💡 Hint

Common Mistakes

Using boolean or numeric values instead of a region string.

Using an invalid region name.

The region argument expects a valid AWS region string like us-west-2.

Complete the code to set the instance type argument for the AWS EC2 resource.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "[1]"
}

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

Common Mistakes

Using boolean or numeric values instead of a valid instance type string.

Using an invalid instance type.

The instance_type argument requires a valid EC2 instance type string like t2.micro.

Fix the error in the expression to correctly reference the variable 'environment'.

Terraform

variable "environment" {
  type = string
}

resource "aws_s3_bucket" "bucket" {
  bucket = "my-app-[1]"
  acl    = "private"
}

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

D${var.environment}

💡 Hint

Common Mistakes

Using variable name without interpolation syntax.

Using interpolation without the 'var.' prefix.

In Terraform, to use a variable inside a string, you must use interpolation syntax like ${var.environment}.

4fill in blank

hard

Fill both blanks to create a map variable with keys 'dev' and 'prod' and their respective CIDR blocks.

Terraform

variable "cidr_blocks" {
  type = map(string)
  default = {
    dev  = "[1]"
    prod = "[2]"
  }
}

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

A"10.0.1.0/24"

B"10.0.0.0/16"

C"10.0.2.0/24"

D"10.0.3.0/24"

Attempts:

💡 Hint

Common Mistakes

Using the same CIDR block for both environments.

Not using quotes around CIDR strings.

The map variable defines CIDR blocks for 'dev' and 'prod'. Here, 'dev' uses '10.0.1.0/24' and 'prod' uses '10.0.2.0/24'.

5fill in blank

hard

Fill all three blanks to create a resource with a tag key 'Name' and value from a variable, and enable versioning.

Terraform

resource "aws_s3_bucket" "example" {
  bucket = "my-bucket"

  tags = {
    Name = [1]
  }

  versioning {
    enabled = [2]
  }

  lifecycle_rule {
    id      = "log"
    enabled = [3]
  }
}

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

A"var.bucket_name"

Btrue

Cfalse

Dvar.bucket_name

Attempts:

3 left

💡 Hint

Common Mistakes

Putting variable references inside quotes, making them literal strings.

Using string 'true' instead of boolean true.

The tag value should be the variable var.bucket_name without quotes to reference it. Versioning and lifecycle rule 'enabled' flags are booleans set to true.
