Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a scheduled task action that runs Notepad.

PowerShell

$action = New-ScheduledTaskAction -Execute [1]

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

Acmd.exe

Bcalc.exe

Cexplorer.exe

Dnotepad.exe

Attempts:

💡 Hint

Common Mistakes

Using the wrong executable name like 'calc.exe' or 'cmd.exe'.

Forgetting to specify the executable.

The New-ScheduledTaskAction cmdlet requires the executable to run. Here, notepad.exe is the correct program to launch Notepad.

Complete the code to register a scheduled task named 'MyTask' with the action stored in $action.

PowerShell

Register-ScheduledTask -TaskName 'MyTask' -Action [1] -Trigger $trigger

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

A$action

B$trigger

C$task

D$schedule

💡 Hint

Common Mistakes

Passing the trigger object instead of the action.

Using an undefined variable.

The -Action parameter expects the action object, which is stored in $action.

Fix the error in the code to create a daily trigger at 9 AM.

PowerShell

$trigger = New-ScheduledTaskTrigger -Daily -At [1]

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

A09:00

B9

C9 AM

D09:00AM

Attempts:

3 left

💡 Hint

Common Mistakes

Using '9' without minutes.

Using '9 AM' which is not the correct format.

The -At parameter requires a time in HH:mm format, so 09:00 is correct.

hard

Fill both blanks to create a scheduled task trigger that runs weekly on Monday at 8 AM.

PowerShell

$trigger = New-ScheduledTaskTrigger -Weekly -DaysOfWeek [1] -At [2]

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

AMonday

BTuesday

C08:00

D9:00

Attempts:

3 left

💡 Hint

Common Mistakes

Using the wrong day name.

Using incorrect time format like '9:00'.

The -DaysOfWeek parameter needs the day name, here Monday, and -At needs the time in HH:mm format, here 08:00.

5fill in blank

hard

Fill all three blanks to create a scheduled task with a daily trigger at 7 AM that runs PowerShell with a script path.

PowerShell

$action = New-ScheduledTaskAction -Execute [1] -Argument [2]
$trigger = New-ScheduledTaskTrigger -Daily -At [3]
Register-ScheduledTask -TaskName 'DailyScript' -Action $action -Trigger $trigger

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

Apowershell.exe

B-File C:\Scripts\daily.ps1

C07:00

D-Command "Get-Process"

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong executable or argument.

Incorrect time format.

Mixing up argument options.

The action runs powershell.exe with the argument to run a script file -File C:\Scripts\daily.ps1. The trigger is daily at 07:00.

Practice

1. What is the main purpose of a scheduled task in PowerShell?

easy

A. To monitor system performance continuously

B. To manually execute scripts only when needed

C. To run scripts or programs automatically at specific times

D. To edit files in the system

Solution

1. Step 1: Understand scheduled task purpose

   Scheduled tasks are designed to automate running scripts or programs without manual intervention.

2. Step 2: Compare options

   Only To run scripts or programs automatically at specific times describes automatic execution at set times, which matches scheduled tasks.

3. Final Answer:

   To run scripts or programs automatically at specific times -> Option C

4. Quick Check:

   Scheduled tasks automate running scripts [OK]

Hint: Scheduled tasks run automatically on a schedule [OK]

Common Mistakes:

• Confusing scheduled tasks with manual script runs
• Thinking scheduled tasks monitor system performance
• Assuming scheduled tasks edit files automatically

2. Which PowerShell cmdlet is used to create a new scheduled task trigger?

easy

A. New-ScheduledTaskTrigger

B. New-ScheduledTaskAction

C. Register-ScheduledTask

D. Get-ScheduledTask

Solution

1. Step 1: Identify cmdlet for trigger creation

   The cmdlet New-ScheduledTaskTrigger is specifically used to define when a scheduled task should run.

2. Step 2: Differentiate from other cmdlets

   New-ScheduledTaskAction defines what runs, Register-ScheduledTask registers the task, and Get-ScheduledTask retrieves tasks.

