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

Infrastructure as Code (IaC) refers to managing infrastructureprogrammatically, enabling automation and repeatability.

Ais incorrect becauseIaC is not just about software delivery pipelines; it specifically deals with infrastructure.

Bis incorrect because"Write once, run anywhere" applies more to software development than IaC.

Dis incorrect becauseIaC does not enforce vendor-agnostic APIs; it depends on the tool and provider.

What is Infrastructure as Code?

Terraform modules are referenced by specifying a source location. This location can be a URL or a file path. However, specifying query parameters such as ?version=vl.6.0 directly within the source path is not a valid or supported method for specifying a module version in Terraform. Instead, version constraints are specified using the version argument within the module block, not as part of the source string.References = This clarification is based on Terraform's official documentation regarding module usage, which outlines the correct methods for specifying module sources and versions.

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.

The .terraform.lock.hcl file is a new feature in Terraform 0.14 that records the exact versions of each provider used in your configuration. This helps ensure consistent and reproducible behavior across different machines and runs.

Terraform Cloud provides features like remote state storage and a web-based user interface for managing your Terraform runs. While it offers robust infrastructure as code capabilities, automatic backups of configuration and state are not directly provided by Terraform Cloud; instead, the state is stored remotely and secured.

You can install third party plugins using terraform init, as long as you specify the plugin directory in your configuration or as a command-line argument. You can also use the terraform providers mirror command to create a local mirror of providers from any source.

Speculative Plans: Terraform Cloud’sspeculative planfeature runs automatically when changes are detected in a linked VCS repository, enabling users to review potential infrastructure changes without committing them.

Automatic Integration: This feature automates the planning process by triggering when changes are committed, aiding teams in previewing infrastructure changes seamlessly.

For further understanding, see theTerraform Cloud VCS Integrationdocumentation.

This is a secure way to inject sensitive variables into your Terraform run, as they will not be stored in any file or source code repository. You can also use environment variables or variable files with encryption to pass sensitive variables to Terraform.

Sentinel is a policy-as-code framework that allows you to define and enforce rules on your Terraform configurations, states, and plans1. Some of the benefits of using Sentinel with Terraform Cloud/Terraform Enterprise are:

•You can restrict specific resource configurations, such as disallowing the use of CIDR=0.0.0.0/0, which would open up your network to the entire internet. This can help you prevent misconfigurations or security vulnerabilities in your infrastructure2.

•Policy-as-code can enforce security best practices, such as requiring encryption, authentication, or compliance standards. This can help you protect your data and meet regulatory requirements3.

•You can enforce a list of approved AWS AMIs, which are pre-configured images that contain the operating system and software you need to run your applications. This can help you ensure consistency, reliability, and performance across your infrastructure4.

Terraform detects infrastructure drift by comparing thestate filewith the actual infrastructure.

When an instance ismanually deleted, Terraformsees it as missingand marks it for recreation.

Running terraform apply willonly recreate the missing instanceswhile leaving the rest of the infrastructure unchanged.

Explanation of incorrect answers:

A (Tear down everything and rebuild)– Incorrect. Terraform does not destroy existing infrastructure unless explicitly told to.

B (Build a completely new set of infrastructure)– Incorrect. Terraform does not create duplicates unless configuration changes.

D (Stop and error out)– Incorrect. Terraform does not fail; itrebuilds missing resourcesautomatically.
