What is the output of this PowerShell command?

You run the command Install-Module -Name Pester -Scope CurrentUser -Force on a system where Pester is already installed for the current user. What will happen?

PowerShell

Install-Module -Name Pester -Scope CurrentUser -Force

A The Pester module is reinstalled without asking for confirmation.

B An error occurs because the module is already installed.

C The command prompts to confirm overwriting the existing module.

Which command correctly installs a module for all users without prompts?

Choose the correct PowerShell command to install the module 'Az' for all users and suppress any confirmation prompts.

Why does this Install-Module command fail with an error?

You run the command Install-Module -Name AzureAD -Scope AllUsers but get an error saying you do not have permission to install for all users. What is the most likely cause?

PowerShell

Install-Module -Name AzureAD -Scope AllUsers

A You need to run PowerShell as Administrator to install modules for all users.

B The module AzureAD does not support installation for all users.

C The -Scope parameter is invalid and should be omitted.

D The module is already installed for the current user, so installation is blocked.

💡 Hint

Think about permissions required for system-wide changes.

Installing modules for all users requires administrator privileges, so PowerShell must be run as Administrator.
