You want to create a script that accepts a mandatory string parameter FilePath and an optional switch parameter Verbose. Which is the correct way to declare these parameters?

Aparam([Parameter(Mandatory=$true)][string]$FilePath, [switch]$Verbose)

Bparam([string]$FilePath, [switch]$Verbose = $true)

Cparam([string]$FilePath = Mandatory, [bool]$Verbose)

Dparam([Mandatory]$FilePath, [switch]$Verbose)

Step-by-Step Solution

Solution:

Step 1: Understand mandatory parameter syntax
Use the [Parameter(Mandatory=$true)] attribute to make a parameter required.
Step 2: Recognize switch parameter declaration
Switch parameters are declared with [switch] and do not need default values.
Step 3: Evaluate options
param([Parameter(Mandatory=$true)][string]$FilePath, [switch]$Verbose) correctly uses mandatory attribute and switch type; others misuse syntax or attributes.
Final Answer:
param([Parameter(Mandatory=$true)][string]$FilePath, [switch]$Verbose) -> Option A
Quick Check:
Mandatory attribute + switch type = correct declaration [OK]

Quick Trick: Use [Parameter(Mandatory=$true)] for required params [OK]

Common Mistakes:

Setting switch default to true
Using 'Mandatory' as default value
Omitting $ in attributes
