1fill in blank

easy

Complete the code to filter processes with CPU usage greater than 100.

Drag options to blanks, or click blank then click option'

A-gt

B-lt

C-ne

D-eq

💡 Hint

Common Mistakes

Using '-lt' which means 'less than' and would filter the wrong processes.

Using '-eq' which means 'equals' and might filter too few processes.

The operator -gt means 'greater than' in PowerShell, so it filters processes with CPU usage greater than 100.

Complete the code to filter services that are running.

PowerShell

Get-Service | Where-Object { $_.Status [1] 'Running' }

Drag options to blanks, or click blank then click option'

A-lt

B-ne

C-eq

D-gt

💡 Hint

Common Mistakes

Using '-ne' which means 'not equal' and would filter services that are not running.

Using '-lt' or '-gt' which are for numeric comparisons, not strings.

The operator -eq means 'equals' in PowerShell, so it filters services whose status is exactly 'Running'.

Fix the error in the code to filter files larger than 1MB.

PowerShell

Get-ChildItem | Where-Object { $_.Length [1] 1MB }

Drag options to blanks, or click blank then click option'

B-gt

C-eq

D-lt

💡 Hint

Common Mistakes

Using '-lt' which means 'less than' and would filter smaller files.

Using '-eq' which means 'equals' and might filter no files.

The operator -gt means 'greater than' in PowerShell, so it filters files larger than 1MB.

4fill in blank

hard

Fill both blanks to filter processes with names starting with 'S' and CPU usage less than 50.

PowerShell

Get-Process | Where-Object { $_.ProcessName [1] 'S*' -and $_.CPU [2] 50 }

Drag options to blanks, or click blank then click option'

A-like

B-eq

C-lt

D-gt

Attempts:

💡 Hint

Common Mistakes

Using '-eq' instead of '-like' for pattern matching.

Using '-gt' instead of '-lt' for CPU comparison.

-like is used for pattern matching with wildcards, so it filters process names starting with 'S'. -lt means 'less than', so it filters CPU usage less than 50.

5fill in blank

hard

Fill all three blanks to create a dictionary of process names and their CPU usage, filtering only those with CPU usage greater than 10.

PowerShell

$result = @{ [1] = [2].ProcessName; [3] = [2].CPU } | Where-Object { [2].CPU -gt 10 }

Drag options to blanks, or click blank then click option'

AName

B$process

CCPU

D-gt

💡 Hint

Common Mistakes

Using wrong variable names or keys.

Using '-lt' instead of '-gt' for filtering CPU usage.

This code creates a dictionary with keys 'Name' and 'CPU' from each process object stored in '$process'. It filters processes with CPU usage greater than 10 using '-gt'.
