💡 Hint

Common Mistakes

Using a cmdlet name instead of a URL string.

Forgetting to put the URL in quotes.

Using the wrong parameter like -Method POST instead of -Uri.

💡 Hint

Common Mistakes

Not quoting the header value causing errors.

Using single quotes which also work but the task expects double quotes.

The header value must be a string, so it needs to be enclosed in quotes. Option B correctly uses double quotes.

4fill in blank

hard

Fill both blanks to create a REST API call that sends JSON data with a custom header.

PowerShell

$headers = @{ "Content-Type" = [1] }
Invoke-RestMethod -Uri "https://api.example.com/update" -Method [2] -Headers $headers -Body $jsonPayload

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

A"application/json"

BPOST

CGET

D"text/plain"

💡 Hint

Common Mistakes

Using GET method when sending data.

Setting Content-Type to text/plain instead of application/json.

The Content-Type header should be set to application/json when sending JSON data. The HTTP method to send data is POST.

5fill in blank

hard

Fill all three blanks to parse JSON response and extract a property value.

PowerShell

$response = Invoke-RestMethod -Uri "https://api.example.com/info"
$value = $response.[1]
if ($value -eq [2]) {
    Write-Output [3]
}

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

B"success"

C"Operation completed"

Ddata

💡 Hint

Common Mistakes

Using incorrect property names.

Forgetting quotes around string values.

Not outputting a string message.

The code extracts the status property from the JSON response. It checks if it equals the string "success", then outputs a message.
