💡 Hint

Common Mistakes

Using incorrect source format like just the module name.

Forgetting to include the provider in the source.

The source attribute specifies the module location. For Terraform Registry modules, it uses the format "namespace/module/provider".

Complete the code to specify the version of the Terraform Registry module.

Terraform

module "my_vpc" {
  source  = "terraform-aws-modules/vpc/aws"
  version = [1]
}

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

A"3.14.0"

💡 Hint

Common Mistakes

Using a number without quotes for version.

Using invalid version strings like "latest".

The version attribute must be a string specifying the exact module version, like "3.14.0".

Fix the error in the module block to correctly pass the VPC CIDR block.

Terraform

module "my_vpc" {
  source     = "terraform-aws-modules/vpc/aws"
  version    = "3.14.0"
  [1] = "10.0.0.0/16"
}

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

💡 Hint

Common Mistakes

Using camelCase or incorrect variable names.

Using partial or abbreviated variable names.

The correct variable name to pass is cidr, matching the module's expected input.

Fill both blanks to define a module with source and enable DNS support.

Terraform

module "my_vpc" {
  source          = [1]
  enable_dns_hostnames = [2]
}

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

Btrue

Cfalse

D"true"

💡 Hint

Common Mistakes

Quoting boolean values like "true".

Using incorrect source strings.

The source must be the module path string, and enable_dns_hostnames is a boolean true or false, not a string.

5fill in blank

hard

Fill all three blanks to define a module with source, version, and enable public subnets.

Terraform

module "my_vpc" {
  source        = [1]
  version       = [2]
  public_subnets = [3]
}

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

A"terraform-aws-modules/vpc/aws"

B"3.14.0"

C["10.0.1.0/24", "10.0.2.0/24"]

Dtrue

Attempts:

💡 Hint

Common Mistakes

Using unquoted version numbers.

Passing booleans instead of lists for subnets.

Incorrect source strings.

The source is the module path string, version is a string with the version number, and public_subnets is a list of subnet CIDR blocks.
