• Question 542:

  Which AWS services can limit manual errors by consistently provisioning AWS resources in multiple envirom? (Select TWO.)

  A. AWS Config
  B. AWS CodeStar
  C. AWS CloudFormation
  D. AWS Cloud Development Kit (AWS CDK)
  E. AWS CodeBuild
  C. AWS CloudFormation
  D. AWS Cloud Development Kit (AWS CDK)

  ---

  Explanation

  AWS CloudFormation and AWS Cloud Development Kit (AWS CDK) are AWS services that can limit manual errors by consistently provisioning AWS resources in multiple environments. AWS CloudFormation is a service that enables you to model and provision AWS resources using templates. You can use AWS CloudFormation to define the AWS resources and their dependencies that you need for your applications, and to automate the creation and update of those resources across multiple environments, such as development, testing, and production. AWS CloudFormation helps you ensure that your AWS resources are configured consistently and correctly, and that you can easily replicate or modify them as needed. AWS Cloud Development Kit (AWS CDK) is a service that enables you to use familiar programming languages, such as Python, TypeScript, Java, and C#, to define and provision AWS resources. You can use AWS CDK to write code that synthesizes into AWS CloudFormation templates, and to leverage the existing libraries and tools of your preferred language. AWS CDK helps you reduce the complexity and errors of writing and maintaining AWS CloudFormation templates, and to apply the best practices and standards of software development to your AWS infrastructure.
