   A root configuration includes a module that creates an AWS S3 bucket and outputs the bucket ARN. A separate resource creates an S3 bucket policy that references the bucket ARN. The developer writes: resource "aws_s3_bucket_policy" "policy" { bucket = module.bucket.bucket_arn policy = "..." } What is the execution order?

   • ATerraform fails because the output reference is invalid.
   • BThe bucket policy resource is applied before the module.
   • CBoth are applied in parallel.
   • DThe S3 bucket module is applied before the bucket policy resource.

   A root configuration includes two modules: one creates an AWS VPC and outputs the VPC ID, and the other creates a subnet and needs the VPC ID. The subnet module also outputs the subnet ID, which is used by a separate resource in the root configuration. How does Terraform determine the execution order?

   • AAll three are applied in parallel because they are in different modules.
   • BThe VPC module is applied first, then the subnet module, then the resource that uses the subnet ID.
   • CThe subnet module is applied first because it outputs the subnet ID.
   • DThe resource that uses the subnet ID is applied first because it is in the root configuration.

   A team uses a module from the Terraform Registry to create Google Cloud Pub/Sub topics. They have been using version 1.0.0. They want to upgrade to the latest 1.x version but are worried about a potential 2.0 release. They also want to ensure that any future 1.x version is acceptable. Which version constraint should they use?

   • Aversion = "~> 1.0"
   • Bversion = ">= 1.0.0"
   • Cversion = "~> 1.0.0"
   • Dversion = "1.0.0"

   A root configuration includes a module that creates an Azure App Service plan and outputs its ID. A separate resource creates an App Service and needs the plan ID. The developer writes: resource "azurerm_app_service" "app" { name = "myapp" location = "East US" resource_group_name = "rg" app_service_plan_id = module.app_service_plan.plan_id } What is the execution order?

   • ABoth are applied in parallel.
   • BTerraform fails because the output reference is invalid.
   • CThe App Service resource is applied before the module.
   • DThe App Service plan module is applied before the App Service resource.
