Terraform-Associate-003 Exam Dumps - HashiCorp Certified: Terraform Associate (003) (HCTA0-003)

Detailed Explanation:

Rationale for Correct Answer:Parent modules cannot directly access child module variables. Only values explicitly exposed via outputs can be accessed by the parent module.

Analysis of Incorrect Options (Distractors):

A. True: Incorrect because module variable scope is isolated.

Key Concept:Terraform enforces module encapsulation, exposing data only through outputs.

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 .

From the Terraform Provider Requirements:

">= 3.0" means any versiongreater than or equal to 3.0— including 4.x and beyond.

A (wrong): Would need >= 3.0, < 4.0

C/D (wrong): > excludes 3.0 — not what’s written.

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

The best way to automatically and proactively enforce the security control that new AWS S3 buckets must be private and encrypted at rest is with a Sentinel policy, which runs before every apply. Sentinel is a policy as code framework that allows you to define and enforce logic-based policies for your infrastructure. Terraform Cloud supports Sentinel policies for all paid tiers, and can run them before any terraform plan or terraform apply operation. You can write a Sentinel policy that checks the configuration of the S3 buckets and ensures that they have the proper settings for privacy and encryption, and then assign the policy to your Terraform Cloud organization or workspace. This way, Terraform Cloud will prevent any changes that violate the policy from being applied. References = [Sentinel Policy Framework], [Manage Policies in Terraform Cloud], [Write and Test Sentinel Policies for Terraform]

This is the command that always causes a state file to be updated with changes that might have been made outside of Terraform, as it will only refresh the state file with the current status of the real resources, without making any changes to them or creating a plan.

This is one disadvantage of using dynamic blocks in Terraform, as they can introduce complexity and reduce readability of the configuration. The other options are either advantages or incorrect statements.
