Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a module source.

Terraform

module "network" {
  source = [1]
}

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

A"aws_network"

B"./modules/network"

C"network-module"

D"terraform-network"

💡 Hint

Common Mistakes

Using module names instead of paths for source

Omitting quotes around the source path

The source must be a relative path to the module directory, like "./modules/network".

2fill in blank

medium

Complete the code to pass a variable to a module.

Terraform

module "compute" {
  source = "./modules/compute"
  instance_type = [1]
}

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

At2_micro

Bt2.micro

C"t2.micro"

Dt2micro

💡 Hint

Common Mistakes

Not using quotes around string values

Using underscores instead of dots in instance type

Variable values must be strings enclosed in quotes, like "t2.micro".

3fill in blank

hard

Fix the error in the module output reference.

Terraform

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

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

AsubnetId

Bsubnetid

CsubnetID

Dsubnet_id

💡 Hint

Common Mistakes

Using camelCase or PascalCase instead of snake_case

Mismatching output names with module definitions

Terraform output names are case-sensitive and usually snake_case, so subnet_id is correct.

4fill in blank

hard

Fill both blanks to define a module with variables and outputs correctly.

Terraform

module "storage" {
  source = [1]
  bucket_name = [2]
}

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

A"./modules/storage"

B"storage-bucket"

C"bucket-storage"

D"./modules/bucket"

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing module source with bucket name

Not quoting string values

The source should be the module path "./modules/storage" and bucket_name a string like "storage-bucket".

5fill in blank

hard

Fill all three blanks to output a module's attribute with correct syntax.

Terraform

output "db_endpoint" {
  value = module.[1].[2]_[3]
}

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

Adatabase

Bendpoint

Curl

Ddb

💡 Hint

Common Mistakes

Using wrong module name

Mixing up attribute parts or missing underscores

The module name is 'database', and the output attribute is 'db_endpoint' combining 'db' and 'endpoint'.
