💡 Hint

Common Mistakes

Using generic names like 'ip' or 'address' that may not exist.

Assuming the output name without checking the module.

The module must have an output named public_ip to expose the public IP address.

Fix the error in the output block to correctly reference the module's subnet ID.

Terraform

output "subnet_id" {
  value = module.vpc.[1]

💡 Hint

Common Mistakes

Using camelCase or PascalCase instead of snake_case.

Guessing output names without verifying.

Terraform output names are case-sensitive and usually use snake_case. The correct attribute is subnet_id.

Fill both blanks to output the module's database endpoint and port.

Terraform

output "db_connection" {
  value = "${module.database.[1]:${module.database.[2]"
}

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

💡 Hint

Common Mistakes

Mixing up host and port names.

Using incorrect output names like 'address' or 'host' if not defined.

The database endpoint is usually named endpoint and the port is port in module outputs.

5fill in blank

Fill all three blanks to output a formatted string with module's name, instance ID, and availability zone.

Terraform

  value = "Name: ${module.app.[1], ID: ${module.app.[2], AZ: ${module.app.[3]"
}

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

💡 Hint

Common Mistakes

Confusing instance_id with id.

Using incorrect output names or wrong casing.

The module outputs the instance name as name, the instance ID as id, and the availability zone as availability_zone.
