Fill both blanks to correctly name Terraform files for provider and backend configuration.

Terraform

# Provider configuration
provider "aws" {
  region = "us-west-2"
}

# Save this in [1]

# Backend configuration
terraform {
  backend "s3" {
    bucket = "mybucket"
    key    = "path/to/my/key"
    region = "us-west-2"
  }
}

# Save this in [2]

💡 Hint

Common Mistakes

Using .txt extension for Terraform configuration files.

Mixing up provider and backend file names.

Provider configurations are usually saved in provider.tf and backend configurations in backend.tf, both using the .tf extension.

5fill in blank

hard

Fill all three blanks to correctly name Terraform files for main configuration, variables, and outputs.

Terraform

# Main configuration
resource "aws_s3_bucket" "bucket" {
  bucket = "my-tf-bucket"
  acl    = "private"
}

# Save this in [1]

# Variables
variable "bucket_name" {
  type = string
}

# Save this in [2]

# Outputs
output "bucket_id" {
  value = aws_s3_bucket.bucket.id
}

# Save this in [3]
