Which bracket type denotes optional items in PowerShell syntax?

• A. Parentheses ()
• B. Curly braces {}
• C. Square brackets []
• D. Angle brackets <>

Answer: (C)

Square brackets indicate optional items in PowerShell syntax. When you see text inside square brackets, you can include that parameter or argument if you need extra functionality, but you’re not required to provide it for the command to run. For example, a command’s syntax may show [-Recurse], meaning you can add the -Recurse switch to enable recursive behavior, but omitting it still works. Other brackets have different roles: parentheses group expressions, curly braces denote script blocks or blocks of code, and angle brackets are often used in documentation to indicate required values or placeholders. So the bracket type that denotes optional items is square brackets.
