Monitoring scripts with email alerts in PowerShell - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to send an email alert using PowerShell's Send-MailMessage cmdlet.

PowerShell

Send-MailMessage -To "[e-mail]" -From "[e-mail]" -Subject "Alert" -Body "Disk space low" -SmtpServer [1]

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

Amailserver

Blocalhost

C192.168.1.1

Dsmtp.example.com

💡 Hint

Common Mistakes

Using 'localhost' when no SMTP server is running locally

Using an IP address that is not the SMTP server

Leaving the SMTP server blank

The -SmtpServer parameter requires the SMTP server address to send the email. "smtp.example.com" is a valid SMTP server address.

Complete the code to check if free disk space on C: drive is less than 10 GB.

PowerShell

$freeSpace = (Get-PSDrive -Name C).Free; if ($freeSpace [1] 10GB) { Write-Output "Low disk space" }

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

💡 Hint

Common Mistakes

Using '-gt' which means greater than

Using '-eq' which means equal

Using '-ne' which means not equal

The operator -lt means 'less than'. We want to check if free space is less than 10GB.

hard

Fix the error in the script to send an email alert only if disk space is low.

PowerShell

if ($freeSpace [1] 5GB) { Send-MailMessage -To "[e-mail]" -From "[e-mail]" -Subject "Disk Alert" -Body "Disk space critically low" -SmtpServer "smtp.example.com" }

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

A-gt

B-lt

C-eq

D-ne

💡 Hint

Common Mistakes

Using '-gt' which triggers alert when space is more than 5GB

Using '-eq' which triggers alert only if exactly 5GB

Using '-ne' which triggers alert for any value except 5GB

The condition should check if free space is less than 5GB to trigger the alert, so -lt is correct.

4fill in blank

hard

Fill both blanks to create a hashtable with drive letter as key and free space as value, filtering drives with more than 20GB free.

PowerShell

$drives = Get-PSDrive | Where-Object { $_.Free [1] 20GB } | ForEach-Object { @{ $_.Name = $_.Free [2] } }

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

A-gt

B-lt

C=

D==

💡 Hint

Common Mistakes

Using '-lt' instead of '-gt' for filtering

Using '==' instead of '=' for assignment

Confusing comparison and assignment operators

The filter uses -gt to select drives with free space greater than 20GB. The hashtable uses = to assign the free space value to the drive letter key.

5fill in blank

hard

Fill the blanks to create a script that checks disk space, sends alert if below threshold, and logs the event.

PowerShell

$threshold = 15GB
$freeSpace = (Get-PSDrive -Name D).Free
if ($freeSpace [1] $threshold) {
    Send-MailMessage -To "[e-mail]" -From "[e-mail]" -Subject "Disk Alert" -Body "Drive D low space" -SmtpServer [2]
    Add-Content -Path "C:\Logs\disk_alert.log" -Value "Drive D low space at $(Get-Date)"
}
else {
    Write-Output "Disk space sufficient"
}

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

A-lt

Bsmtp.example.com

C-gt

Dlocalhost

Attempts:

3 left

💡 Hint

Common Mistakes

Using '-gt' instead of '-lt' in the condition

Using wrong SMTP server address

Confusing log file path with SMTP server

The condition uses -lt to check if free space is less than threshold. The SMTP server is "smtp.example.com" to send the email.
