HashiCorp HashiCorp Certifications TERRAFORM-ASSOCIATE-003 Questions & Answers

• Question 81:

  How do you specify a module's version when publishing it to the public terraform Module Registry?

  A. Configuration it in the module's Terraform code

  B. Mention it on the module's configuration page on the Terraform Module Registry

  C. The Terraform Module Registry does not support versioning modules

  D. Tag a release in the associated repo

  Correct Answer: D

  This is how you specify a module's version when publishing it to the public Terraform Module Registry, as it uses the tags from your version control system (such as GitHub or GitLab) to identify module versions. You need to use semantic versioning for your tags, such as v1.0.0.

• Question 82:

  Which of the following is not a valid Terraform collection type?

  A. Tree

  B. Map

  C. List

  D. set

  Correct Answer: A

  This is not a valid Terraform collection type, as Terraform only supports three collection types: list, map, and set. A tree is a data structure that consists of nodes with parent-child relationships, which is not supported by Terraform.

• Question 83:

  How is terraform import run?

  A. As a part of terraform init

  B. As a part of terraform plan

  C. As a part of terraform refresh

  D. By an explicit call

  E. All of the above

  Correct Answer: D

  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]

• Question 84:

  You are using a networking module in your Terraform configuration with the name label my-network. In your main configuration you have the following code:

  

  When you run terraform validate, you get the following error:

  

  What must you do to successfully retrieve this value from your networking module?

  A. Change the reference value to my-network,outputs,vmet_id

  B. Define the attribute vmet_id as a variable in the networking modeule

  C. Define the attribute vnet_id as an output in the networking module

  D. Change the reference value module.my,network,outputs,vnet_id

  Correct Answer: C

  This is what you must do to successfully retrieve this value from your networking module, as it will expose the attribute as an output value that can be referenced by other modules or resources. The error message indicates that the networking module does not have an output value named vnet_id, which causes the reference to fail.

• Question 85:

  What Terraform command always causes a state file to be updated with changes that might have been made outside of Terraform?

  A. Terraform plan 璻efresh-only

  B. Terraform show 璲son

  C. Terraform apply 璴ock-false

  D. Terraform plan target-state

  Correct Answer: A

  This is the command that always causes a state file to be updated with changes that might have been made outside of Terraform, as it will only refresh the state file with the current status of the real resources, without making any changes to them or creating a plan.

• Question 86:

  How would you reference the volume IDs associated with the ebs_block_device blocks in this configuration?

  

  A. aws_instance.example.ebs_block_device[sda2,sda3).volume_id

  B. aws_lnstance.example.ebs_block_device.[*].volume_id

  C. aws_lnstance.example.ebs_block_device.volume_ids

  D. aws_instance.example-ebs_block_device.*.volume_id

  Correct Answer: D

  This is the correct way to reference the volume IDs associated with the ebs_block_device blocks in this configuration, using the splat expression syntax. The other options are either invalid or incomplete.

• Question 87:

  The public Terraform Module Registry is free to use.

  A. True

  B. False

  Correct Answer: A

  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.

• Question 88:

  A module can always refer to all variables declared in its parent module.

  A. True

  B. False

  Correct Answer: B

  A module cannot always refer to all variables declared in its parent module, as it needs to explicitly declare input variables and assign values to them from the parent module's arguments. A module cannot access the parent module's variables directly, unless they are passed as input arguments.

• Question 89:

  What is the workflow for deploying new infrastructure with Terraform?

  A. Write Terraform configuration, run terraform init to initialize the working directory or workspace, and run terraform apply

  B. Write Terraform configuration, run terraform show to view proposed changes, and terraform apply to create new infrastructure

  C. Write Terraform configuration, run terraform apply to create infrastructure, use terraform validate to confirm Terraform deployed resources correctly

  D. Write Terraform configuration, run terraform plan to initialize the working directory or workspace, and terraform apply to create the infrastructure

  Correct Answer: A

  This is the workflow for deploying new infrastructure with Terraform, as it will create a plan and apply it to the target environment. The other options are either incorrect or incomplete.

• Question 90:

  You have declared a variable called var.list which is a list of objects that all have an attribute id . Which options will produce a list of the IDs? Choose two correct answers.

  A. [ var.list [ * ] , id ]

  B. [ for o in var.list : o.Id ]

  C. var.list[*].id

  D. { for o in var.llst : o => o.id }

  Correct Answer: BC

  These are two ways to produce a list of the IDs from a list of objects that have an attribute id, using either a for expression or a splat expression syntax.
