💼 Career

Knowing how to use Invoke-Command is essential for IT professionals managing Windows networks and automating remote tasks.

1

Set the remote computer name

Create a variable called $computerName and set it to the string "Server01".

PowerShell

# Create a variable called $computerName and set it to "Server01"
# Your code here

Need a hint?

Use = to assign the string "Server01" to the variable $computerName.

2

Create the script block with the command

Create a variable called $scriptBlock and assign it a script block that runs the command Get-ComputerInfo.

PowerShell

$computerName = "Server01"
# Create a variable called $scriptBlock with a script block running Get-ComputerInfo
# Your code here

Need a hint?

Use curly braces { } to create a script block and put Get-ComputerInfo inside.

3

Run Invoke-Command on the remote computer

Use Invoke-Command with the -ComputerName parameter set to $computerName and the -ScriptBlock parameter set to $scriptBlock. Store the result in a variable called $result.

PowerShell

$computerName = "Server01"
$scriptBlock = { Get-ComputerInfo }
# Use Invoke-Command with -ComputerName $computerName and -ScriptBlock $scriptBlock, store output in $result
# Your code here

Need a hint?

Use Invoke-Command with the parameters exactly as shown and assign the output to $result.

4

Display the output of the remote command

Print the contents of the variable $result to show the remote computer information.

PowerShell

$computerName = "Server01"
$scriptBlock = { Get-ComputerInfo }
$result = Invoke-Command -ComputerName $computerName -ScriptBlock $scriptBlock
# Print the $result variable
# Your code here

Need a hint?

Simply type $result on a line by itself to display the output.
