Practice - 5 Tasks

1fill in blank

easy

Complete the code to declare a variable in a Terraform configuration.

💡 Hint

Common Mistakes

Using integer or bool types for text values.

Leaving the type undefined.

The type of a variable defines what kind of value it holds. For project IDs, string is the correct type.

2fill in blank

medium

Complete the code to output the project ID variable value.

GCP

output "project_id_output" {
  value = [1]
}

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

Aproject_id

Bvar.project_name

Coutput.project_id

Dvar.project_id

💡 Hint

Common Mistakes

Using the output name instead of the variable name.

Omitting the var. prefix.

To output a variable's value, use var.variable_name. Here, var.project_id accesses the project ID variable.

3fill in blank

hard

Fix the error in the output block to correctly reference the variable.

GCP

output "region_output" {
  value = [1]
}

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

Avar.region

Bvar.region_name

Coutput.region

Dregion

💡 Hint

Common Mistakes

Referencing variables without the var. prefix.

Using incorrect variable names.

The correct way to reference a variable in Terraform output is with var.variable_name. Here, var.region is correct.

4fill in blank

hard

Fill both blanks to declare a variable with a default value and output it.

GCP

variable "region" {
  type    = [1]
  default = [2]
}

output "region_output" {
  value = var.region
}

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

Astring

B"us-central1"

Cus-central1

Dinteger

💡 Hint

Common Mistakes

Not quoting the default string value.

Using wrong type for the variable.

The variable type should be string. The default value must be a quoted string like "us-central1" to be valid.

5fill in blank

hard

Fill all three blanks to declare a variable, assign a default, and output its uppercase value.

GCP

variable "env" {
  type    = [1]
  default = [2]
}

output "env_upper" {
  value = upper([3])
}

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

Astring

B"prod"

Cvar.env

Dprod

Attempts:

3 left

💡 Hint

Common Mistakes

Not quoting the default string.

Using the variable name without var. prefix.

Using unquoted strings in output.

The variable type is string. The default value must be a quoted string "prod". To output the uppercase value, use upper(var.env).
