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

Referencing Terraform Built-in Functions:

✅chomp: removes trailing newlines

✅join: combines list into string

✅split: splits string into list

❌slice:is nota valid Terraform string function (it ' s used in other languages like Python)

Rationale for Correct Answer (C):

Version constraints must be specified with = and quotes, e.g.:

version = " > = 3.1 "

This ensures compatibility with Terraform’s syntax.

Analysis of Incorrect Options:

A, B: Incorrect syntax, missing quotes or wrong operator format.

C: Correct Terraform syntax.

Key Concept:

Correct syntax in provider version constraints ensures reproducibility.

Rationale for Correct Answer: Terraform can store state in a remote backend (remote location) configured in the terraform block (for example, terraform { backend " s3 " { ... } } or terraform { cloud { ... } }). Remote backends store the state outside the local filesystem and often add collaboration features like locking.

Analysis of Incorrect Options (Distractors):

B: Incorrect—CLI configuration files (like .terraformrc / terraform.rc) control CLI behavior (credentials helpers, plugin cache, etc.), but backend/state storage is configured in the Terraform configuration (terraform block) and initialized with terraform init.

C: Incorrect—Terraform must persist state between runs; in-memory storage would be lost when the process ends.

D: Incorrect—environment variables can influence behavior (e.g., credentials, logging), but Terraform does not store state in environment variables.

Key Concept: Configuring remote backends for state storage via the terraform block.

Sentinel policies are checked after the plan stage of a Terraform run, but before it can be confirmed or the terraform apply is executed3. This allows you to enforce rules on your infrastructure before it is created or modified.
