Evaluate the PowerShell syntax below:

$[$CmdletBinding$()]$

param $($

$[$Parameter $($Mandatory$=$$True$)]$

$[$ValidateSet $(219,220,221)]$

$[$String$]$ $ClassRoom

$)$

If the above PowerShell syntax was saved into a script file named ClassRoomScript.PS$1$ on the root of drive C:$\backslash ,$ what would be the result of typing the following syntax within another PowerShell console?

C:$\backslash$ ClassRoomScript.PS$1$ClassRoom $225$
