HashiCorp Updated Terraform-Associate-003 Exam Questions and Answers by zaynah

You can develop a custom provider to manage its resources using Terraform, as Terraform is an extensible tool that allows you to write your own plugins in Go language. You can also publish your custom provider to the Terraform Registry or use it privately.

Detailed Explanation:

Rationale for Correct Answers:

B. View the execution plan: Correct — terraform plan shows what Terraform intends to do (create, update, or destroy).

C. Save a generated execution plan: Correct — using terraform plan -out=planfile lets you save the plan to apply later with terraform apply planfile.

Analysis of Incorrect Options:

A. Schedule runs in the future: Incorrect, Terraform does not provide scheduling; external tools (like cron, CI/CD) are required.

D. Execute a plan in a different workspace: Incorrect, execution happens in the current workspace; switching workspaces must be done before running the plan.

Key Concept:terraform plan is used for previewing and optionally saving an execution plan for controlled and predictable infrastructure changes.

 This is the command that can add existing resources into Terraform state, by matching them with the corresponding configuration blocks in your files. 

This is how Terraform manages most dependencies between resources, by using the references between them in the configuration files. For example, if resource A depends on resource B, Terraform will create resource B first and then pass its attributes to resource A.
