What is SSH-based remoting in PowerShell 7+?

SSH-based remoting allows you to run PowerShell commands on a remote computer securely using the SSH protocol. It works across different platforms like Windows, Linux, and macOS.

How do you start an SSH-based PowerShell session to a remote computer?

Use the command: Enter-PSSession -HostName <remote-computer> -UserName <user>. This opens an interactive session over SSH.

intermediate

What must be installed and configured on the remote machine to use SSH-based remoting?

The remote machine must have an SSH server running and PowerShell 7+ installed. The SSH server handles the connection securely.

Which PowerShell cmdlet is used to run a command on a remote computer over SSH without entering an interactive session?

Use Invoke-Command -HostName <remote-computer> -UserName <user> -ScriptBlock { <commands> } to run commands remotely over SSH.

Why is SSH-based remoting preferred over older PowerShell remoting methods on non-Windows systems?

SSH-based remoting works cross-platform and uses a secure, widely supported protocol. It does not require Windows-only services like WinRM, making it simpler and more compatible.

Which cmdlet starts an interactive SSH-based PowerShell session?

A New-PSSession -ComputerName remote

B Enter-PSSession -HostName remote -UserName user

C Invoke-Command -ComputerName remote -ScriptBlock { }

D Start-SSHSession -Computer remote

Enter-PSSession with -HostName and -UserName parameters starts an interactive SSH session in PowerShell 7+.

What protocol does PowerShell 7+ use for SSH-based remoting?

A SSH

B RDP

C Telnet

D WinRM

SSH-based remoting uses the SSH protocol, which is secure and cross-platform.

Which of these is NOT required for SSH-based remoting?

A WinRM service running on remote machine

B SSH server on remote machine

C PowerShell 7+ installed on remote machine

D Network access between client and remote machine

WinRM is not needed for SSH-based remoting; SSH server replaces it.

How do you run a script block remotely over SSH without an interactive session?

A New-PSSession -ComputerName remote

B Enter-PSSession -HostName remote

C Start-Process -FilePath script.ps1

D Invoke-Command -HostName remote -UserName user -ScriptBlock { commands }

Invoke-Command with -HostName and -UserName runs commands remotely over SSH without interactive session.

Why is SSH-based remoting useful on Linux systems?

A Because it uses Telnet protocol

B Because WinRM is native on Linux

C Because SSH is widely supported and secure on Linux

D Because it requires no authentication

SSH is the standard secure remote protocol on Linux, making SSH-based remoting ideal.

Explain how to set up and use SSH-based remoting in PowerShell 7+ to run commands on a remote machine.

Think about what software is needed and which commands start the remote session.

Describe the benefits of using SSH-based remoting over older PowerShell remoting methods.

Consider compatibility and security advantages.
