💡 Hint

Common Mistakes

Using catch without specifying Exception may not catch all terminating errors.

Using catch with 'Error' or 'Warning' is incorrect syntax.

The catch block catches terminating errors by specifying Exception.

💡 Hint

Common Mistakes

Using 'Stop' causes the script to stop on errors.

Using 'Continue' displays the error message but continues execution.

The -ErrorAction SilentlyContinue parameter suppresses non-terminating errors and continues execution silently.

Fix the error in the Try-Catch block to handle terminating errors properly.

PowerShell

try {
    Get-Item 'C:\nonexistentfile.txt' -ErrorAction [1]
} catch {
    Write-Host 'Caught error'
}

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

💡 Hint

Common Mistakes

Using SilentlyContinue prevents the error from being caught.

Using 'Continue' or 'Ignore' will not make the error terminating.

To make an error terminating and catch it, use -ErrorAction Stop.

Fill both blanks to create a hashtable of files with size greater than 1MB.

PowerShell

$files = Get-ChildItem | Where-Object { $_.Length [1] 1MB } | ForEach-Object { @{ Name = $_.Name; Size = $_.Length [2] 1MB } }

💡 Hint

Common Mistakes

Using < instead of > filters smaller files.

Using * instead of / causes incorrect size calculation.

The code filters files larger than 1MB using > and converts size to MB by dividing by 1MB.

Fill all three blanks to create a dictionary of file names and sizes for files larger than 500KB.

PowerShell

$result = @{
    [1] = Get-ChildItem | Where-Object { $_.Length [2] 500KB } | ForEach-Object { $_.Name }
    [3] = Get-ChildItem | Where-Object { $_.Length [2] 500KB } | ForEach-Object { $_.Length }
}

💡 Hint

Common Mistakes

Using < instead of > filters smaller files.

Mixing up dictionary keys causes confusion.

The dictionary keys are Files and Size. The filter uses > to select files larger than 500KB.
