💡 Hint

Common Mistakes

Using 'Exit' or 'Throw' inside catch which stops the script.

Not using quotes around the message string.

The catch block handles the error and prints a message, so the script does not stop.

💡 Hint

Common Mistakes

Using 'Stop' which halts the script on error.

Using 'Continue' which still shows errors.

The -ErrorAction SilentlyContinue option tells PowerShell to ignore errors and keep running.

hard

Fix the error in the code to handle exceptions properly.

PowerShell

try {
    Remove-Item 'C:\protectedfile.txt'
} catch [1] {
    Write-Host 'Cannot delete file.'

💡 Hint

Common Mistakes

Omitting square brackets around the exception type.

Using parameters like -ErrorAction inside catch parentheses.

The catch block needs an exception type in square brackets to catch specific errors.

4fill in blank

hard

Fill both blanks to create a try-catch block that logs errors and continues.

PowerShell

try {
    [1] 'C:\file.txt' -ErrorAction Stop
} catch [Exception] {
    [2] 'Error logged, continuing script.'
}

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

AGet-Content

BWrite-Host

CWrite-Output

DRemove-Item

Attempts:

💡 Hint

Common Mistakes

Using Remove-Item instead of Get-Content in try.

Using Write-Output instead of Write-Host in catch.

Get-Content reads the file, and Write-Host shows the error message so the script continues.

5fill in blank

hard

Fill all three blanks to handle errors and assign a default value.

PowerShell

$content = try {
    [1] 'C:\data.txt' -ErrorAction Stop
} catch {
    [2] = 'Default content'
    [3]
}

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

AGet-Content

B$content

DWrite-Host 'Using default content'; $content

Attempts:

3 left

💡 Hint

Common Mistakes

Not assigning the default value to the variable.

Not printing a message in catch.

The try block reads the file. On error, the catch assigns a default string to $content and prints a message.
