1fill in blank

easy

Complete the code to declare a resource that creates an AWS S3 bucket.

Terraform

resource "aws_s3_bucket" "my_bucket" {
  bucket = [1]
}

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

A"my-unique-bucket-name"

Baws_s3_bucket.my_bucket

💡 Hint

Common Mistakes

Using a data source reference instead of a string for the bucket name.

Omitting quotes around the bucket name.

The resource block creates a new AWS S3 bucket with the specified name. The bucket name must be a string.

2fill in blank

medium

Complete the code to declare a data source that reads an existing AWS S3 bucket.

Terraform

data "aws_s3_bucket" "existing_bucket" {
  bucket = [1]
}

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

💡 Hint

Common Mistakes

Using a resource reference instead of a string for the bucket name.

Forgetting to put quotes around the bucket name.

The data block reads information about an existing AWS S3 bucket. The bucket name must be a string literal.

hard

Fix the error in referencing the bucket name from a data source in the resource block.

Terraform

resource "aws_s3_bucket_policy" "policy" {
  bucket = [1].bucket
  policy = jsonencode({
    Statement = []
  })
}

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

Adata.aws_s3_bucket_policy.existing_policy

Baws_s3_bucket.my_bucket

Caws_s3_bucket_policy.policy

Ddata.aws_s3_bucket.existing_bucket

💡 Hint

Common Mistakes

Referencing a resource instead of a data source.

Using the wrong attribute name.

To reference an existing bucket from a data source, use data.aws_s3_bucket.existing_bucket.bucket. This accesses the bucket attribute from the data source.

4fill in blank

hard

Fill both blanks to create a resource that uses a data source to get the VPC ID.

Terraform

data "aws_vpc" "selected" {
  filter {
    name   = [1]
    values = ["default"]
  }
}

resource "aws_subnet" "example" {
  vpc_id     = [2].id
  cidr_block = "10.0.1.0/24"
}

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

A"tag:Name"

Bdata.aws_vpc.selected

C"vpc-id"

Daws_vpc.default

💡 Hint

Common Mistakes

Using incorrect filter names.

Referencing resources instead of data sources.

The data source filter uses the tag name to find the default VPC. The resource references the data source's ID attribute.

5fill in blank

hard

Fill all three blanks to create a resource that uses a data source to get an AMI ID and launch an EC2 instance.

Terraform

data "aws_ami" "ubuntu" {
  most_recent = true
  filter {
    name   = [1]
    values = ["ubuntu/images/hvm-ssd/ubuntu-focal-20.04-amd64-server-*"]
  }
  owners = [[2]]
}

resource "aws_instance" "web" {
  ami           = [3].id
  instance_type = "t2.micro"
}

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

A"name"

B"099720109477"

Cdata.aws_ami.ubuntu

D"owner-id"

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect filter or owner keys.

Referencing the resource instead of the data source.

The data source filters AMIs by the name attribute. The owner ID is a string. The resource references the data source's ID attribute.
