💡 Hint

Common Mistakes

Using -Confirm instead of -WhatIf shows a prompt instead of a simulation.

Using -Force or -Recurse does not simulate the action.

The -WhatIf parameter shows what would happen if the command runs, without making changes.

💡 Hint

Common Mistakes

Using -WhatIf only simulates the action without prompting.

Using -Force bypasses confirmation prompts.

The -Confirm parameter asks for user confirmation before running the command.

Fix the error in the function to support WhatIf and Confirm parameters correctly.

PowerShell

function Remove-MyFile {
    param(
        [string]$Path
    )
    Remove-Item -Path $Path [1]
}

💡 Hint

Common Mistakes

Using only -WhatIf or -Confirm without values inside a function.

Using -Force disables confirmation and simulation.

To support both WhatIf and Confirm, you must pass them as parameters with values.

4fill in blank

hard

Fill both blanks to add WhatIf and Confirm support to this advanced function.

PowerShell

function Remove-MyFolder {
    param(
        [string]$FolderPath,
        [switch]$WhatIf,
        [switch]$Confirm
    )
    Remove-Item -Path $FolderPath [1] [2]
}

Drag options to blanks, or click blank then click option'

A-WhatIf:$WhatIf

B-Confirm:$Confirm

C-Force

D-Recurse

Attempts:

3 left

💡 Hint

Common Mistakes

Hardcoding -WhatIf or -Confirm without using the parameters.

Forgetting to pass both parameters.

Pass the switches as parameter values to enable WhatIf and Confirm support dynamically.

5fill in blank

hard

Fill all three blanks to create a function that supports WhatIf and Confirm and uses them in Remove-Item.

PowerShell

function Remove-ItemSafe {
    param(
        [string]$TargetPath,
        [switch]$WhatIf,
        [switch]$Confirm
    )
    Remove-Item [1] [2] [3]
}

Drag options to blanks, or click blank then click option'

A-Path $TargetPath

B-Confirm:$Confirm

C-WhatIf:$WhatIf

D-Force

Attempts:

3 left

💡 Hint

Common Mistakes

Not passing the path parameter correctly.

Mixing up the order of parameters.

Not using the switch values with :$ syntax.

Pass the path and the switches $WhatIf and $Confirm to Remove-Item to support simulation and confirmation.
