easy

Complete the code to call a child module named 'network'.

  source = [1]
}

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

A"../network"

B"network-module"

C"./modules/network"

D"network"

💡 Hint

Common Mistakes

Using just the module name without a path.

Using a relative path that does not exist.

The source attribute specifies the path to the child module directory. Using "./modules/network" correctly points to the child module folder.

Complete the code to pass a variable 'region' with value 'us-west-1' to the child module.

Terraform

module "network" {
  source = "./modules/network"
  [1] = "us-west-1"
}

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

💡 Hint

Common Mistakes

Using a wrong variable name like 'location' or 'zone'.

Forgetting to pass the variable at all.

The variable name must match the input variable defined in the child module. Here, region is the correct variable to pass.

Fix the error in the child module call by completing the missing attribute to output the module's VPC ID.

Terraform

output "vpc_id" {
  value = module.network.[1]
}

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

Avpcid

BvpcId

CvpcID

Dvpc_id

💡 Hint

Common Mistakes

Using camelCase or incorrect casing.

Using a name not defined in the child module outputs.

The output attribute must exactly match the output name defined in the child module, which is vpc_id in snake_case.

4fill in blank

hard

Fill both blanks to define a child module with source path and pass a variable 'cidr_block'.

Terraform

module "vpc" {
  source = [1]
  [2] = "10.0.0.0/16"
}

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

A"./modules/vpc"

Bcidr_block

Cvpc_cidr

D"vpc-module"

Attempts:

💡 Hint

Common Mistakes

Using an incorrect source path.

Using a wrong variable name like 'vpc_cidr'.

The source must point to the child module folder "./modules/vpc". The variable name cidr_block matches the expected input variable in the child module.

5fill in blank

hard

Fill all three blanks to define a child module, pass variables 'name' and 'environment', and output the module's subnet ID.

Terraform

module "subnet" {
  source      = [1]
  name        = [2]
  environment = [3]
}

output "subnet_id" {
  value = module.subnet.subnet_id
}

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

A"./modules/subnet"

B"prod-subnet"

C"production"

D"./subnet-module"

💡 Hint

Common Mistakes

Using incorrect source paths.

Passing variables without quotes.

Using inconsistent variable names.

The source points to the child module folder "./modules/subnet". The variables name and environment are passed with appropriate string values matching typical naming conventions.
