Practice

1. What does the PowerShell command Get-Service do?

easy

A. It shows the status of services on the computer.

B. It starts a stopped service.

C. It stops a running service.

D. It deletes a service from the system.

Solution

1. Step 1: Understand the purpose of Get-Service

   The Get-Service command lists services and their current status (running or stopped).

2. Step 2: Compare with other commands

   Start-Service and Stop-Service change service states, but Get-Service only shows status.

3. Final Answer:

   It shows the status of services on the computer. -> Option A

4. Quick Check:

   Get-Service = Show service status [OK]

Hint: Get-Service always lists service status, not start or stop [OK]

Common Mistakes:

• Confusing Get-Service with Start-Service
• Thinking Get-Service stops services
• Assuming Get-Service deletes services

2. Which of the following is the correct syntax to start a service named 'Spooler' in PowerShell?

easy

A. Start-Service -Name Spooler

B. Get-Service -Start Spooler

C. Stop-Service -Name Spooler

D. Start-Service Spooler -Force

Solution

1. Step 1: Identify the correct cmdlet for starting a service

   Start-Service is used to start services, and it accepts the -Name parameter to specify the service.

2. Step 2: Check the syntax correctness

   Start-Service -Name Spooler is the correct syntax. Get-Service -Start Spooler uses wrong cmdlet and parameter, Stop-Service -Name Spooler stops service, and Start-Service Spooler -Force uses an invalid parameter -Force.

3. Final Answer:

   Start-Service -Name Spooler -> Option A

4. Quick Check:

   Start-Service -Name ServiceName = Start service [OK]

Hint: Use Start-Service with -Name to start a service [OK]

Common Mistakes:

• Using Get-Service to start a service
• Using Stop-Service instead of Start-Service
• Adding invalid parameters like -Force

3. What will be the output of this PowerShell command?

Get-Service -Name W32Time | Select-Object -Property Status

medium

A. Starts the W32Time service.

B. Displays the status (Running or Stopped) of the W32Time service.

C. Stops the W32Time service.

D. Shows an error because Select-Object cannot be used here.

Solution

1. Step 1: Understand Get-Service with Select-Object

   Get-Service -Name W32Time fetches the service object, and piping it to Select-Object -Property Status extracts only the status property.

2. Step 2: Determine the output

   The output will be a simple display showing the status of the W32Time service, such as Running or Stopped.

3. Final Answer:

   Displays the status (Running or Stopped) of the W32Time service. -> Option B

4. Quick Check:

   Get-Service + Select-Object = Show service status [OK]

Hint: Get-Service piped to Select-Object shows specific properties [OK]

Common Mistakes:

• Thinking it starts or stops the service
• Believing Select-Object causes an error here
• Confusing service name with command parameters

4. You run this command to stop the 'Spooler' service:

Stop-Service Spooler

But it fails with an error. What is the likely cause?

medium

A. You need to specify the parameter name: -Name before the service name.

B. The service is already stopped, so Stop-Service cannot run.

C. Stop-Service cannot stop the Spooler service.

D. You must run PowerShell as Administrator to stop services.

Solution

1. Step 1: Check command syntax

   Stop-Service Spooler is valid because the parameter -Name is positional and can be omitted.

2. Step 2: Consider permissions

   Stopping services usually requires administrator rights. Without running PowerShell as admin, the command fails with an error.

3. Final Answer:

   You must run PowerShell as Administrator to stop services. -> Option D

4. Quick Check:

   Stopping services needs admin rights [OK]

Hint: Run PowerShell as admin to stop services [OK]

Common Mistakes:

• Thinking -Name parameter is mandatory
• Assuming service must be running to stop
• Believing Spooler service cannot be stopped

5. You want to write a script that checks if the 'W32Time' service is stopped, and if so, starts it. Which script snippet correctly does this?

hard

A. Start-Service -Name W32Time -IfStopped

B. if (Get-Service W32Time -Status 'Stopped') { Start-Service W32Time }

C. $svc = Get-Service -Name W32Time
if ($svc.Status -eq 'Stopped') { Start-Service -Name W32Time }

D. $svc = Get-Service W32Time
if ($svc.Status = 'Stopped') { Start-Service W32Time }

Solution

1. Step 1: Retrieve the service object and check status

   Using $svc = Get-Service -Name W32Time stores the service object. Then $svc.Status -eq 'Stopped' correctly compares the status.

2. Step 2: Start the service if stopped

   If the status is 'Stopped', Start-Service -Name W32Time starts the service.

3. Final Answer:

   $svc = Get-Service -Name W32Time if ($svc.Status -eq 'Stopped') { Start-Service -Name W32Time } -> Option C

4. Quick Check:

   Check status with -eq, then start service [OK]

Hint: Use -eq to compare status, then Start-Service if stopped [OK]

Common Mistakes:

• Using single = instead of -eq for comparison
• Assuming Start-Service has -IfStopped parameter
• Trying to filter Get-Service with -Status parameter
