1fill in blank

easy

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

💡 Hint

Common Mistakes

Using 'latest' as a version string

Omitting quotes around the version number

The version attribute specifies the exact module version to use, such as "3.0.0".

medium

Complete the code to pin the module version to a specific release.

Terraform

module "storage" {
  source  = "terraform-aws-modules/s3-bucket/aws"
  version = "[1]"
}

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

A"latest"

B">= 1.0.0"

C"~> 2.5.0"

D"2"

💡 Hint

Common Mistakes

Using 'latest' which is invalid

Using only a major version without constraint operator

The ~> 2.5.0 syntax pins the module to versions compatible with 2.5.x, allowing patch updates.

Fix the error in the module version specification.

Terraform

module "compute" {
  source  = "terraform-aws-modules/ec2-instance/aws"
  version = [1]
}

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

A"1.4.0"

B1.4.0

C"latest"

Dlatest

💡 Hint

Common Mistakes

Not quoting the version string

Using 'latest' without quotes

The version must be a quoted string. Unquoted or using 'latest' without quotes causes errors.

4fill in blank

hard

Fill both blanks to specify a module with a version constraint and a source registry.

Terraform

module "database" {
  source  = "[1]"
  version = "[2]"
}

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

Aterraform-aws-modules/rds/aws

B1.0.0

C~> 3.2.1

Daws-modules/rds

💡 Hint

Common Mistakes

Using incomplete source paths

Using exact version instead of constraint

The source must be the full registry path like terraform-aws-modules/rds/aws, and the version constraint uses ~> for patch updates.

5fill in blank

hard

Fill all three blanks to define a module with a Git source and a specific ref version.

Terraform

module "app" {
  source = "git::https://github.com/terraform-modules/app.git?ref=[1]"
  version = "[2]"
  providers = { aws = [3] }
}

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

Av1.2.3

B1.2.3

Caws.default

Daws.main

Attempts:

3 left

💡 Hint

Common Mistakes

Omitting 'v' in the Git ref

Using wrong provider alias

The ref in the Git URL pins the module to tag v1.2.3. The version is a string matching the tag without 'v'. The provider alias is aws.default.
