You have deployed a Windows Server instance (x86_64) in AWS EC2. After the instance has run for a week, you realized that you needed to run a script in PowerShell. You were logged in the AWS EC2 console and started using Systems Manager to run a command. You chose the command as "AWS-RunPowerShellScript". However, your instance cannot be selected as the target. How should you troubleshoot the issue so that the command can run in the current Windows instance successfully? (Select TWO.)

Answer options:

A.Change the command “AWS-RunPowerShellScript” to “AWS-RunShellScript”.
B.Systems Manager Run Command only works for Linux instances so that the Windows instance is unavailable.
C.Check if the latest version of SSM (AWS Systems Manager) Agent is installed on the Windows instance.
D.Check if the Windows instance has the latest system patches installed.
E.Verify that the instance has configured with the IAM role that enables it to communicate with the Systems Manager API.

Correct Answer – C, E
AWS Systems Manager Run Command is a service to run a command for Windows or Linux instance:
However, if the instance cannot be seen as the target for the command to run, some items must be checked according to https://docs.aws.amazon.com/systems-manager/latest/userguide/troubleshooting-remote-commands.html?icmpid=docs_ec2_console.
Option A is incorrect: Because “AWS-RunPowerShellScript” is correct while “AWS-RunShellScript” is for Linux instance.
Option B is incorrect: Because the Windows instance is supported. Check https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-prereqs.html for the supported Operating Systems.
Option C is CORRECT: Because only Amazon EC2 Windows Amazon Machine Images (AMIs) and certain Linux AMIs are pre-configured with the SSM Agent. You need to check if the SSM Agent is properly installed.
Option D is incorrect: Because system patches do not impact the SSM connection.
Option E is CORRECT: Because a proper IAM instance role is required; otherwise, EC2 cannot communicate with SSM API.
