S3. The developer configures Amazon Simple Notification Service (Amazon SNS) to publish a message if key deletion is scheduled. The developer needs to preserve any SNS messages that cannot be delivered so that those messages can be reprocessed.

Which AWS service or feature should the developer use to meet this requirement?

  1. Amazon Simple Email Service (Amazon SES)
  2. AWS Lambda
  3. Amazon Simple Queue Service (Amazon SQS)
  4. Amazon CloudWatch alarm

A developer needs to deploy an application to AWS Elastic Beanstalk for a company. The application consists of a single Docker image. The company's automated continuous integration and continuous delivery (CI/CD) process builds the Docker image and pushes the image to a public Docker registry.

How should the developer deploy the application to Elastic Beanstalk?

  1. Create a Dockerfile. Configure Elastic Beanstalk to build the application as a Docker image.
  2. Create a docker-compose.yml file. Use the Elastic Beanstalk CLI to deploy the application.
  3. Create a .zip file that contains the Docker image. Upload the .zip file to Elastic Beanstalk.
  4. Create a Dockerfile. Run the Elastic Beanstalk CLI eb local run command in the same directory.

A company is using AWS CodeDeploy for all production deployments. A developer has an Amazon Elastic Container Service (Amazon ECS) application that uses the CodeDeployDefault.ECSAIIAtOnce configuration. The developer needs to update the production environment in increments of 10% until the entire production environment is updated.

Which CodeDeploy configuration should the developer use to meet these requirements?

  1. CodeDeployDefault.ECSCanary10Percent5Minutes
  2. CodeDeployDefault.ECSLinear10PercentEvery3Minutes
  3. CodeDeployDefault.OneAtATime
  4. CodeDeployDefault.LambdaCanary10Percent5Minutes

A company is using AWS Elastic Beanstalk to deploy a three-tier application. The application uses an Amazon RDS DB instance as the database tier. The company wants to decouple the DB instance from the Elastic Beanstalk environment.

Which combination of steps should a developer lake to meet this requirement? (Choose two.)

  1. Create a new Elastic Beanstalk environment that connects to the DB instance.
  2. Create a new DB instance from a snapshot of the previous DB instance.
  3. Use the Elastic Beanstalk CLI to decouple the DB instance.
  4. Use the AWS CLI to decouple the DB instance.
  5. Modify the current Elastic Beanstalk environment to connect to the DB instance.

A company has point-of-sale devices across thousands of retail shops that synchronize sales transactions with a centralized system. The system includes an Amazon API Gateway API that exposes an AWS Lambda function. The Lambda function processes the transactions and stores the transactions in Amazon RDS for MySQL. The number of transactions increases rapidly during the day and is near zero at night.

How can a developer increase the elasticity of the system MOST cost-effectively?

  1. Migrate from Amazon RDS to Amazon Aurora MySQL. Use an Aurora Auto Scaling policy to scale road replicas based on CPU consumption.
  2. Migrate from Amazon RDS to Amazon Aurora MySQL. Use an Aurora Auto Scaling policy to scale read replicas based on the number of database connections.
  3. Create an Amazon Simple Queue Service (Amazon SQS) queue. Publish transactions to the queue. Set the queue to invoke the Lambda function. Turn on enhanced fanout for the Lambda function.
  4. Create an Amazon Simple Queue Service (Amazon SQS) queue. Publish transactions to the queue. Set the queue to invoke the Lambda function. Set the reserved concurrency of the Lambda function to be less than the number of database connections.
