What is one real-life example of using a module?

Like a toolbox with labeled compartments, a module stores useful tools (functions) so you can grab what you need quickly instead of searching everywhere.

What can a PowerShell module contain?

A Only functions

B Only variables

C Functions, variables, and workflows

D Only scripts

Why is sharing code with modules better than copying code between scripts?

A Modules hide code from users

B Modules make code harder to read

C Modules slow down script execution

D Modules reduce errors and save time

Sharing code with modules avoids duplication, reducing errors and saving time.

Explain in your own words why modules are useful for packaging reusable code in PowerShell.

Think about how modules help avoid rewriting code and keep scripts clean.

Describe how you would use a PowerShell module in a real-life scripting task.

Imagine you have a set of functions you use often. How does a module help?
