hard📝 Application Q15 of 15

PowerShell - Operators

A2..10 | ForEach-Object { $_ * 2 }

B2..10 | Where-Object { $_ % 2 -eq 0 }

C1..5 | Where-Object { $_ % 2 -eq 0 }

D2..10..2

Step-by-Step Solution

Solution:

Step 1: Understand the range and filtering
The range operator 2..10 creates numbers 2 to 10. Filtering with Where-Object { $_ % 2 -eq 0 } keeps only even numbers.
Step 2: Check each option
2..10 | Where-Object { $_ % 2 -eq 0 } correctly filters evens from 2 to 10. 2..10 | ForEach-Object { $_ * 2 } doubles numbers 2 to 10 (wrong). 1..5 | Where-Object { $_ % 2 -eq 0 } filters evens from 1 to 5 (wrong range). 2..10..2 uses invalid syntax (range operator does not support step).
Final Answer:
2..10 | Where-Object { $_ % 2 -eq 0 } -> Option B
Quick Check:
Filter evens from range with Where-Object [OK]

Quick Trick: Use Where-Object to filter even numbers after range [OK]
