1fill in blank

easy

PowerShell

Get-Date | [1]

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

AGet-Content

BOut-File

CStart-Process

DWrite-Output

Attempts:

💡 Hint

Common Mistakes

Using Out-File writes to a file instead of showing output.

Using Start-Process starts a new process, not for output.

Using Get-Content reads from files, not for output.

The Write-Output cmdlet sends the output to the console, showing the current date and time.

medium

Complete the code to list all running processes in PowerShell.

PowerShell

[1]

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

AGet-Process

BStart-Process

CGet-Service

DStop-Process

Attempts:

3 left

💡 Hint

Common Mistakes

Using Get-Service lists services, not processes.

Using Start-Process starts a new process, not lists them.

Using Stop-Process stops a process, not lists them.

Get-Process lists all running processes on your computer.

3fill in blank

hard

Fix the error in the code to read the content of a file named 'log.txt'.

PowerShell

Get-Content [1]

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

A-File log.txt

Blog.txt

C-Path log.txt

DPath log.txt

Attempts:

3 left

💡 Hint

Common Mistakes

Using -Path log.txt works but is not needed here.

Using -File log.txt is not a valid parameter.

Using Path log.txt causes syntax error.

You can pass the file name directly to Get-Content to read its content.

4fill in blank

hard

Fill both blanks to filter processes with CPU usage greater than 100.

PowerShell

Get-Process | Where-Object { $_.CPU [1] [2] }

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

A>

B100

C<

D50

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' instead of '>' reverses the filter.

Using '50' instead of '100' changes the threshold.

The Where-Object filters processes where CPU is greater than 100.

5fill in blank

hard

Fill all three blanks to create a hashtable of process names and their IDs for processes using more than 50 CPU.

PowerShell

$result = @{}; foreach ($p in Get-Process | Where-Object { $_.CPU [3] 50 }) { $result[[1]] = [2] }

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

A$p.Name

B$p.Id

C>

D$p.CPU

Attempts:

3 left

💡 Hint

Common Mistakes

Using $p.Id as key and $p.Name as value swaps keys and values.

Using '<' instead of '>' changes the filter logic.

Using $p.CPU as key or value is incorrect.

This creates a hashtable where keys are process names and values are process IDs for processes with CPU usage greater than 50.