3. Final Answer:

   New-ScheduledTaskTrigger -> Option A

4. Quick Check:

   Trigger creation cmdlet = New-ScheduledTaskTrigger [OK]

Hint: Trigger means when task runs, use New-ScheduledTaskTrigger [OK]

Common Mistakes:

• Using New-ScheduledTaskAction instead of trigger cmdlet
• Confusing Register-ScheduledTask with trigger creation
• Trying to get tasks instead of creating triggers

3. What will the following PowerShell command output?

Get-ScheduledTask -TaskName 'MyTask' | Select-Object -ExpandProperty State

medium

A. The current state of the scheduled task named 'MyTask'

B. The list of all scheduled tasks on the system

C. The actions defined in the scheduled task

D. An error because Select-Object cannot expand properties

Solution

1. Step 1: Understand Get-ScheduledTask output

   Get-ScheduledTask with -TaskName returns the task object for 'MyTask'.

2. Step 2: Use Select-Object -ExpandProperty State

   This extracts the 'State' property value, showing the task's current status (e.g., Ready, Running).

3. Final Answer:

   The current state of the scheduled task named 'MyTask' -> Option A

4. Quick Check:

   Expanding State property shows task status [OK]

Hint: Select-Object -ExpandProperty extracts property value directly [OK]

Common Mistakes:

• Thinking it lists all tasks instead of one
• Confusing State with actions or triggers
• Assuming Select-Object cannot expand properties

4. You run this command but get an error:

Register-ScheduledTask -TaskName 'Backup' -Trigger $trigger -Action $action

What is the most likely cause?

medium

A. TaskName 'Backup' is already in use

B. PowerShell does not support Register-ScheduledTask

C. Register-ScheduledTask requires -User parameter

D. Variables $trigger or $action are not defined or invalid

Solution

1. Step 1: Check variables used in command

   $trigger and $action must be valid scheduled task trigger and action objects before registering.

2. Step 2: Understand error cause

   If these variables are missing or invalid, Register-ScheduledTask fails with an error.

3. Final Answer:

   Variables $trigger or $action are not defined or invalid -> Option D

4. Quick Check:

   Undefined variables cause Register-ScheduledTask error [OK]

Hint: Ensure $trigger and $action are created before registering task [OK]

Common Mistakes:

• Assuming task name conflict causes error
• Thinking -User parameter is always required
• Believing Register-ScheduledTask is unsupported in PowerShell

5. You want to create a scheduled task that runs a script every day at 6 AM. Which sequence of commands correctly sets this up?

hard

A. $action = New-ScheduledTaskTrigger -Daily -At 6am; $trigger = New-ScheduledTaskAction -Execute 'powershell.exe' -Argument '-File C:\Scripts\daily.ps1'; Register-ScheduledTask -TaskName 'DailyScript' -Trigger $trigger -Action $action

B. $trigger = New-ScheduledTaskTrigger -Daily -At 6am; $action = New-ScheduledTaskAction -Execute 'powershell.exe' -Argument '-File C:\Scripts\daily.ps1'; Register-ScheduledTask -TaskName 'DailyScript' -Trigger $trigger -Action $action

C. Register-ScheduledTask -TaskName 'DailyScript' -Trigger 'Daily' -Action 'powershell.exe -File C:\Scripts\daily.ps1'

D. $trigger = New-ScheduledTaskAction -Daily -At 6am; $action = New-ScheduledTaskTrigger -Execute 'powershell.exe' -Argument '-File C:\Scripts\daily.ps1'; Register-ScheduledTask -TaskName 'DailyScript' -Trigger $trigger -Action $action

Solution

1. Step 1: Create correct trigger and action objects

   New-ScheduledTaskTrigger defines when (daily at 6am), New-ScheduledTaskAction defines what (powershell.exe running script).

2. Step 2: Register the scheduled task with proper parameters

   Use Register-ScheduledTask with -TaskName, -Trigger, and -Action using the created objects.

3. Final Answer:

   Correct sequence is creating trigger then action, then registering task -> Option B

4. Quick Check:

   Trigger = when, Action = what, Register with both [OK]

Hint: Trigger sets time, Action sets program, Register combines both [OK]

Common Mistakes:

• Swapping trigger and action cmdlets
• Passing strings instead of objects to Register-ScheduledTask
• Omitting required parameters in Register-ScheduledTask
