HashiCorp Updated Terraform-Associate-004 Exam Questions and Answers by ezra

This is not a valid Terraform variable type. The other options are valid variable types that can store different kinds of values2.

The terraform plan command does not update the state file. Instead, it reads the current state and the configuration files to determine what changes would be made to bring the real-world infrastructure into the desired state defined in the configuration. The plan operation is a read-only operation and does not modify the state or the infrastructure. It is the terraform apply command that actually applies changes and updates the state file.References = Terraform ' s official guidelines and documentation clarify the purpose of the terraform plan command, highlighting its role in preparing and showing an execution plan without making any changes to the actual state or infrastructure .

Changing the Terraform backend after performing the initial terraform apply is technically possible but strongly discouraged. This is because changing backends can lead to complexities in state management, requiring manual intervention such as state migration to ensure consistency. Terraform ' s documentation and best practices advise planning the backend configuration carefully before applying Terraform configurations to avoid such changes.References = This guidance is consistent with Terraform ' s official documentation, which recommends careful consideration and planning of backend configurations to avoid the need for changes.

Rationale for Correct Answer: terraform plan -refresh-only refreshes (reconciles) the state with the real infrastructure only for the purpose of the plan output. It does not persist (write) those updates to the state file. To actually update the stored state, you must run terraform apply -refresh-only (or a normal terraform apply). This matches the Terraform CLI objective: plan previews changes; apply makes changes (including writing state).

Analysis of Incorrect Options (Distractors):

A (True): Incorrect because terraform plan does not write state; it only calculates and displays what would change.

Key Concept: The plan vs apply workflow and when Terraform writes state.
