Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a Terraform module source path.

  source = "[1]"
}

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

Aterraform-example

Bexample-module

C./modules/example

D/modules/example

💡 Hint

Common Mistakes

Using just the module name without a path.

Starting the path with a slash which makes it absolute instead of relative.

The source attribute in a Terraform module block specifies the relative path to the module folder. Using ./modules/example correctly points to a local module.

Complete the code to declare a variable inside a Terraform module.

Terraform

variable "region" {
  type    = string
  default = "[1]"
}

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

Aus-east-1

Bregion-1

Cdefault-region

Dus-west-2

💡 Hint

Common Mistakes

Using invalid or placeholder strings that are not real regions.

Leaving the default empty or missing.

The default value for a variable sets the default region. us-east-1 is a common AWS region example.

3fill in blank

hard

Fix the error in the module output declaration.

Terraform

output "instance_id" {
  value = [1]
}

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

Aexample.id

Baws_instance.example

Cinstance.id

Daws_instance.example.id

💡 Hint

Common Mistakes

Referencing the resource without the attribute.

Using incomplete or incorrect resource names.

The output value must reference the resource attribute correctly. aws_instance.example.id accesses the instance ID attribute.

4fill in blank

hard

Fill both blanks to create a module call with a variable and output.

Terraform

module "web_server" {
  source = "[1]"
  region = var.[2]
}

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

A./modules/webserver

Bregion

Cwebserver

D./webserver

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect source paths.

Passing variables without the var. prefix.

The source should point to the local module folder ./modules/webserver. The variable region is passed from var.region.

5fill in blank

hard

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

Terraform

module "db" {
  source = "[1]"
  db_name = var.[2]
  db_port = var.[3]
}

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

A./modules/database

Bname

Cport

D./database

Attempts:

💡 Hint

Common Mistakes

Using incorrect source paths.

Mismatching variable names between module and call.

The module source is ./modules/database. Variables db_name and db_port are passed from var.name and var.port respectively.
