Challenge - 5 Problems

💻 Command Output

What is the output of this PowerShell command?

Consider the following PowerShell command that lists services and filters only those that are running. What will be the output?

PowerShell

Get-Service | Where-Object { $_.Status -eq 'Running' } | Select-Object -First 3 -Property Name, Status

A List of all services regardless of status

B [{Name: 'Audiosrv', Status: 'Running'}, {Name: 'Dhcp', Status: 'Running'}, {Name: 'Dnscache', Status: 'Running'}]

C Error: 'Where-Object' is not recognized

D Empty list because no services are running

💡 Hint

Think about how the command filters services by their status and selects only the first three.

The command gets all services, filters those with Status 'Running', then selects the first three with their Name and Status properties. So the output is a list of three running services.

Why is PowerShell preferred for automating admin tasks?

Which of the following reasons best explains why PowerShell is widely used to automate administrative tasks?

A It uses a simple text-based scripting language that can interact with system components and supports objects.

B It only works on Windows and cannot access system settings.

C It requires complex graphical interfaces to run scripts.

D It cannot automate tasks and is only for manual commands.

💡 Hint

Think about how PowerShell handles data and system control.

PowerShell uses an object-based scripting language that can access and control system components easily, making it ideal for automation.

Identify the error in this PowerShell script

This script is intended to stop all running services whose names start with 'A'. Which of the following is true?

PowerShell

Get-Service A* | Where-Object { $_.Status -eq 'Running' } | Stop-Service

A Error: 'Get-Service' does not accept wildcards directly.

B Error: 'Where-Object' is misspelled causing a command not found.

C Error: 'Stop-Service' requires confirmation and will fail silently.

D No error; script stops all running services starting with 'A'.

💡 Hint

Check if 'Get-Service' supports wildcards in its parameters.

No error; 'Get-Service' accepts wildcards directly in the service name parameter (positional argument). The script gets services starting with 'A', filters running ones, then stops them (may prompt for confirmation unless -Force is used).

How to automate user account creation with PowerShell?

You want to create multiple user accounts in Active Directory using PowerShell. Which approach below correctly automates this task?

A Use a CSV file with user details and a script that reads the file and runs New-ADUser for each entry.

B Write a script that only prints user names without creating accounts.

C Manually open Active Directory Users and Computers and create each user one by one.

D Use PowerShell to delete existing users instead of creating new ones.

💡 Hint

Think about how to handle multiple users efficiently with PowerShell.

Automating user creation is best done by reading user info from a CSV and running New-ADUser in a loop.

📝 Syntax

Which PowerShell snippet correctly outputs the names of running services in alphabetical order?

Select the snippet that lists only running services and sorts their names alphabetically.

A Get-Service | Where-Object { $_.Status = 'Running' } | Sort-Object Name | Select-Object Name

B Get-Service | Sort-Object Status | Where-Object { $_.Status -eq 'Running' } | Select-Object Name

C Get-Service | Where-Object { $_.Status -eq 'Running' } | Sort-Object Name | Select-Object -Property Name

D Get-Service | Select-Object Name | Where-Object { $_.Status -eq 'Running' } | Sort-Object Name

💡 Hint

Remember the correct operator for comparison and the order of filtering and sorting.

Option C correctly filters running services, sorts by Name, then selects the Name property. Option C sorts before filtering, which is less efficient. Option C tries to filter after selecting Name only, losing Status info. Option C uses '=' instead of '-eq' causing assignment error.
