The remote backend can work with either a single remote Terraform Cloud workspace, or with multiple similarly-named remote workspaces (like networking-dev and networking-prod). The workspaces block of the backend configuration determines which mode it uses. To use a single remote Terraform Cloud workspace, set workspaces.name to the remote workspace’s full name (like networking-prod). To use multiple remote workspaces, set workspaces.prefix to a prefix used in all of the desired remote workspace names. For example, set prefix = “networking-” to use Terraform cloud workspaces with names like networking-dev and networking-prod. This is helpful when mapping multiple Terraform CLI workspaces used in a single Terraform configuration to multiple Terraform Cloud workspaces3. However, one remote backend configuration always maps to a single remote workspace, either by name or by prefix. You cannot use both name and prefix in the same backend configuration, or omit both. Doing so will result in a configuration error3. References = [Backend Type: remote]3

In the given Terraform configuration snippet:

resource " aws_vpc " " main " {

name = " test "

}

The provider for the resource aws_vpc is aws. The provider is specified by the prefix of the resource type. In this case, aws_vpc indicates that the resource type vpc is provided by the aws provider.

The two steps that are required to provision new infrastructure in the Terraform workflow are init and apply. The terraform init command initializes a working directory containing Terraform configuration files. It downloads and installs the provider plugins that are needed for the configuration, and prepares the backend for storing the state. The terraform apply command applies the changes required to reach the desired state of the configuration, as described by the resource definitions in the configuration files. It shows a plan of the proposed changes and asks for confirmation before making any changes to the infrastructure. References = [The Core Terraform Workflow], [Initialize a Terraform working directory with init] , [Apply Terraform Configuration with apply]

Detailed Explanation:

Rationale for Correct Answer: Setting version = " 3.1.4 " pins the module to that exact version, preventing Terraform from selecting any newer version. This is the strongest guard against unexpected changes (including potential breaking changes) because it does not allow upgrades unless you explicitly change the version constraint.

Analysis of Incorrect Options (Distractors):

A: Incorrect. This allows any version < 3.2 (including 3.1.5, 3.1.9, etc.). Those may still introduce behavioral changes you want to avoid.

B: Incorrect. This forces Terraform to use 3.1.5 or newer, the opposite of what you want.

D: Incorrect. ~ > 3.1.4 allows patch-level updates (e.g., 3.1.5, 3.1.9) and could still introduce changes your team wants to avoid.

Key Concept: Module version constraints and pinning to avoid unexpected upgrades.

To see all the resources that Terraform will delete, you can use either of these two commands:

terraform destroy will show the plan of destruction and ask for your confirmation before proceeding. You can cancel the command if you do not want to destroy the resources.

terraform plan -destroy will show the plan of destruction without asking for confirmation. You can use this command to review the changes before running terraform destroy. References = : Destroy Infrastructure : Plan Command: Options

Some backends support state locking, which prevents other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss. Not all backends support this feature, and you can check the documentation for each backend type to see if it does.

This is not a valid Terraform collection type, as Terraform only supports three collection types: list, map, and set. A tree is a data structure that consists of nodes with parent-child relationships, which is not supported by Terraform.

The default “local” Terraform backend stores the state file in a local file named terraform.tfstate, which can be used to track and manage the state of your infrastructure3.

Inrefresh-only mode(terraform apply -refresh-only), Terraformupdates the state fileto match the actual infrastructurewithout modifying resources.

A (Terraform configuration)–Not modifiedin refresh-only mode.

B (Terraform plan)–Plan is generated but not modified.

D (Cloud infrastructure)–Not modifiedin refresh-only mode.

The public Terraform Module Registry is free to use, as it is a public service that hosts thousands of self-contained packages called modules that are used to provision infrastructure. You can browse, use, and publish modules to the registry without any cost.
