HashiCorp HashiCorp Certifications TERRAFORM-ASSOCIATE-003 Questions & Answers

• Question 51:

  Terraform providers are always installed from the Internet.

  A. True

  B. False

  Correct Answer: B

  Terraform providers are not always installed from the Internet. There are other ways to install provider plugins, such as from a local mirror or cache, from a local filesystem directory, or from a network filesystem. These methods can be useful for offline or air-gapped environments, or for customizing the installation process. You can configure the provider installation methods using the provider_installation block in the CLI configuration file.

• Question 52:

  You want to define a single input variable to capture configuration values for a server. The values must represent memory as a number, and the server name as a string. Which variable type could you use for this input?

  A. List

  B. Object

  C. Map

  D. Terraform does not support complex input variables of different types

  Correct Answer: B

  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.

• Question 53:

  Which command should you run to check if all code in a Terraform configuration that references multiple modules is properly formatted without making changes?

  A. terraform fmt -write-false

  B. terraform fmt -list -recursive

  C. terraform fmt -check -recursive

  D. terraform fmt -check

  Correct Answer: C

  This command will check if all code in a Terraform configuration that references multiple modules is properly formatted without making changes, and will return a non-zero exit code if any files need formatting. The other commands will either make changes, list the files that need formatting, or not check the modules.

• Question 54:

  You have provisioned some virtual machines (VMs) on Google Cloud Platform (GCP) using the gcloud command line tool. However, you are standardizing with Terraform and want to manage these VMs using Terraform instead. What are the two things you must do to achieve this? Choose two correct answers.

  A. Run the terraform Import-gcp command

  B. Write Terraform configuration for the existing VMs

  C. Use the terraform import command for the existing VMs

  D. Provision new VMs using Terraform with the same VM names

  Correct Answer: BC

  To import existing resources into Terraform, you need to do two things1:

  Write a resource configuration block for each resource, matching the type and name used in your state file.

  Run terraform import for each resource, specifying its address and ID. There is no such command as terraform Import-gcp, and provisioning new VMs with the same names will not import them into Terraform.

• Question 55:

  Which of these commands makes your code more human readable?

  A. Terraform validate

  B. Terraform output

  C. Terraform show

  D. Terraform fmt

  Correct Answer: D

  The command that makes your code more human readable is terraform fmt. This command is used to rewrite Terraform configuration files to a canonical format and style, following the Terraform language style conventions and other minor adjustments for readability. The command is optional, opinionated, and has no customization options, but it is recommended to ensure consistency of style across different Terraform codebases. Consistency can help your team understand the code more quickly and easily, making the use of terraform fmt very important. You can run this command on your configuration files before committing them to source control or as part of your CI/CD pipeline.

• Question 56:

  In a Terraform Cloud workpace linked to a version control repository speculative plan rum start automatically commit changes to version control.

  A. True

  B. False

  Correct Answer: A

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

• Question 57:

  What feature stops multiple users from operating on the Terraform state at the same time?

  A. State locking

  B. Version control

  C. Provider constraints

  D. Remote backends

  Correct Answer: A

  State locking prevents other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss1.

• Question 58:

  You add a new provider to your configuration and immediately run terraform apply in the CD using the local backend. Why does the apply fail?

  A. The Terraform CD needs you to log into Terraform Cloud first

  B. Terraform requires you to manually run terraform plan first

  C. Terraform needs to install the necessary plugins first

  D. Terraform needs you to format your code according to best practices first

  Correct Answer: C

  The reason why the apply fails after adding a new provider to the configuration and immediately running terraform apply in the CD using the local backend is because Terraform needs to install the necessary plugins first. Terraform providers are plugins that Terraform uses to interact with various cloud services and other APIs. Each provider has a source address that determines where to download it from. When Terraform encounters a new provider in the configuration, it needs to run terraform init first to install the provider plugins in a local directory. Without the plugins, Terraform cannot communicate with the provider and perform the desired actions. References = [Provider Requirements], [Provider Installation]

• Question 59:

  You want to know from which paths Terraform is loading providers referenced in your Terraform configuration (* files). You need to enable additional logging messages to find this out. Which of the following would achieve this?

  A. Set verbose for each provider in your Terraform configuration

  B. Set the environment variable TF_LOG_TRACE

  C. Set the environment variable TF_LOG_PATH

  D. Set the environment variable TF_log_TRACE

  Correct Answer: B

  This will enable additional logging messages to find out from which paths Terraform is loading providers referenced in your Terraform configuration files, as it will set the log level to TRACE, which is the most verbose and detailed level.

• Question 60:

  Which is the best way to specify a tag of v1.0.0 when referencing a module stored in Git (for example.Git::https://example.com/vpc.git)?

  A. Append pref=v1.0.0 argument to the source path

  B. Add version = "1.0.0" parameter to module block

  C. Nothing modules stored on GitHub always default to version 1.0.0

  Correct Answer: A

  The best way to specify a tag of v1.0.0 when referencing a module stored in Git is to append ?ref=v1.0.0 argument to the source path. This tells Terraform to use a specific Git reference, such as a branch, tag, or commit, when fetching the module source code. For example, source = "git::https://example.com/vpc.git?ref=v1.0.0". This ensures that the module version is consistent and reproducible across different environments. References = [Module Sources], [Module Versions]
