HashiCorp TERRAFORM-ASSOCIATE-003 Online Questions & Answers

• Question 391:

  In order to make a Terraform configuration file dynamic and/or reusable, static values should be converted to use what?

  A. Input Parameters
  B. Module
  C. Regular Expressions
  D. Output Value
  A. Input Parameters

  ---

  Explanation

  Input variables serve as parameters for a Terraform module, allowing aspects of the module to be customized without altering the module's own source code, and allowing modules to be shared between different configurations. https:// www.terraform.io/docs/configuration/variables.html

• Question 392:

  Which backend does the Terraform CLI use by default?

  A. Terraform Cloud
  B. Consul
  C. Remote
  D. Local
  D. Local

  ---

  Explanation

  "By default, Terraform implicitly uses a backend called local to store state as a local file on disk. Every other backend stores state in a remote service of some kind, which allows multiple people to access it. Accessing state in a remote service generally requires some kind of access credentials, since state data contains extremely sensitive information." https://www.terraform.io/language/settings/backends

• Question 393:

  Which two steps are required to provision new infrastructure in the Terraform workflow? (Choose two.)

  A. Destroy
  B. Apply
  C. Import
  D. Init
  E. Validate
  B. Apply
  D. Init

  ---

  Explanation

  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.

• Question 394:

  Multiple configurations for the same provider can be used in a single configuration file.

  A. False
  B. True
  B. True

  ---

  Explanation

  You can optionally define multiple configurations for the same provider, and select which one to use on a per-resource or per-module basis. The primary reason for this is to support multiple regions for a cloud platform; other examples include

  targeting multiple Docker hosts, multiple Consul hosts, etc.

  To include multiple configurations for a given provider, include multiple provider blocks with the same provider name, but set the alias meta-argument to an alias name to use for each additional configuration. For example:

  # The default provider configuration

  provider "aws" {

  region = "us-east-1"

  }

  # Additional provider configuration for west coast region provider "aws" {

  alias = "west"

  region = "us-west-2"

  }

  The provider block without alias set is known as the default provider configuration. When alias is set, it creates an additional provider configuration. For providers that have no required configuration arguments, the implied empty configuration

  is considered to be the default provider configuration.

• Question 395:

  When should you write Terraform configuration files for existing infrastructure that you want to start managing with Terraform?

  A. You can import infrastructure without corresponding Terraform code
  B. Terraform will generate the corresponding configuration files for you
  C. Before you run terraform Import
  D. After you run terraform import
  C. Before you run terraform Import

  ---

  Explanation

  You need to write Terraform configuration files for the existing infrastructure that you want to import into Terraform, otherwise Terraform will not know how to manage it. The configuration files should match the type and name of the resources that you want to import.

• Question 396:

  Running terraform fmt without any flags in a directory with Terraform configuration files check the formatting of those files without changing their contents.

  A. True
  B. False
  B. False

  ---

  Explanation

  Running terraform fmt without any flags in a directory with Terraform configuration files will not check the formatting of those files without changing their contents, but will actually rewrite them to a canonical format and style. If you want to check the formatting without making changes, you need to use the -check flag.

• Question 397:

  What is the name of the default file where Terraform stores the state?

  Type your answer in the field provided. The text field is not case-sensitive and all variations of the correct answer are accepted.

  A. terraform.tfstate
  B. PlaceHolder
  C. PlaceHolder
  D. PlaceHolder
  A. terraform.tfstate

  ---

  Explanation

  terraform.tfstate

  The name of the default file where Terraform stores the state is terraform.tfstate. This file contains a JSON representation of the current state of the infrastructure managed by Terraform. Terraform uses this file to track the metadata and

  attributes of the resources, and to plan and apply changes. By default, Terraform stores the state file locally in the same directory as the configuration files, but it can also be configured to store the state remotely in a backend.

• Question 398:

  In Terraform HCL, an object type of object({name=string, age-number}) would match this value.

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  ---

  Explanation

  The name (string) must be written in quotes. The age (number) should not be in quotes and must be written with numeric characters

• Question 399:

  You have recently started a new job at a retailer as an engineer. As part of this new role, you have been tasked with evaluating multiple outages that occurred during peak shopping time during the holiday season. Your investigation found that the team is manually deploying new compute instances and configuring each compute instance manually. This has led to inconsistent configuration between each compute instance.

  How would you solve this using infrastructure as code?

  A. Implement a ticketing workflow that makes engineers submit a ticket before manually provisioning and configuring a resource
  B. Implement a checklist that engineers can follow when configuring compute instances
  C. Replace the compute instance type with a larger version to reduce the number of required deployments
  D. Implement a provisioning pipeline that deploys infrastructure configurations committed to your version control system following code reviews
  D. Implement a provisioning pipeline that deploys infrastructure configurations committed to your version control system following code reviews

• Question 400:

  Anyone can publish and share modules on the Terraform Public Module Registry, and meeting the requirements for publishing a module is extremely easy. Select from the following list all valid requirements. (select three)

  A. The module must be PCI/HIPPA compliant.
  B. Module repositories must use this three-part name format, terraform--.
  C. The registry uses tags to identify module versions.
  D. Release tag names must be for the format x.y.z, and can optionally be prefixed with a v .
  E. The module must be on GitHub and must be a public repo.
  C. The registry uses tags to identify module versions.
  D. Release tag names must be for the format x.y.z, and can optionally be prefixed with a v .
  E. The module must be on GitHub and must be a public repo.
