Given these two arrays in PowerShell:

$baseline = @('Setting1', 'Setting2', 'Setting3')
$current = @('Setting1', 'Setting2', 'Setting4')

What will be the output of Compare-Object $baseline $current?

ASetting1 and Setting2 are different

BNo differences found

CSetting3 is in baseline only; Setting4 is in current only

DError: Cannot compare arrays

Step-by-Step Solution

Solution:

Step 1: Compare the two arrays
Baseline has Setting3; current has Setting4 instead. Setting1 and Setting2 are common.
Step 2: Understand Compare-Object output
It shows items only in one array with a side indicator. So Setting3 appears only in baseline, Setting4 only in current.
Final Answer:
Setting3 is in baseline only; Setting4 is in current only -> Option C
Quick Check:
Compare-Object shows differences = Setting3 is in baseline only; Setting4 is in current only [OK]

Quick Trick: Look for items unique to each list [OK]
