💡 Hint

Common Mistakes

Using 'int' or 'bool' for a text parameter causes errors.

Forgetting to specify the type.

The 'location' parameter should be of type string because it represents a region name.

Complete the code to define a variable named 'storageAccountName' that concatenates 'storage' and a unique string.

Azure

"variables": {
  "storageAccountName": "concat('storage', [1])"
}

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

Aparameters('location')

BuniqueString(resourceGroup().id)

CresourceGroup().name

Dsubscription().id

💡 Hint

Common Mistakes

Using parameters or subscription ID directly without uniqueness.

Using resourceGroup().name which may not be unique.

The uniqueString(resourceGroup().id) function generates a unique string based on the resource group ID, ensuring the storage account name is unique.

Fix the error in the variable definition that tries to get the first element of a parameter array named 'vmSizes'.

Azure

"variables": {
  "firstVmSize": "[1](parameters('vmSizes'), 0)"
}

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

Aindex

Bfirst

Cparameters

Dparameters('vmSizes')[0]

💡 Hint

Common Mistakes

Using 'first' which is not a valid ARM function.

Trying to use array indexing syntax directly.

The index() function is used in ARM templates to get an element at a specific position from an array.

Fill both blanks to define a parameter 'adminUsername' with a default value and a variable 'adminUser' that references it.

Azure

"parameters": {
  "adminUsername": {
    "type": "[1]",
    "defaultValue": "azureuser"
  }
},
"variables": {
  "adminUser": "[2]('adminUsername')"
}

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

Bint

Cparameters

Dvariables

💡 Hint

Common Mistakes

Using 'int' as parameter type for a username.

Using 'variables' function to reference parameters.

The parameter type should be string. To reference a parameter inside variables, use the parameters() function.

5fill in blank

hard

Fill all three blanks to define a variable 'fullName' that combines 'firstName' and 'lastName' parameters with a space.

Azure

"variables": {
  "fullName": "concat([1]('firstName'), [2], [3]('lastName'))"
}

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

Aparameters

B' '

Dvariables

💡 Hint

Common Mistakes

Using 'variables' function instead of 'parameters'.

Forgetting to add space between names.

Use the parameters() function to get both 'firstName' and 'lastName'. Insert a space string ' ' between them using concat().
