PowerShell - Automation Patterns

Consider this PowerShell code:

$baseline = @('X','Y','Z')
$current = @('X','Y','W')
Compare-Object -ReferenceObject $baseline -DifferenceObject $current

What will be the output?

ANo differences found

BInputObject SideIndicator ---------- ------------- Z => W <=

CInputObject SideIndicator ---------- ------------- Z <= W =>

DError: Missing parameters

Step-by-Step Solution

Solution:

Step 1: Understand Compare-Object parameters
-ReferenceObject is the baseline; -DifferenceObject is the current state.
Step 2: Analyze differences
Z is in baseline but not current (<=), W is in current but not baseline (=>).
Final Answer:
InputObject SideIndicator
Z <=
W => -> Option C
Quick Check:
SideIndicator shows which array contains the item [OK]

Quick Trick: SideIndicator <= means baseline only, => means current only [OK]
