HashiCorp HashiCorp Certifications TERRAFORM-ASSOCIATE-003 Questions & Answers

• Question 41:

  What information does the public Terraform Module Registry automatically expose about published modules?

  A. Required input variables

  B. Optional inputs variables and default values

  C. Outputs

  D. All of the above

  E. None of the above

  Correct Answer: D

  The public Terraform Module Registry automatically exposes all the information about published modules, including required input variables, optional input variables and default values, and outputs. This helps users to understand how to use and configure the modules.

• Question 42:

  You are writing a child Terraform module that provisions an AWS instance. You want to reference the IP address returned by the child module in the root configuration. You name the instance resource "main'. Which of these is the correct way to define the output value?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: D

• Question 43:

  When should you run terraform init?

  A. Every time you run terraform apply

  B. Before you start coding a new Terraform project

  C. After you run terraform plan for the time in a new terraform project and before you run terraform apply

  D. After you start coding a new terraform project and before you run terraform plan for the first time.

  Correct Answer: D

  You should run terraform init after you start coding a new Terraform project and before you run terraform plan for the first time. This command will initialize the working directory by downloading the required providers and modules, creating the initial state file, and performing other necessary tasks.

• Question 44:

  If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform Init.

  A. True

  B. False

  Correct Answer: A

  If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform init3. This will ensure that you use the same provider versions across different machines and runs.

• Question 45:

  When using multiple configuration of the same Terraform provider, what meta-argument must you include in any non-default provider configurations?

  A. Alias

  B. Id

  C. Depends_on

  D. name

  Correct Answer: A

  This is the meta-argument that you must include in any non-default provider configurations, as it allows you to give a friendly name to the configuration and reference it in other parts of your code. The other options are either invalid or irrelevant for this purpose.

• Question 46:

  Where does the Terraform local backend store its state?

  A. In the terraform file

  B. In the /tmp directory

  C. In the terraform,tfstate file

  D. In the user's terraform,state file

  Correct Answer: C

  This is where the Terraform local backend stores its state, by default, unless you specify a different file name or location in your configuration. The local backend is the simplest backend type that stores the state file on your local disk.

• Question 47:

  What does state looking accomplish?

  A. Prevent accidental Prevent accident deletion of the state file

  B. Blocks Terraform commands from modifying, the state file

  C. Copies the state file from memory to disk

  D. Encrypts any credentials stored within the state file

  Correct Answer: B

  This is what state locking accomplishes, by preventing other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss.

• Question 48:

  What is a key benefit of the Terraform state file?

  A. A state file can schedule recurring infrastructure tasks

  B. A state file is a source of truth for resources provisioned with Terraform

  C. A state file is a source of truth for resources provisioned with a public cloud console

  D. A state file is the desired state expressed by the Terraform code files

  Correct Answer: B

  This is a key benefit of the Terraform state file, as it stores and tracks the metadata and attributes of the resources that are managed by Terraform, and allows Terraform to compare the current state with the desired state expressed by your configuration files.

• Question 49:

  You have multiple team members collaborating on infrastructure as code (IaC) using Terraform, and want to apply formatting standards for readability. How can you format Terraform HCL (HashiCorp Configuration Language) code according to standard Terraform style convention?

  A. Run the terraform fmt command during the code linting phase of your CI/CD process Most Voted

  B. Designate one person in each team to review and format everyone's code

  C. Manually apply two spaces indentation and align equal sign "=" characters in every Terraform file (*.tf)

  D. Write a shell script to transform Terraform files using tools such as AWK, Python, and sed

  Correct Answer: A

  The terraform fmt command is used to rewrite Terraform configuration files to a canonical format and style. This command applies a subset of the Terraform language style conventions, along with other minor adjustments for readability. Running this command on your configuration files before committing them to source control can help ensure consistency of style between different Terraform codebases, and can also make diffs easier to read. You can also use the -check and -diff options to check if the files are formatted and display the formatting changes respectively2. Running the terraform fmt command during the code linting phase of your CI/CD process can help automate this process and enforce the formatting standards for your team. References = [Command: fmt]2

• Question 50:

  How does Terraform determine dependencies between resources?

  A. Terraform requires resource dependencies to be defined as modules and sourced in order

  B. Terraform automatically builds a resource graph based on resources provisioners, special meta-parameters, and the stale file (if present}

  C. Terraform requires resources in a configuration to be listed m the order they will be created to determine dependencies

  D. Terraform requires all dependencies between resources to be specified using the depends_on parameter

  Correct Answer: B

  This is how Terraform determines dependencies between resources, by using the references between them in the configuration files and other factors that affect the order of operations.
