Pass the HashiCorp Terraform Associate Terraform-Associate-003 Questions and answers with CertsForce

When you use a remote backend that needs authentication, HashiCorp recommends that you:

Importing Existing Resources: Theterraform importcommand brings resources already deployed in a cloud environment into Terraform’s state file, allowing Terraform to manage them.

Workflow Usage: Importing is vital when managing resources created outside of Terraform or those in place before Terraform adoption.

Refer to Terraform’s import command documentation.

This command will initialize the new backend and prompt you to migrate the existing state file to the new location4. The other commands are not relevant for this task.

This command will initialize the new backend and prompt you to migrate the existing state file to the new location3. The other commands are not relevant for this task.

In Terraform, the backend configuration, which includes details about where and how state is stored, is specified within the terraform block of your configuration. This block is the correct place to define the backend type and its configuration parameters, such as the location of the state file for a local backend or the bucket details for a remote backend like S3.References = This practice is outlined in Terraform's core documentation, which provides examples and guidelines on how to configure various aspects of Terraform's behavior, including state backends .

Purpose of Refresh-Only Mode: Running Terraform inrefresh-only modeupdates Terraform's state file with the current state of resources in your infrastructure without making changes to the resources themselves.

Context of Terraform Import: When usingterraform import, you’re adding existing resources to the state file, and running Terraform in refresh-only mode before this operation can ensure that any initial configuration syncs precisely with the actual state.

For more on refresh-only mode in relation to terraform import, refer to Terraform's import documentation.

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

This will trigger a run in the Terraform Cloud workspace, which will perform a plan and apply operation on the infrastructure defined by the Terraform configuration files in the VCS repository.

Infrastructure as code (IaC) is a way of managing and provisioning cloud infrastructure using programming techniques instead of manual processes1. IaC has many advantages over using a graphical user interface (GUI) for provisioning infrastructure, such as:

•Versioning: IaC allows you to store your infrastructure configuration in a version control system, such as Git, and track changes over time. This enables you to roll back to previous versions, compare differences, and collaborate with other developers2.

•Reusability: IaC allows you to create reusable modules and templates that can be applied to different environments, such as development, testing, and production. This reduces duplication, improves consistency, and speeds up deployment3.

•Sharing: IaC allows you to share your infrastructure configuration with other developers, teams, or organizations, and leverage existing code from open source repositories or registries. This fosters best practices, innovation, and standardization4.

•Risk reduction: IaC reduces the risk of human error, configuration drift, and security breaches that can occur when provisioning infrastructure manually or using a GUI. IaC also enables you to perform automated testing, validation, and compliance checks on your infrastructure before deploying it5.

You should run terraform init after you start coding a new Terraform project and before you run terraform plan for the first time. This command will initialize the working directory by downloading the required providers and modules, creating the initial state file, and performing other necessary tasks. References = : Initialize a Terraform Project
