Runningterraform destroywill show all resources that will be deleted before prompting for approval. You can also runterraform plan -destroyto simulate the destruction without actually applying it, which is useful for reviewing the planned changes.

The terraform init command is required before using a new backend or integrating with HCP Terraform/Terraform Cloud.

terraform init initializes the working directory and sets up the backend, downloading necessary provider plugins and modules.

If the backend configuration changes, Terraform willrequirere-initialization to apply those changes.

Without running terraform init, Terraform willfailto use a new backend or remote Terraform Cloud workspace.

A Terraformbackenddetermineswhere and how Terraform state is stored.

Bothterraform applyandterraform destroyinteract with state, so Terraform needs access to the backend for state storage and updates.

D (Neither are correct)is incorrect becauseTerraform state is required for both apply and destroy operations.

Terraform Backends

The Terraform Registry allows any user to publish and share modules. Published modules support versioning, automatically generate documentation, allow browsing version histories, show examples and READMEs, and more. Public modules are managed via Git and GitHub, and publishing a module takes only a few minutes. Once a module is published, releasing a new version of a module is as simple as pushing a properly formed Git tag1.

Not all standard backend types support state locking and remote operations like plan, apply, and destroy. For example, the local backend does not support remote operations and state locking. State locking is a feature that ensures that no two users can make changes to the state file at the same time, which is crucial for preventing race conditions. Remote operations allow running Terraform commands on a remote server, which is supported by some backends like remote or consul, but not all.

It is not a best practice to store secret data in the same version control repository as your Terraform configuration, as it could expose your sensitive information to unauthorized parties or compromise your security. You should use environment variables, vaults, or other mechanisms to store and provide secret data to Terraform.

You can configure a backend in your Terraform code before initializing it. Initializing a backend will store the state file remotely and enable features like locking and workspaces. References = [Terraform Backends]
