Question 49

A solutions architect needs to run a PowerShell script on a fleet of Amazon EC2 instances running Microsoft Windows. The instances have already been launched in an Amazon VPC. What tool can be run from the AWS Management Console that can execute the script on all target EC2 instances?

  1. AWS CodeDeploy
  2. AWS Config
  3. Run Command
  4. AWS OpsWorks

Correct Answer: 3

Explanation: Run Command is designed to support a wide range of enterprise scenarios, including installing software, running ad hoc scripts or Microsoft PowerShell commands, configuring Windows Update settings, and more.

Run Command can be used to implement configuration changes across Windows instances on a consistent yet ad hoc basis and is accessible from the AWS Management Console, the AWS Command Line Interface (CLI), the AWS Tools for Windows PowerShell, and the AWS SDKs.

INCORRECT:AWS CodeDeploy” is incorrect. AWS CodeDeploy is a deployment service that automates application deployments to Amazon EC2 instances, on-premises instances, serverless Lambda functions, or Amazon ECS services.

INCORRECT:AWS Config” is incorrect. AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. It is not used for ad-hoc script execution.

CORRECT: “Run Command” is the correct answer.

INCORRECT:AWS OpsWorks” is incorrect. AWS OpsWorks provides instances of managed Puppet and Chef.
