HashiCorp HashiCorp Certifications TERRAFORM-ASSOCIATE-003 Questions & Answers

• Question 31:

  What is the Terraform style convention for indenting a nesting level compared to the one above it?

  A. With a tab

  B. With two spaces

  C. With four spaces

  D. With three spaces

  Correct Answer: B

  This is the Terraform style convention for indenting a nesting level compared to the one above it. The other options are not consistent with the Terraform style guide.

• Question 32:

  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

  Correct Answer: C

  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 33:

  Terraform can only manage resource dependencies if you set them explicitly with the depends_on argument.

  A. True

  B. False

  Correct Answer: B

  Terraform can manage resource dependencies implicitly or explicitly. Implicit dependencies are created when a resource references another resource or data source in its arguments. Terraform can infer the dependency from the reference and create or destroy the resources in the correct order. Explicit dependencies are created when you use the depends_on argument to specify that a resource depends on another resource or module. This is useful when Terraform cannot infer the dependency from the configuration or when you need to create a dependency for some reason outside of Terraform's scope.

• Question 34:

  When using Terraform to deploy resources into Azure, which scenarios are true regarding state files? (Choose two.)

  A. When you change a Terraform-managed resource via the Azure Cloud Console, Terraform updates the state file to reflect the change during the next plan or apply

  B. Changing resources via the Azure Cloud Console records the change in the current state file

  C. When you change a resource via the Azure Cloud Console, Terraform records the changes in a new state file

  D. Changing resources via the Azure Cloud Console does not update current state file

  Correct Answer: AD

  Terraform state is a representation of the infrastructure that Terraform manages. Terraform uses state to track the current status of the resources it creates and to plan future changes. However, Terraform state is not aware of any changes made to the resources outside of Terraform, such as through the Azure Cloud Console, the Azure CLI, or the Azure API. Therefore, changing resources via the Azure Cloud Console does not update the current state file, and it may cause inconsistencies or conflicts with Terraform's desired configuration. To avoid this, it is recommended to manage resources exclusively through Terraform or to use the terraform import command to bring existing resources under Terraform's control. When you change a Terraform-managed resource via the Azure Cloud Console, Terraform does not immediately update the state file to reflect the change. However, the next time you run terraform plan or terraform apply, Terraform will compare the state file with the actual state of the resources in Azure and detect any drifts or differences. Terraform will then update the state file to match the current state of the resources and show you the proposed changes in the execution plan. Depending on the configuration and the change, Terraform may try to undo the change, modify the resource further, or recreate the resource entirely. To avoid unexpected or destructive changes, it is recommended to review the execution plan carefully before applying it or to use the terraform refresh command to update the state file without applying any changes.

• Question 35:

  The_________determines how Terraform creates, updates, or delete resources.

  A. Terraform configuration

  B. Terraform provisioner

  C. Terraform provider

  D. Terraform core

  Correct Answer: C

  This is what determines how Terraform creates, updates, or deletes resources, as it is responsible for understanding API interactions with some service and exposing resources and data sources based on that API.

• Question 36:

  _______backends support state locking.

  A. All

  B. No

  C. Some

  D. Only local

  Correct Answer: C

  Some backends support state locking, which prevents other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss. Not all backends support this feature, and you can check the documentation for each backend type to see if it does.

• Question 37:

  A provider configuration block is required in every Terraform configuration.

  Example:

  

  A. True

  B. False

  Correct Answer: B

  A provider configuration block is not required in every Terraform configuration. A provider configuration block can be omitted if its contents would otherwise be empty. Terraform assumes an empty default configuration for any provider that is not explicitly configured. However, some providers may require some configuration arguments (such as endpoint URLs or cloud regions) before they can be used. A provider's documentation should list which configuration arguments it expects. For providers distributed on the Terraform Registry, versioned documentation is available on each provider's page, via the "Documentation" link in the provider's header1. References = [Provider Configuration]1

• Question 38:

  You modified your Terraform configuration and run Terraform plan to review the changes. Simultaneously, your teammate manually modified the infrastructure component you are working on. Since you already ran terraform plan locally, the execution plan for terraform apply will be the same.

  A. True

  B. False

  Correct Answer: B

  The execution plan for terraform apply will not be the same as the one you ran locally with terraform plan, if your teammate manually modified the infrastructure component you are working on. This is because Terraform will refresh the state file before applying any changes, and will detect any differences between the state and the real resources.

• Question 39:

  What does this code do?

  

  A. Requires any version of the AWS provider > = 3.0 and <4.0

  B. Requires any version of the AWS provider >= 3.0

  C. Requires any version of the AWS provider > = 3.0 major release. like 4.1

  D. Requires any version of the AWS provider > 3.0

  Correct Answer: A

  This is what this code does, by using the pessimistic constraint operator (~>), which specifies an acceptable range of versions for a provider or module.

• Question 40:

  What does Terraform use the .terraform.lock.hc1 file for?

  A. There is no such file

  B. Tracking specific provider dependencies

  C. Preventing Terraform runs from occurring

  D. Storing references to workspaces which are locked

  Correct Answer: B

  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.
