Terraform-Associate-003 Exam Dumps - HashiCorp Terraform Associate Questions and Answers

Detailed Explanation:

Rationale for Correct Answer (B):Terraform uses a state file to map real-world resources to your configuration. By default, if no backend is explicitly defined, Terraform stores this information in a file named terraform.tfstate located in the same directory as your configuration files. This local state file is critical for Terraform to understand what infrastructure already exists and to plan updates correctly.

Analysis of Incorrect Options (Distractors):

A. .terraform.d (home directory subdirectory):This is used for storing plugins and some global settings, not for resource state.

C. .terraform.lock.hcl (lock file):This file locks provider versions to ensure reproducible runs, but it does not contain resource state information.

D. .terraform (subdirectory):This folder contains cached provider binaries and related data, but not the actual state file.

Key Concept:Terraform state management is at the core of "Implement and Maintain State." Understanding where Terraform stores the state by default is critical because state files should often be stored remotely (using a backend like S3, GCS, or Terraform Cloud) for collaboration and reliability.

A module can declare a variable with a default value without requiring the caller to define it. This allows the module to provide a sensible default behavior that can be customized by the caller if needed. References = [Module Variables]

All of the statements are true of Terraform providers. Terraform providers are plugins that enable Terraform to interact with various APIs and services1. Anyone can write a Terraform provider, either as an individual or as part of a community2. HashiCorp maintains some providers, such as the AWS, Azure, and Google Cloud providers3. Cloud providers and infrastructure vendors can also write, maintain, or collaborate on Terraform providers, such as the VMware, Oracle, and Alibaba Cloud providers. References =

The terraform state show command allows you to access all of the attributes and details of a resource managed by Terraform. You can use the resource address (e.g. provider_type.name) as an argument to show the information about a specific resource. The terraform state list command only shows the list of resources in the state, not their attributes. The terraform get command downloads and installs modules needed for the configuration. It does not show any information about resources. References = [Command: state show] and [Command: state list]

This is the Terraform style convention for indenting a nesting level compared to the one above it. The other options are not consistent with the Terraform style guide.

Terraform follows adeclarativeapproach, meaning it ensures the infrastructure matches the configuration.

If you run terraform apply againwithout any changes, Terraform willdetect that the infrastructure is already up to dateand willdo nothing.

The command will complete successfully with the message"No changes. Your infrastructure matches the configuration."

The terraform import command is not part of any other Terraform workflow. It must be explicitly invoked by the user with the appropriate arguments, such as the resource address and the ID of the existing infrastructure to import. References = [Importing Infrastructure]

This is the variable type that you could use for this input, as it can store multiple attributes of different types within a single value. The other options are either invalid or incorrect for this use case.

The public Terraform Module Registry is free to use, as it is a public service that hosts thousands of self-contained packages called modules that are used to provision infrastructure. You can browse, use, and publish modules to the registry without any cost.

The two steps that are required to provision new infrastructure in the Terraform workflow are init and apply. The terraform init command initializes a working directory containing Terraform configuration files. It downloads and installs the provider plugins that are needed for the configuration, and prepares the backend for storing the state. The terraform apply command applies the changes required to reach the desired state of the configuration, as described by the resource definitions in the configuration files. It shows a plan of the proposed changes and asks for confirmation before making any changes to the infrastructure. References = [The Core Terraform Workflow], [Initialize a Terraform working directory with init], [Apply Terraform Configuration with apply]
